<VV> Sound Of Marbles

[Smitty Smith]

Smitty Says;  Mike can't help you with the marbles but I can identify the tarrey residue for sure.  It is a head gasket leak.  May be a very small one but it is nevertheless.  It is the kind that leaks just enough to stink up the heater on initial start but within seconds the gap will close up from thermal change and won't make itself known till the next cold start.  Good source of carbon monoxide if you let it go long enough.
