FWIW-
Below is an ameail I received from a customer earlier this week.. Look what he says about his lifters:
Quote:
After talking with you on the phone over the weekend, I took the other cam cover, assemblies, etc. out to send you all the lifters. On my 70K motor, 21 out of 24 lifters were completely locked up. But it only gets worse. If you remember, on the drivers side, the intake cam was off one tooth. That is the side that the Durametric said had the cam angle off.
But looking at the passenger side, the exhaust cam was off two teeth!
Now I bought this car two years ago (used), and when I took this passenger side cam cover off, I noticed that the plugs, etc. had clear "goop" used as a sealing mechanism. So for some reason or another this cover had been off before.
The solenoid pads were just as worn as the other side, I don't know yet if that solenoid works properly.
But it continues to get worse...
Since I took the headers off (the Delubozparts headers - hopefully your testing finds they are worth it) to get the covers off without dropping the motor, I looked up from under the car into the exhaust ports of the head. Shrapnel is stuck in one of the valve openings. $&%@!&
Time to take off the head (which is surprisingly easy without lowering the motor). Head looks to be in ok shape, nothing that can't be machined.
Finally, take the head off and see a bent intake valve, and a cylinder full of debris. The piston is in tiny pieces, the connecting rod is in pieces and looks like it was hit with torch (discolored), and the cylinder sleeve is very scored (but surprisingly not chipped viably)

Here is a pic of his connecting rod...
All he thought he had was a bad vario cam chain tensioner wear pad...
This is a 70K mile engine.
