- Hi,
-
- My 1985 S-15 GMC Jimmy (2.8L V6) has been using about a quart of coolant
- per week (approx. 200 miles) for the last month or so. I'm thinking
- head gasket, as I'm seeing gas bubbles in the coolant in the radiator
- and not finding any external leaks (there's also no coolant in the tranny
- or engine oil, so I think it's dropping into a cylinder and burning).
- Its got 94K miles on the original motor, which seems to be in great shape
- otherwise, but all those years of lugging around with the *!^%700R4 auto
- have probably overstressed the gasket.
- Anyway, I was wondering if anybody had any experience they'd like to share
- on this. Specifically, any idea how long I can go before the gasket really
- deteriorates? Assuming I need to change it, should I do just the offending
- cylinder bank, or should I do both? Good idea to do valve seals on this
- motor while I'm in there? Any things I should look out for? Thanks for any
- help!
