Hello all, i just join the forum after owning my '87 TC 5-Speed since 1989. It has been in storage since 1993 and I have just gotten it running and on the road. I took it to my first car show yesterday. A goal I set last year and made it. I am turning to this forum to answer a question.
Background: When I parked the car it had some issues. The rear brakes where seized and I had a leak at the exhaust manifold and turbo. I had notice that things seemed to be real hot around the turbo and cooked the starter. I thought this was caused by the exhaust leak. A few years later I found the clutch was gone again.
I fixed the brakes and changed the clutch, no problem. I removed the turbo and exhaust manifold. The turbo appeared to be fine, but the exhaust manifold not so good. The threads for the turbo studs where powder!!! It also appeared that one of the holes was repaired at the factory!!! Looked like it was welded. My conclusion is that it lost clamp load and the gasket failed. I had the flange machined flat and had to helicoil the manifold to get the studs to hold. I am going to need to find a new.one.
My question: How hot should the exhaust manifold get? I can go for a ten mile drive and look at the manifold and it is glowing red! I know manifolds can run very warm, but this seems excessive. I believe this issue is not a result of the long nap the car has taken, it was there before. What could I be missing?
Any input would be great.
