[Vwdiesel] cleaning carbon clogged rings without disassembly

[gary]

$100 head gasket for a 1.6NA?

Is it gold plated or something?

I have never spent more than about $20 for an OEM head gasket for any of
my VW diesels.

Runaway aside, you can just run the engine with a synthetic and a
"sticky ring" additive. I'll bet that if you run the engine hot and long
enough, things will loosen up on their own. But letting it sit for a
while with a good solvent in the cylinders would be a good start. Just
make sure you clear out any of this volatile liquid before starting.
