pics of the teg's innards (56k nope)
 

well i finally took the engine apart on the teg and this is what i have found:



this cylider was filler with engine oil

damn, thats a lot of oil.

^ yeah thats what keeps the engine running

yeah, i know the oil helps, but it is in the wrong places in that engine.

so was it the valve guide seals like i had guessed?

i dunno yet, i haven't taken it apart yet.

I've taken apart many motors. That carbon/oil build up is normal on those cylinders and head ports, especially for an older car like yours.
