<VV> serious problem with my turbo engine

[Ulli Dittmar]

first thing is to thank you all - you guys are great.

Here in Germany I am in a lost place with a Corvair - even at an American Car show the told me that a Corvair is not an American car because they did not know it - it might be a big problem to find someone here to get the head rebuild.

Believe it or not - my Corsa Turbo is the only LM Turbo modell in Germany!
54.4 million registered cars in Germany and one Corsa ;-) 

@ savers: they are in place
@ spring can be pushed about 3-4 mm by hand
@ I will take the head off and check what the valve and pistons look like
@ I check with a fiber camera through the spark plug hole - it all looked good

I will keep you all posted what I find after taking off he head

Regards
Ulli the Ba-Vair-ian

> It's bad news whatever it is.  Either the head came off that valve or the seat is gone.  Either way the head has to come off.  You can do it with the engine in the car.  You'll have to start by taking the intake, top shroud and exhaust off.  Then you can remove the head nuts, the pushrod guides, the pushrod tubes and then the head.  If you are lucky the piston and cylinder won't be torn up and all you'll have to fix is the head.  I would probably take both heads off and send them to one of the Corvair shops to have all the seats replaced.  I haven't used one of them yet so I don't have any experience there.  I used to have a friend that did all my head work but he died so I'll have to figure out who I will start sending my heads to.
