Greetings,

Well, I hope to be volvo-ing a 142 in the near future; but at the moment I'm trying to figure how to best manage it... It's a 1970 B-20B w/ weber carb and 4-1 exhaust manifold, non-viscous coupled fan. It's got what appears to be a head gasket break: i.e. grey sludge for coolant. But the oil itself looks just fine. I was always under the impression that the "milkshake" mixture would reveal itself in the oil, not the coolant. It holds it's oil, according to the owner. Doesn't smoke either.
Clearly I can't run with that junk in the cooling system, but I wonder if I drain it, flush it, and replace it with prestone 50/50 could I feasibly make a 130 mile run before pulling the head off, or am I towing this thing?(I have enough good judgement to know what the rational answer is.) However, the guy made a 600-plus mile round trip with this sludge, and the water pump is still circulating.
I know this is a stock question but the search function has been reduced to something other than usefull.
I appreciate your sage advice, and hope to be among those with a ressurected 140 soon...
Just talked to him again: says it was rebuilt recently, sat, he picked it up and ran it to death. Sounds like it hasn't been run it right... Is this consistent with the junk in the radiator?
Thanks much,
-Sean
