carbon deposits

[Deziner]

I pulled the valve cover off of my C14 to do a valve adjustment. There was, what seems to me, a large amount of carbon all up in the air vent valves. Is this typical?

I don't know if I've seen it often enough to call it typical, but I have seen them get pretty dirty. I've had to clean them out sometimes with brake cleaner and toothbrush.

You can block-off the whole system if you want...by plugging the hose, or by installing block-off plates, or you can install No-Flo pins in the cylinder head.

Thanks!  This is the first time I have been inside of one of these engines and wasn't sure what the score was. I think for now I'll just clean all that up. It reminded me of the cross over in the old Small Block Chevy intake manifolds.

Here is a look at carbon build-up inside a BMW 1600. I doubt you'll have this on your connie!

OMG- that is horrible!  What in the world is THEIR problem?  Super rich mix?  Oh wait, the link seems to imply the timing chain skipped.  Yikes.
