The early 2F engines had domed pistons and the castings are much thicker than the later version found in the FJ60 etc. with the flat top pistons.wesintl said:Loosing antifreeze and having milky oil cap could be a headgasket but I'd suspect it's a cracked head. Those dome piston heads from 79+ and 60 series don't have all that great a reputation. You'll have to have the head off anyway to replace the gasket but I'd start trying to round up a head if i were your. I'd forget all the testing and pull the thing your going to have to anyway. Or since you have a known 2f just swap it in.
Hope it's not and good luck.
Yes, all the E-7/80 2F open chamber heads are interchangeable. There are only two casting numbers, IIRC, 61030 and 61031 for those years.RIDDLER said:Truck has only sat for about 20 days after the PO said it stopped.
FYI- The good engine is from a 1975 FJ40. is the head compatible to a 1979 block?
