Guys,

Got a leak between the head and the manifold, how much of a bitch is this to do? Looks like the entire intake has to come off as well......

Cheers,

My '83 Coupe has an exhaust leak when I fire it up cold, then it goes away after 2 or 3 minutes. Wazzup with that? Gasket? Cracked manifold?

Most likely it is cracked or failing then seals up a bit as it expands with heat. I gotta say the Haynes manual for this car sucks serious bobo.

Anyway, it looks almost inevitable that the intake has to come off to take the exhaust manifold off....sure would appreciate some insight into this opp. from someone who's already been there as I'm a newb to this car.

Cheers,

early on with my '87 CGT I had a similar problem. Luckily for me, car was still under warranty when it happend (this was a LONG time ago) Turned out to be too much heat build up on the manifold at the back near cylinders 4&5. The manifold was warping and moving away from the head. The fix required removal of the manifold and machining it flat.

best of luck if that is what you are going through. Hopefully you know a good machine shop.

This has happened to both my coupes.
I've seen it happen to 5000s also.
One or both of the studs on #5 ex port shear off, making that cyl. leak.
When it warms up there is enough expansion to seal up the leak.
You will probaly have to pull the head and tap the holes. While you're at it you might as well get a vavle job done!
I currently have this problem on my coupe (for at least 4years!).

Oh goodie! I was afraid of something like that. It'll have to wait till I get the '82 back on the road I guess. And yes, I do know a good machine shop ;0) LOL! I work at one.

I never want to have to do this again! Even with airtools, a lift and any hand tools i needed, it was a nightmare, be prepared for broken studs in the head. Wait till you pull your first power steering rack..... :-)

Its not really that difficult on the non-turbo I5s. I usually pull the head off with manifolds attached and do the work on my bench, then bolt it all back up.

Ach Mist, Furz und Scheibenhonig....

Well forwarned as I am now, I think I might jsut leave this in the capable stud shearing hands of my local shop.....or keep my eyes open for a rebuilt head seeing as I have a bit of lifter noise anyway....

Thanks for the input guys, much appreciated!
