New Engine Oils for Flat Tappet Cam Cars!


About a year ago, I wrote about recent changes in engine oil packages that pose threats to older, flat tappet camshaft operated car engines. In essence, manufacturers removed zinc dialkyldithiophosphate (ZDDP) from oils to minute trace amounts in order to satisfy upcoming regulations for new diesel and heavy truck emissions. Word is new trucks will be running catalytic converters and Zinc is known for fouling them up. Car manufacturers years ago switched to roller camshafts for mass production and those style cams don't require added zinc protection the way older, surface hardened gray iron camshafts do.
The results of using the recent formulated low zinc oils have been catastrophic. Camshaft failures inside of 300 miles is common, especially on new engine builds. Older engines with a bit of zinc embedded on the lobes will stay protected for maybe one oil change cycle but then they're in danger. When I last wrote about this topic, the suggested solution was to add engine oil supplement (EOS) or use a synthetic grade motor oil. Since then, another alternative has arrived.
Union 76 HIgh Performance Motor Oil, Kendall GT-1 High Performance Motor Oil 20W50 and Phillips TropArtic Racing Motor Oil 20W50 are being reformulated with more ZDDP starting in March 1, 2009. These oils will contain 1200 ppm of zinc which is the required amount to provide cams with antiscuffing, antiwear and oxidation inhibition.
Some Questions and Answers about engine wear and ZDDP
Q:Why do the older camshafts wear out quickly without ZDDP?

A: Older flat tappet cams such as the 428 CJ, Ram Air IV, LS-6 and LS-5 and other high performance engines were surface hardened only. A car with high spring pressures and not enough zinc in the oil can wear through the protective surface very easily. Pitting, uneven lobes, severe wear patterns appear very quickly. As the camshaft profile changes, power loss occurs.

Q: Other than losing a cam and lifters, are there other dangers?

A: Yes, we've seen a few of these engines stripped down last summer and witnessed camshaft bearing wear and lopsided bearing journals. A significant amount of displaced metal appears in every case. If the metal isn't found in the oil pan, it is somewhere inside the engine block, in an oil gallery or pump main. In such instances the reccommended procedure is to tear down and flush the block to remove loose metal. That's the only way to assure no further contamination. At the very least, the cam bearings must be changed.

Q:My engine is a fresh rebuild. I lubed the camshaft with the factory supplied lube. Do I need this EOS additive?

A: After you've done your initial engine break in, You drop the oil pan plug and change to fresh oil. It doesn't matter which brand you pick, likely it will have less than 1200 ppm of zinc. That protective goo on the cam is for the most part, gone now. It did its job during break in. You still need to use EOS or one of the new formulated oils at the top of the article for protection.

Q: My car is street driven and I use 10W30 oil. Wouldn't switching to a heavier grade of oil reduce horsepower?

A: In more recent engines where tolerances are tighter, say a 4.6 Ford or the last of the 5.0 Mustangs, you might lose some power. The 5.0 liter Cobra engines from 1985 and up used roller cams so it's not an issue the way flat tappet cams are. If you want to keep using 10W30, try an additive instead.

Q: Where can I get EOS additive?

A: General Motors Canada has the additive for sale. It's been reported the product is no longer in service at US dealerships with an invalid part number. Likely lots of dealers have old stock available. Competition Cams sells bottles of their own brand. Either will work fine. ZDDP or zinc is the ingredient you want.

PHS Interviews: Sean Mattingly of UltimateGTO.com


Pontiac GTO fans have been visiting UltimateGTO.com owned by Sean Mattingly for years. A megasite rather than a simple portal, almost anything related to the first US muscle car is there if you look hard enough. It has over 16,600 pictures of real GTOS, Tempests and Lemans from every year. This year, TUGTOPS is expanding with new features, so we thought it was time for another interviw with Sean Mattingly.

PHS: TUGTOPS recently celebrated its 12th Anniversary. When you first started, did you think it would ever get this large?

SM: In 1996, no. My computer at the time had a tiny 40 Meg hard drive, and going on a quest to collect a photo of evey GTO seemed impossible. In the beginning, I was only saving photos of 1968 GTOs on large 5.25 inch floppy discs. I think I fitted 8 photos on each floppy. It seems pitiful today compared to the fast commercial server I'm on with Terrabytes of storage space. What surprised me is how many "car nuts" would contact me from around the world with tales of their GTO lust. If you can get high on car enthusiasm, this is it.

PHS: My favorite section of the site is advanced picture search. I use it all the time for research purposes. Do you have a favorite part of the website; one that still gives you lots of pleasure to this day?

