Any one think they know
what wet wrong

Were the injectors serviced and verified?
Not sure Rich
I just want to make sure
it was not me
He had me double oil
Just run RPM up and down
Never got over 5000 RPM
Thanks
if it was never determined why it failed the first, more than likely it will continue to fail, you have to find out what caused the first failure
Many rebuilt motors fail on the same cylinder that first failed because the sleeve was bored and cleaned up ok but had been distorted by the previous piston damage.Once the interferance fit between the sleeve and block has been compromised in this way the sleeve will no longer pass heat properly and the piston will overheat and fail again.This is why we usually bore the block and fit an oversize sleeve in the event of a badly damaged piston,Chris
THanks Chris
My mech bought te block off E-bay
And sentit off to be bore out
He is sending it off again to
go up one on that pison
better have sleeve checked like he sugg. ^^^^^^^^^

And better determine the real CAUSE of the failure. If we don't learn from history, we will likely repeat history.

Don you are right for sure
Rich you may be right
I went over today to check
on my motor.He said when he
gets it back from shop he is
going to have the injectors clean
He said all the other piston seal
real good.
Just ensure to have them verified by either myself or Don. There are hundreds of injector service shops that will be glad to take your money with no validation that injectors are in specification. I've seen this on numerous occasions.Originally Posted by comanche 487
