No steam from the exhaust, no water in the oil. The engine runs really well, averaging 7+ MPG and can pull mountains with relative ease. The engine holds a solid 50PSI oil press. at cruise and about 30PSI @ 600 RPM idle. My mech tells me to inframe it, he can replace the head gasket for alot less than inframe, but tells me it is wasting money to do the head gasket and not inframe it, since it is already apart. What would you do? 920K is pretty high, but man it runs great other than losing coolant. !!
the worn liner walls will be very visible once the cylinder head is off...
920K? it's due
