Just curious why my exhaust chamber looks like this? The other head looks clean in exhaust chamber. Is this what it looks like if you have bad seal or guide? I have been trouble shooting some problems as noted in another thread and noticed this on disassembly. Any ideas?

 

Looks like you may have an exhaust valve seal seeping ..

 

Looks kind of wet down there, doesn't it?
Something is amiss. Could be a number of things.

 

Looks like a bad valve stem seal.

Is the valve stem all crusted up above the guide?

 

Yeah it is.
