Smobek...smobek! She's smokin' like a chimney! Pray form my baby! - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Smokin' like crazy at start-up (even after just 2 hours) and the belt started squealing constantly. I'm goin' in and hopin for the best, but if anyone has had an oil leak that hit the belt, please let me know where it came from.

TIA!

Does it just smoke at start up or does it keep on?

Is this black or white smoke?

White smoke, just at start up but not the normal poof, it's a huge cloud. I tried to take pics, but the camera couldn't see through the cloud.

She's burned off a pint of oil in the last three days at start up.

I believe I've found the problem, though. The oil filler tube collapses under vacuum. That's what was making the squealing noise, not the belt. I'm lucky because we have two Porsche dealers here within 40 miles of my house so hopefully one of them will have it so I can keep her on the road.

Delirousga...I have an idea. Since you are going to get the problem fixed anyway and there is a lot of smoke coming out, I suggest putting a beef brisket behind the pipe and putting a few drops of liquid smoke in the oil res. and making a little barbecue. Just a thought...

Well, the oil filler tube didn't take care of the problem. Took it out last night after working on it all day and here's what I found:

The smoke comes out of the exhaust. I don't see it coming from the engine bay or around the exhaust like it's leaking on something then burning. It's like too much oil is being pumped into the cylinder(s) and it's burning it off. If it sits for about 2 hours, about a cup of oil will be burned off at start-up. The amount of smoke is so big if you back into it you're completely blind, like sitting in the middle of a cloud. I'll try and post a picture in a bit if I can.

I was completely wrong about the squeal. There is no oil on the belts at all. I could only get it to squeal with the covers on. I guess the engine does not get hot enough when it's wide open so I still don't know what's causing the squeal. Since they both started happening at the same time, I'm guessing they're related.

Does anyone know if you can see the oil dripping if you have an RMS failure? I was looking around at everything and there is no visible oil anywhere. I looked around where the RMS should be located and it's all sealed so I don't know if you can see the leak or not.

Any suggestions would be greatly appreciated! I'm flying blind right now and we won't drive it until it's figured out. Working on the clutch in the 928 today since I should be able to finish it and keep 2 cars on the road.

TIA!

If you have a RMS leak you will know it. It will drop straight down and should not be connected to smoking like you described in any way. The oil will be on your garage floor.

If that smoke is white-ish, I would say you have a breach in the coolant to combustion chamber. This would indicate a head gasket I believe.

If the smoke is black, then your breach is more serious, oil to the combustion chamber.

Time for a service dept visit.
