I've yet to blow any of them, the 924S motor is living in an 86 944 now, the 944S is still doing DE's with its new owner and the S2 is still going dispite the TB break i had in august. The S2 did get the 968 engine about 6 years ago because the original motor had a cylinder wall get scored to the point of eating massive amounts of oil.

Hmm...well:
- My first car (1987 Porsche 924S) was a project car, bought assuming it needed everything done to it...motor runs but probably pretty toast considering it has no oil pressure (which is why it was parked before I bought it in 2005).
- Bought a 1984 944 that had sat in a field for a few years, idiot son of the owner decided to drop a battery in it and crank it over a few hundred times to try to start it (guy was in his 20's, I was maybe 17)...got it as a parts car with another 944 I bought from him...turns out he destroyed the cylinder walls by cranking it, because squirrels/mice had eaten the air filter and stored seeds in the air cleaner box.
- Recently purchased a 1986 Porsche 944 Turbo from an individual who allowed the car to be driven by a friend (probably saw the post in the Turbo forum) who did not do any maintenance or check fluids...ran the engine out of oil, threw a rod (86,XXX miles on the engine, all original)
- My Zermatt Silver 944 Turbo (also an 86) was on it's second engine. I don't know what happened to the first one, but it was replaced by a sub-40K mile 951S engine. I discovered crank walk in that engine after it destroyed 2 torque tubes I put in it (had a bad one when I bought it, then a decent used one, then a 1800 dollar Constantine TT, completely rebuilt with a brand new DS) and 2 Clutch Kits, one of which was a brand new Sachs Turbo Cup Clutch kit. Engine still runs perfectly, you just can't keep anything attached to it for more than a couple thousand miles without it being completely obliterated. It is now being replaced by something else...something more sinister.

I took my car on a hard canyon run this last fall and all seemed well. Got back and parked it in the garage.

The next time I started it a week later I hear a very loud Knock-Knock-Knock-Knock coming from the engine. I don't remember hearing anything wrong with it in the canyon but apparently something happened. It sounds like it's coming from the back side of the engine or possibly the bottom.

I'm not even going to try to fix it. I'm done putting money and time in that POS motor. An engine swap was the plan from the start so V8 here I come!

Woohoo!! 2 LS Swaps in a row!!

Not exactly "blown" but on January 12, 2016 we cracked my 83's original block. Sad day, especially after having the motor out for a month to replace a bunch of seals including leaky oil cooler.

On the plus side, we got a donor block, doing a full engine build on a stand for her this year

Here's a video of one of her last days. We ended up replacing the oil cooler seal and running it a while more before we realized it was a cracked block. Fountains of coolant out the tailpipe.

Now for a slightly positive report!

Except for going to war with the cooling system near the end of 2015 (finally got it good again after two coolant flushes and a thermofan switch), and then breaking down miles away from home, once due to the DME relay biting the dust at a concours event, and my speed and reference sensors leaviing me stranded in the middle of an intersection during rush hour, I've had almost 8,000 trouble-free miles of no engine blow ups!!

But I did find two drops of oil on the garage floor....God doesn't know where it's coming from on the car...

two drops?

that's like hitting the lottery. Geebus.

To drops of oil.

This has to be one of the smallest registries on the internet.

I just think the pain is too fresh for most.... too soon, too soon....

Based on the number of rebuild threads alone, most people just aren't willing to relive the ordeal... PTBD (Post Traumatic Blow-up disorder)

I rebuilt my 87 NA when I got it as race car. Coming up on 300 race car hours with no issues. There is a lot of idling and a lot of 6,000 RPM in a race cars hours. oil changes at 10 hours rod bearings at 100 hours

Lost my engine October. Spun bearing and wiped out the crank. Also noticed #1 cylinder had something get in and damaged the piston and cylinder wall.

The othe pic didn't go the first time.

Some of us do rebuilds just because we have too much time and/or money on our hands and we want to fix those problems.

Interesting that none of these seem to read "my properly maintained car suddenly blew up"


It's all "I bought an old car that wasn't maintained and surprise....a 30 year old hose, belt, or roller broke!!!
