Can someone please post a picture of a "Toyota" head gasket (new or used) for a 78 2F. I ordered a gasket and am not sure if I received the right one. The gasket I received seems to be missing some water pasages.
Do you have your old one to go off of? I went through the same thing just a couple months ago. The My old gasket (aftermarket) had a bunch of coolant holes blocked off, I ordered a new ITM (OEM) and it matched the old one. There was a number of passages blocked on one side of the head/block but I haven't had any sort of problem.
Did you order yor new gasket from Toyota? The OEM for a 2F will have copper reinforcement around the oil passage hole. Very important that you put it on right side up so as not to cover this hole. I wouldn't use anything other than the Toyota gasket.
The old gasket was an aftermarket gasket. So that is of no help.
I ordered the gasket from a vendor that quoted me twice that it is an original Toyota part. It does have the copper "ring" for the oil feed to the rocker shaft. But I had the understanding that any gasket surface that "touched" oil was copper ringed on the Toyota head gasket. The gasket I have only has the one copper ring. My big concern is the blocked off coolant pasages.
