hey Lynn, some great ideas here. intestingly I did notice that the oil cooler was not getting as warm as previouly. Also noted that the engine oil pressure was getting lower when warm. So maybe there is a blockage in the cooler which has caused the oil to get very warm and be redirected through the return valve. This valve exits , as I said, back into the oil filler tube just above the fuel pump, so maybe its part of the problem. The oil relief valve is in a large brass housing which has been soldered shut. I would have to brake this to take a look and there are no instruction in the T16 manual on setting this up. There is a thermost in the oil cooler circuit which could be failed closed but I think it would still allow flow if it has.
By the PCV valve, do you mean the crankcase breather valve as on a Jeep? If so, yes it does have one of these and I have not checked to see whether it is working, having never looked at one, I assume it can be disassembled? Any instructions on how to check it if indeed this is what you are referring to?
