Angry Recently purchased, recently deceased 944 N/A

I bought an 87 N/A 944 a few months ago with 84000 miles on it for $3500. It looked like it was in great shape. I drove it for about a week and a half, and one day on my way to school the engine was at about 4000-4500 rpms in 2nd gear and KaBOOOM! The engine literally exploded! The engine blew up with such force that it blew a hole the size of a fist right through the bottom of the block through the oil pan.

Anyone have any idea what could have caused this? There were no warning signs except for a little white smoke at start up. No engine knock, nothing like that... just out of the blue. I took it to my mechanic (who specializes in Porsches), which is who I purchased it from, and he said that he has know idea how it could have happened, he says that these engines are "bulletproof" and is amazed that it self destructed out of the blue like that; he thinks that one of the connecting rods must have just failed. I didn't abuse it... i only had it a week and a half! I took it up a local hill, Giants Diapair, where there is a hill climb race the 2nd day I had it so I could really take it for a test spin. I shifted it a couple hundred rpms before red line, but that was it. It ran great after that but about a week later is when it exploded. Mearly that couldn't have caused the engine to explode. I need the input of the experienced members of this board!

P.S. Needless to say i'm now in the market for a 2.5L 944 short block and oil pan. (maybe even a 2.5L long block) Your input is greatly appericated! If you'd like to mail me personally: superheady@adelphia.net

Nope... the oil was fresh. Just changed when it was purchased. And it was at normal running temp.

The only reason I can think of why the bottom of your engine will explode is if there was a whole in one of the cylinders. While driving a lot of gasoline reached the only at the bottom of the engine. The whole will also get bigger in the mean while, especially when you drive in the almost red zone. And then at one time the gasoline will explode.
Nothing you could have done to prevent this, except taking the engine apart.

I don't say this is whay happened. It is only my oppinion.

Maybe the engine hydro locked some time ago and bent a rod slightly.. after that it was just a question of time before dissaster came.

Metal fatigue!

Heat -cool - heat - cool cycles! Causes the metal to expand and contract, it may have finally hit its limit.

Sorry to hear that. I can relate with any consternation as it's hard to tell the true condition of an older car when we buy it. I personally recently just got an '86 944 for $4k and sometimes wonder if something is lurking around the corner for me. But buying an older car is typically understand as an as-is condition, so we're stuck with the finances of repairs even if it's hours after the purchase.

Hope your car gets up-and-running soon! Good luck!

My 2 cents? The white smoke at start up is a clue. Most likely burning antifreeze from a failed head gasket or cracked head. If this is true, the water in a cylinder might have put enough stress on the rod to cause a failure. Those fragments then blew out the bottom??

Disassembly will yeild more clues.

I might be able to get you a shortblock or an long block out of 924S 1987 with 53K miles on it. I am located in mass. so you would need to ship.

Let me know and we can talk price.
