91 is right
I got two of them of my own and a few more of my buddies. Had one bend after cranking the next day, wouldnt crank he thought he had dead battery so he jumped it and fired it up reliazed he had blown head gasket and shut it down, too late!! Bent.
THen on the others they were only started to run home, one more bent rod on that deal, the rest spun a rod bearing a few weeks later, even the one that was caught soon as it blew, we figured it was from the force of shoving the water back into the cooling system that actually pushed the slight oil film out of the way and led to the damage of the babbit on the bearings. SO now no matter what I always recommend they change the bearings, why not for a few extra bucks and a little more time, buys you alot of insurance later. Now if you drain that oil and it comes out white.....and thick...... Tear her down because she is whiped out. Won't last a day.
I also disagree with the other fello on bearing damage for two reasons, one being you dont see any damage to the mains, even though the rods are wasted, two I Have blown alot of head gaskets and seen alot blown, and havent ever seen a bearing failure on anything except these super coupes, from turbo coupes to a twin turbo porscha, and these SC's are the only ones, I have seen with rod bearing damage when I drop the pan (now a manditory when i do a head gasket on these badboys) and it has always been on the last cylinder on the driver side, no others. And it always wasted on the top half. (that is if it is done at same time head gaskets are changed)
CHeck my history we have discussed this topic numerus times, you might find alot of info there to help you.
