Drop motor disassemble carefully paint marks all over the timing belts, then remove stop filming replace belts ‘wherever’ restart filming pretty red paint on the valve covers (lipstick on a pig?) reassemble charge 12k
Don’t you just love ‘professional’ work by clueless techs? No slam intended for the true professionals. They are worth every penney they charge.
check out the size of that torque wrench to tighten the cam covers down..... for what... five or so ft lbs?
Only saw 2 things wrong..first off, turn the heat on in the shop. Second, remove that car from the shop.
I'd love to learn more about this process. If any of you folks could point out errors or oversights shown in the video, Id appreciate it. Thanks, - Sam in Saratoga
Marking up the belts is a newbie waste of time. Been there, done that. The entire process of setting the cam timing was totally cut from the video. The only part of a Major that requires any true technical skill is the cam timing - the rest is all nuts and bolts. Detailed, finniky, fragile nuts and bolts. If you type 83958 in the search engine, you can follow my efforts on a Major. Like I say, setting the cams correctly is a bit of a brain teaser. It requires a lot of care, thought and patience. A ‘low IQ’, time pressed, inexperienced tech will screw it up in a big way.
Don’t forget the water pump. That was the worst part. Reading threads about folks doing it 3 times and it still leaked... Realistically, timing the cams was worthless. Unless the car runs poorly, it’s likely spot on... checking valve clearance was more useful, though almost every valve was in spec. Next time, I think I will just change the belts and tensioner sand call it good...
Agreed. Testarossa pump seals are a miserable design. All the different versions of the seal/impeller are a confused mess. But hopefully a hydrotest will catch a bad seal or install before the engine goes back in. I disagree on setting cam timing. It MUST be checked if the cam pulleys come off for a new seal. If they don’t come off, it is still highly recommended to double check with a degree wheel.

I agree about cam timing but not waterpumps. I have never considered pressure testing a waterpump a good use of time. Never done it, see no reason. Shop is a dump. I wouldn't bring a Yugo to a place like that. Cannot even spell "Major". Just who I'd use.
Yes - but your years of experience have taught you the ‘secret’ seal that seems to work better than those which Ferrari specs for the Testarossa. ;-)
I think you guy's missed the fact that this is not a "Major" service...........it is a "Mojor" service!!!!!!!!!!
I do both, cam timing and pressure test water pump. Wish I had Brian's confidence with seals I've replaced. Image Unavailable, Please Login Image Unavailable, Please Login
From the threads I read, many folks had leaks 100 miles after the major, not right away. Would a pressure test show that? I always thought perhaps the waterseal wasn't put in square and the friction parts wore unevenly??? You can pressure test it with air... put does that mean it wont leak? This thread is bringing back bad memories...
Just use factory seals installed correctly. I didn't have years of experience the first time and it didn't leak. I was shop foreman for what was at the time the biggest dealer in the world and no one in the shop was having trouble with leaks. I don't understand the issue but I can guarantee you if I saw what was being done I could identify a problem while it was being done.
Pretty hard seeing air leak out. Air being compressible and with the internal volume as big as it is it would take forever to know if there was a small leak using air.
I see that there are two camps: replace the WP seals and dont replace the WP seals. To someone who believes they should be replaced: If there are no signs of leakage, what is the advantage to replace them? Is leakage difficult to identify?
Sure wish I could spend a few days in your shop to learn your techniques. It would be a great time for a diy guy!
