If the oil pickup was not picking up oil then a bad chain of events could be triggered .One result could be heat and ultimately a failed rod bolt .Not knowing the angle of the car and where the oil pickup was in relation to the oil pool it's only speculation without facts .
Sorry for your misfortune.................

 

fpb, you really think that could happen? I suppose if it were a steep enough angle, huge clearances, long enough time, maybe. I know water will do it quickly but oil????? Im being serious.


Not funny, oh well, maybe a little funny.

 

Thanks for the feedback.

Some answers:
- Road Atlanta and Roebling do not have any camber like Daytona and others.
- Ironically I did a few Auto-x with the VF supercharger, but ripped it off and did a big project taking the car back to stock with just intake, full fabspeed exhaust and tune.
- According to my indy the 6 cylinder's piston is not connected to the crank anymore. Crazy issue they had not seen before. being disconnected, it was burning fuel in the cylinder and caused other issues. Crazy and unfortunate.

 

I've snapped rods in half before so that's not unheard of. The motor sounds rebuildable so don't run it anymore. Cases are expensive these days....

PS: The late Carlitos's 3.4 ran for 25k miles with a blower and is still racing today (without the blower) with 110k mles on the original, untouched motor. The trans just recently broke a shift fork but the internals all looked good. He rebuilt it of course....

 

Plenty of people own these cars and live/park on the steep streets of San Francisco. Even parking at odd angles. Seems difficult to believe that that was the cause.

 

Can you be a bit more clear on this?

I had a Harley throw me on the ground and jump on me once. After it broke my leg it slid up an embankment so that the engine was heads down and the oil flowed/got sucked up under one piston, it blew the cylinder base flange off when it tried to compress the oil under the piston, cracked the case too.
That engine was dry sump. We figured the scavenge pump was out of the oil in the bottom of the case at the pickup so it just pumped all of the oil out of the tank and POOMP goes the engine. (that is kinda what it sounded like) Only took ~20 seconds. That oil was hot though.

You would think that with the opposing pistons there would be enough room to "slosh" the oil back and forth? I don't know how or what any oil would get compressed against under the piston in these engines.
I know that in the early 3ltr air-cooled engines the oil could get trapped in the cases and foam and overheat. Porsche redesigned the screen around the pickup to address that.

 

seems to be I suffered from "a bad day". Thanks for the feedback. Flat6 put a bug in my brain, so I have some interesting decisions....

 

If you ever decided to sell it as it is, I might know a buyer for it.

 

Imre, do you really need another 996?

 

I dont think you can hydrolock any engine from the back side.

 

I think he meant it leaked past the rings to the top of piston which still seems odd.

 

Pic of the car at an angle? I've had vehicles at much steeper angles under operation than on jack stands and never had starvation issues. I'm willing to bet there is another reason for the failure.

 

Not possible.

 

Hence the "seems odd" comment. Maybe it was a combo of the SC, bad AOS, engine on side? This thread has convunced me not to lift my car to work on it. I will be using a low profile creeper.

To the OP; could you take some photos of the engine while you disassemble?
