Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Suspected cause
Most likely a chine guide broke and the chain knocked a hole on the case of the engine.
Leading evidence: 'chine guide broke and the chain knocked a hole' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'chine guide broke and the chain knocked a hole' (1 discussions; 0 report identifying it and 1 suggest it). No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Driving down the highway, suddenly I lost power. Luckily I coasted off an exit into a gas station.
It was sort of running, then it just died as I coasted to a stop. Tried to restart, and it was running rough for a couple secs then died again.
I looked at the car, and there was oil leaking out on the right side of the engine toward the back of the car. Oil leaking down the headers. There was a trail of oil drips down the road leading to my car.
When the tow truck pulled my car up onto the flat bed, once the front end angled upward, oil literally poured out the back right of the engine. I couldn't tell where it was coming from.
I had the ims upgrade done probably 60k miles ago. It didn't make any crazy sounds when it lost power. It's a 99 carrera and it has 169k on it. I've driven it every day for the last 10years.
Any ideas what it could be? Not sure what would cause it to leak in that location - but it's obviously something big and bad.
Yeah it's been a great car all this time. Criss crossed the country many times.
I looked in the engine bay and everything looked fine with a cursory search. No oil spray or obvious damage, from what I could see.
No oil coming from the front or center of the engine. When I first looked, right after I stopped, the oil was dripping down the right header. When it was tilted upwards for towing, the oil poured down the engine itself, but I couldn't see from where.
Any insight would be appreciated!
Let's not jump into any conclusion by guessing. Lift the car and see where the oil leak is coming from. Then do a proper diagnosis and go from there. Guessing just adds false information and helps no one.
Yes.
If the engine leaked oil when the car was tipped that direction, it would be rare that a hole is in the bellhouse end of the block. The car would need to be tipped the opposite way for that to happen. Never know, though.
169k. You got a good one.
Its still very upsetting to lose an engine, regardless of mileage. I do think Cuda's issue and maybe even this one shows the case for more invasive PM before the miles rack up. I think the M96 should be dropped no later than 60,000 to 75,000 miles for chains, guides, etc. If you didn't already do the IMSB upgrade it would be a perfect time to do that as well. Either way, I think 60,000 is as far as I would venture w/o dropping.
Well I don't know what happened yet - I'm in a tow truck for a couple hundred miles. This happened 700 miles from home in northern California, somewhere north of Redding.
I was on my way to Bend , where I was going to be for the next couple months. Have my cat with me, too - my traveling partner.
I didn't want to leave it somewhere far from me, so I'm towing it to Bend. I'll bring it somewhere this week and see what the diagnosis is.
I'm really bummed out and sad to think that I may not ever drive it again. It was a great car and has brought me all over the US, in all weather, and never let me down once.
There is a good Indy in Bend, German Master Tech. They get good marks on air-cooled cars, but I think they know the newer stuff too. Lot's of PCA guys like them.
There is a Porsche dealer in Bend as well, but I'm not sure they'd be the ones to go to for this? Not to say they are bad, just a question on whether they'd do anything other than try to sell a crate motor.
What do you think of this one Jake? Is PM replacement of chains and guides called for at some point? If so, what would you figure on average mileage to do that?
Yes, this is the reason we developed the master linked main chains.
As far as a mileage point to do this, well, that's a loaded question, because the 3 and 5 chain engines wear differently. I base this from measurements of chain rollers. I measure 20 rollers at various points of the chain and average their numbers, then make the decision from there.
Bring it to Albany, Oregon and let me remove the engine and turn it into an electric porsche! Faster than stock 0-60, 400+ft/lbs of instant torque and tons of fun... actually I've been talking with the guy who helped me convert mine about starting a business around electrifying Porsches... if there are any intrepid souls out there, PM me!
Rusty, please update your original thread. I think quite a few of us are interested in your observations thus far and how everything is going with your electric experience.
