engine failure after rebuild
engine failure after rebuild had to rebuild my motor 2 times. losing oil pressure after i try laying into the throttle. have had 2 different machine shops work on it. it appears the thrust bearing is being taken out.....like the crankshaft is being pushed forward and causing excessive heat and causing bearing failure.
I have a vigilante converter and it has anti-ballooning plate. i was also told that to much line pressure in the transmission could cause this problem. using factory crank, compstar rods and H series bearings. Using arp main studs and block was not line honed. Engine failed both time in about a week any feedback would be greatly appreciated.
check mods on SIG.

When it comes to wiping out the thrust it is usually the converter and not transmission. What kind of spacing does the converter pads have between the flexplate when fully seated ionto the transmission?

When you added the procharger did you have the converter rebuilt for it? Like other said, its probably the converter ballooning and pushing the crank, and eating the thrust bearing.
+1 with checking the converter, going from N/A to FI would require a different converter. When choosing a converter that is one of the things they ask and why they need details on your set-up and goals when they make one for you. When I got mine from Yank I pretty much had to tell him everything I did with the car and what it was being made to do
