You would have to take apart the engine to accurately ascertain the extent of the damage as well as to replace the thrust bearing and the rest of the engine bearings. Not as easy as "throw in" would make it seem.

Saying that, if the damage was just to the engine bearings only, with no other damage to the crank or block, you should be able to replace just the bearings and save the engine. But that's also when visions of building a stroker comes into play, "WYIT" and all that...

Cheers,
Constantine

Does anyone actually have a stroker that doesn't cost untold thousands of $$$, and runs reliably at the same time?

Can someone steer me to a step-by-step for checking flex plate pre-load on my 86 auto. I'm about 100 miles post rebuilt torque tube job and worried. I've tried search but get amazingly unrelated threads.

Thank you. Just what I needed. Hadn't found the FAQ's. There's enough there to keep me out of trouble for several days.

In case you haven't tried it, keywords surrounded by quote marks helps this search function work better.

Thanks. I tried the quotes but I get wild results. I think I may be using too many words so I get hits that include any of the words.

Colin,

Too funny, reminds me of my ex-wife. She used to always complain about me being in the garage. One day she did this in front of her dad. He promply told her "She should be glad, she knows exactly where I am, AND she has the "equipment" to get me out of the garage anytime she REALLY wanted me out of it ".

She didn't get it..one of the many reasons she is an "ex" :-)

Having lost an engine at 60,000 miles to thrust bearing failure and installing a new/used one from a 5 speed car i can back up the comment that Constantines clamp is the answer......Andrew and others may be happy with loosening and re-tightening the collar but you cannot convince me that that is a solution even if it is cheap....i have put 10,000 kms plus several spirited DE's on the car since and can tell you the flex plate on my 87 auto is as the day we put the new motor in and the clamp on the drive shaft.....it has not moved a fraction, period. That is what i call a solution at a very reasonable price.

For me there is just to much at stake to take a chance with TBF for lack of a 400 dollar part.
After the timing belt, the clamp was the first thing I put on my car.
Is it a full day to put it in, yes it is, but how long and how much does a motor cost.

I may even put the circlips in mine for added insurance, I all ready have a 25 MM shaft and I don't think it is going to be that big a deal to do, as my motor is all ready out .
