Re: Fwd: A look inside 200k mi. engine

["Gary Boyd" <wtirusty@excite.com>]

On my 90Q20v it has just over 300km, the head was pulled at 287 and there
wasn't a spec of carbon on the head, pistons or valves. Compression was well
within spec. I replaced some valve guides, that was it. 
I have used the Chevron or VW Techron additive since new. Guess it helps.
