Over the past month I've been noticing a few drips a week under the car while sitting in the garage. It also drips a few drops when I run it, because the oil hits the heat exchanger and I get some smoke form the rear passenger side wheel well.

So today I decided to check out what the problem might be and try to fix my first oil leak...

At first I thought it was the oil line and tightened it (blue arrows). I then started the car and revved it in the garage. I left a newspaper underneath to see if any oil would drip... Lo and behold did it start dripping! My tightening seemed to have made things worse.

So now I'm not sure what to do next.

Any ideas?

Thanks!!

Tightening a ring clamp only further damages the bad hose. You picture shows the hose is badly extruded. I would start with a new hose, followed by a good cleaning so you can trace any other leaks. With that much oil on the exhaust, I'll bet there is quite a fog when the manifold heats up!

I don't recognize the hose with the ring clamp, and the clamp does not look German. That may be an improvised repair from a prior oil leak. How many miles are on the engine?

Thanks, I'll look for another hose. Wasn't sure if it was bad or not. 101,000 miles on the engine.

I think I found the line I'm looking for - it's number 46.

But if that's the one, which one of these should I get?

ilko

Just went back to the garage to check - it's not #46, because it has the bolt on one end and a clamp on the other. #46 has bolts on both ends...

I may be wrong but that looks to me like #29.

you've got more than one leak in my view. best thing to do, powerwash the underside of the engine, drive it and see what you find. the oil is going to travel a lot around the bottom of the engine making it all the more challenging to find. I just pulled an engine and have nearly finished resealing it. I changed both oil lines, and all the seals. its something to expect to do around 20 years of age of 100k. good luck

I reckon it's #29, looks like the suction side out of the motor.

ilko

You guys are right, it does look like #29.

I want to clean the underside of the car, I tried yesterday with Simple Green and paper towels, but as you can see that didn't achieve the desired results. I don't have a pressure washer, so the other option I can think of is a car wash place. I'll just dump $10 worth of quarters, take my time, and see what happens. Is there anything else I should try?

Thanks!

I've had decent luck using Gunk Engine degreaser. I also just tried a 3M produce that worked well. What I do is get the engine warm, apply the product, wait 5 minutes or so and spray it off with the garden hose. Where you are trying to clean, you will probably have to pull the wheel off to get in there. I just did my 130K mile car that was pretty nasty and am happy with the results. I won't get everything but will get you 80% of the way. I can't stand working on a slimy engine.

Gunk does work well but it will leave a smell behind for a while. Good luck finding the culprit.

I recently fixed a leak on my 964 turbo by cleaning everything up, then taking a white shop rag and tearing it into 1 inch strips. I tied the strips around every potential leak that I could get to, then went for a short ride. Bingo!, it was easy to see that the hydraulic fitting on hose # 46 above was leaking. I took it loose (thought there might be an o-ring but there was not.) and cleaned both ends up, reassembled and NO LEAK.
Almost nothing more satisfying than getting one of these things remedied.

Better to be lucky than good.

Zero dollar repairs are the best!!!!

Clean with simple green. It is #29. And get a good clamp from Porsche. You are about due to replace all the hoses.


And I think this in not your only leak.

A tip I had from a good mechanic to trace oil leaks is to dust with talc or similar powder after cleaning. This apparently stops the runs spreading so quickly so helps pinpoint. I haven't tried it and suspect it works better when there is some vertical run but may be worth a try.