SM: The Advanced Picture Searcher is my favorite too. If people haven't seen that, they're missing out on my buddy, Jeff Klein's, brilliance. He's helped database every photo on the site. Easily a decade before other sites even thought of organizing pic galleries with "tags", we'd built a searchable database. If someone needs to search just for GTO "pedal cars", there's a dropdown box on the screen to see 24 pics of pedal cars. If you get a hankerin' to see lesser known models like the "Custom S", Advanced Picture Searcher will show you 63 of them in 2 door hardtop, convertible and 4 doors. See right there, you might have learned something interesting if you didn't realize there was a four door "Custom S" that resembles your GTO.
One of my daily pleasures is reviewing photo comments. Every day, web visitors leave comments on the cars. Usually, they have favorable encouragement for the car's owner. Once in awhile, a guy will find a pic of his long-lost GTO and tell the owner, "Hey, that's my old car! My Dad made me sell it when I got my first speeding ticket. Good to see mny old car is still alive."

PHS: Looking over the Wide Track era, Pontiac added many new pieces to keep the GTO a front runner. At one point, the image solidified and people perceived GTO to be the best performance intermediate available. Sales statistics suggest that happened in 1966. In your opinion, what were the strong and weak points of the 1966 GTO?

SM: How can a person explain love at first sight? Even if one of these cars was sitting in the middle of a junkyard among many other makes, it's the first one you have to walk up and examine. Even the King of Sweden adores the 1966 GTO and drives his in parades. Of course, I have a photo of that along with 1,282 others. I've tried to gauge the popularity of different model years using weekly poll questions on the main page. I asked people what year they prefer. If you thought 1966, you'd be close. In polls conducted from 2001-2003, the '69 GTO won. From 2004-2006, the '67 GTO was most popular. In the past three years, it has been a tie between 1969 and 1967.

PHS: The GTO along with the Mustang, was one of the first muscle cars to be restored in the late 1970s. Your website has remarkable tools for the restorer from vintage pics and many variations in trim and options, links to Performance Years forums and a large dealer list by zone. How did you start a zone list file? Dealer codes are only seen on build sheets, sales receipts and PHS documents.

SM: I started the Pontiac Zone and Dealer Code list as a side project. It's located under "Text Topics" on main page. For the most part, car owners contributed their codes via email and I add them to the list. Some of my helpers will walk around car shows and jot down zone codes and dealer names from window stickers and send them to me. I was sure someone would volunteer a printed complete list. No such list has surfaced. Since 1996, I've had people liquidating two different estates tell me they thought such a book or document was in their dad's collection. Neither of them were able to produce a master list. So until one appears, we have over 1,050 user submitted codes with towns and notes.

PHS: Sean, you're adding more features and content this year. What can visitors expect to see on TUGTOPS soon?

SM: I'm adding more GTO pics and picking out bigger images for "Picture of the Week." The backlog of unposted material is huge. I've probably 2,500 to edit and database. I'll post some news items on GM and the current demise of the Pontiac brand. I wish there was positive news to report on that.

PHS: Like most people, you have a day job, tending operations for radio stations in Indiana and doing a DJ drive as well. Is it difficult to get spare time?

SM: The site is set up so I can administer it from pretty much anywhere. It helps when I'm on the road. I can't make a career out of GTOs can I? If I made UltimateGTO.com my main business, the site would have to be plastered with ad banners. I'd never do that to my fans. It's a fun hobby site, I'll keep it that way.

PHS: In the summer, you've toured all the drive in theaters of Indiana and posted photos of many. Is there anything you'd like to do with your GTO that you haven't tackled yet?

SM: I caught the drifting bug at the Bob Bondurant School of High Performance Driving. I'd like to do a perfect 360 degree spin. GTO drifter, Rhys Millen, showed me how it's done there. I keep trying but can't get it just right. For some reason, my non power brake car has trouble nailing it back home. I can make a few passes in my '68, but then the cops have to come and watch...

PHS: From my perspective, once prices at auctions topped $50,000 for decent GTOs, it hurt the hobby. We saw less GTOs and other real muscle cars appear at cruise nights and owners became reluctant to drive them. I haven't seen a real hemicuda in four years. What is it like out your way? Do people still enjoy their cars the way they used to?

SM: Here in the Muncie, Indiana area, land is cheap. The countryside is flat farmland with plenty of pole barns. You know what's in those barns, tractors and old cars! I don't think people are overly scared of driving them around here. The towns are small, traffic is light, people are still polite. Heck, I still drive my GTO down to the shopping center to get a haircut. Nobody messes with the car. Just today, I saw a shiny 1966 LeMans at Subway. There's a lady who works at a fast-food place with a purple metal flake GTO with skulls hanging from the rear view mirror. I also know a guy with 5 CanAms in his side yard, all in driveable condition.
With today's technology, if you wreck your classic beyond hope, who cares? With the internet, you could find another one and have it in your driveway in about a week. Searching for cars and parts has never been easier with the internet. In my opinion, it makes no sense to try to "keep the miles off" a car. Life is short, put ON some miles flying down country roads in an old-school car made without any computers in it! Enjoy the hell out of it and yes, use it up without remorse.

