I am getting a "tic tic tic" sound and a smell of pre cat exhaust - mostly when the car is first started. Sound seems to fade away after a few minutes of running.

My first inclination is exhaust manifold and/or gasket.

Anyone aware of any common exhaust leaks?

Maybe. But it seems to get louder when you accelerate the engine, like a leak would. Plus the odor. Maybe my imagination. But I will need to look it over soon.

Re: (flat_six)

OK so I had a look and am pretty sure there is a leak and I need a new exhaust manifold gasket.


Anyone know how difficult a job and how long that might take? Turbo has to come out first per VADIS.

Re: (Chilled Man)

Is it possible to replace the exhaust manifold to head gaskets without pulling the turbo off the manifold and having to disconnect all of the turbo coolant and oil lines etc? Seems like you would just need to get the manifold far enough away to get at the gasket surfaces to clean them up.

Re: (flat_six)

Well, I have collected all of the gaskets, etc to do this job myself, including new manifold nuts. Are there any issues that I should be aware of?

I am still wondering if this can be done leaving the turbo attached to the manifold. Really dont want to disconnect anything beyond the oil drain and intake duct...

All done. Manifold leak fixed.

Cause: exaust manifold studs loosened - backed out of the head and one of the gaskets blew. What kind of a design is this anyway?? No way that should have happened.

Meh, it happens sometimes. It's chronic on other cars. I had a Saab 900 once that did the exact same thing, when I called a Saab specialist they were like "check number one cylinder front exhaust stud". Sure enough, it was loose, and tightening it solved the problem. So common they could diagnose it over the phone.

Re: (LloydDobler)

I thought about just tightening the nut, but getting the heat shield out of the way to get a wrench on it is half the battle anyway. Glad I went for the full gasket job because In my case the gasket had eroded. Bits of the metal were missing.

I used locktite on the studs and made sure they all bottomed in the holes. Hopefully that will hold it for a while.

Not sure about the exhaust manifold though. It was full of cracks! Cant believe this!
