I've got one in a '75 245 DL wagon. Antifreeze has found it's way into the crankcase. As I have no garage and it is bitter cold right now here in Wyoming, I would like to ask if these engines have a particular propensity toward cracking a head, or if the head gasket is known to be failure prone, etc. It would be nice to know if there is a "likely" failure before I stand outside in the awful weather running leakdown tests. Thank you, Mark

Hi.
As I've had some B20's thru the years, I can definitely say that one "likely" failure is exactly the head gasket. If Your engine have overheated anytime, You also should check that the cylinder head aligns against the engine body if You opens it. B20"F" is the Injection engine, almost the same as B20"E", but with less compression ratio? Then it's even more probably that it _is_ the head gasket, I would check that out first. Luckily an pretty easy job to do, changing it, as You don't have to adjust any camchains or belts after the change. In my opinion there's a much higher chance that the head gasket is blown, then that the cylinder head in itself is craked, but You never REALLY know until You open it.
Good luck, and tell us what You find out when Your 245 is humming again.

Yes, it is the CIS fuelie engine. The previous owner of the car did not maintain it very well, and it has many electrical problems (including the coolant temperature sender) that I have not yet corrected. I probably overheated it without being aware. I will remove the head tomorrow and inspect. Still, not bad for my guess of a quarter-million miles (odometer is broken at 150,000+).