PHS: Everyone it seems has a favorite GTO. If you won the Powerball Lottery and money was no object, what model GTO would end up joining your 1968 hardtop?

SM: I might get some kind of pace car. The Indy 500 is south of us. I regret Pontiac never made a Pace Car edition GTO. They should have made a Hurst GTO pace car, darnit! One of the orange and white Camaro convertible Pace Cars would be cool.

PHS: What are some of the big changes you've seen with GTO owners since you've started this site?

SM: People used to write in telling me how "rare" their car was. Now they can browse through pictures, look at maybe 45 pics of cars with the same paint and roof color. Suddenly it's not so rare, plus they can correspond with other owners. It's great to see people sharing stories and info about their GTOs.

PHS: A great feature you have is continual updates on news items related to GTOs. You've covered car crashes, street racing arrests, notable auctions. What's the strangest story you've seen involving a GTO?

SM: There were so many. A lady won a new GTO on "The Price is Right" game show. The prize car they delivered had been previously wrecked and repaired. They didn't disclose that to the lady and she sued. Another one is the Police Chief in tiny Boones Mill, Virginia, with his 2004 GTO patrol car. He's in the news for ticketing speeders or fighting with the mayor and the town council. Last one I saw, he bought a good size yacht at a surplus auction. Not having a lake for his new yacht, he built a pool for it in the front yard and puts it on display as a lawn ornament. OMG the photo is hilarious.

PHS: Your early hobby car experiences are documented in the website.At one time, you bought a GTO. What made you buy one over say, a Trans Am or Chevelle?

SM: Since junior high I liked Pontiacs. I would go the public library and read all the car mags they had. When shopping for my first car, I tested a used Smokey & the Bandit TA. It was way out of my price range. I also admired the Buick Grand Nationals. Instead, I veered off to the GTO world and am thrilled with it. My wife won't let me buy any additional cars with one exception. She says I can bring back a '77 Bandit Trans Am anytime. I just might do that someday as a surprise!

Chrysler Brinkmanship,Cerberus style


Cerberus, the three headed dog to the gate of Hell and guardian of Chrysler, is playing brinkmanship with the CAW and Canadian government. Representatives through an unnamed source within the company has claimed the company cannot afford to match the terms of the present CAW deal as negotiated with General Motors this year. The source said it would be more feasible to move the entire tooling from Canada to USA and continue making vehicles there instead of matching the deal.
It seems to me they are bargaining in bad faith without adequate back up.As they are in default on previous loans as it stands, a good case can be made for the government to seize assets and force a shutdown of the Canadian subsidiary until proper reparations are made in full. As a private company, Cerberus doesn't reveal proper accounting for assessing true financial status. Looking at Chrysler from the outside we see a very dim picture. The last major retooling was for a full size truck, a limited market V8 performance car and relatively large displacement V8 engine. None of this augers well for a future where gas will be expensive and a hard hit North American market. The smaller cars are adequate but larger models are either old or not fuel efficient to face the new reality.
Looking at their cash liquidity situation, we see nothing but trouble as well. In a private enterprise situation, a company must either adjust and pare down efficiently or suffer the consequences. Since auto makers here don't really operate in a private enterprise model with unions and government regulation, it stands to reason proper adjustment should be made in their business plan to compensate for those factors. It is clear now no one had done so at Daimler Chrysler or Cerberus. In light of such spectacularly bad management, LaSorda have the nerve to demand major changes to suit their poor business model.You are wasting time!
It's time for the feds to walk in, lock up the plants and take possession for nonpayment of loans and suspect business activities.
Cerberus should have studied Classical History more. They would have learned that Hercules defeated Cerberus and brought it from the Gates of Hell. He used his bare hands to do it. They would have also learned that Cerberus was easily mollified with cake as Psyche learned as she went down to bring back a beauty charm for Venus. Sibyl also bribed the mangy mutt with cake as well. So we have a dog that acts as a bully, is defeated bare handed and can be bribed with cake. How fitting! Well we tried the cake already, let's send Hercules down.
FLASH!! Workers have seized a Chrysler parts manufacturing facility in Windsor, Ontario to prevent loss of tooling and vital componentry needed to complete vehicles and force a fair job loss settlement procedure. The revolution starts now.
