After Sebring Head gasket woes, replacement engine has bigger problems
While running my 944 S2 SP3 car at Sebring I blew a head gasket. I replaced it at the track. The repair lasted 2 1/2 sessions and it blew again. Probably a warped head and no way to repair it at the track.
Having only 4 days to get the car ready for a NASA event at CMP, I decided to swap in a known good engine from my S2 powered street car.
In swapping the engine I removed the intake manifold (easier to pull it out the top that way). When I replaced it, apparently a piece of the casting came loose and was sucked into the engine. It was probably in there since the manifold was made, but I must have disturbed it. I started the car and after about 2 seconds it started to make a terrible racket, I shut it down and looked into the bore of the no. 2 cylinder with my endoscope and saw pieces of metal. The good news is that the bore looks OK. The bad news is that the top of the piston has been peened over and needs to be repaired or replaced. I will have to drop the oil pan to remove the piston and rod and will check for any other damage. Here is a picture of the metal pieces I found in the cylinder. They are aluminum casting.
