I finally got my rebuilt 2F back in my 86 FJ60 and got it running today. The bad news is it is leaking oil badly from the front timing cover. A drip a second at least. This is deja vu for me. I had the same machinist rebuild my 2F in my FJ40 and it leaked at the timing plate/cover. He made the problem on the FJ40 motor good by knocking $420 off the rebuild of the FJ60, (which is what I paid a local mechanic to fix the FJ40 Oil leak). Other than the oil leaks, the motors are running fine. The machinist has been recommended to me by two major car dealers and I have seen the souped up race car engines that he builds, but obviously he is missing something on sealing the front end. I have the 2F engine repair manual and there is mention of applying liquid sealer to the lower 2 bolts (bolt A). Could this be the secret? I would appreciate any comments on your experiences with oil leaks in this area. Right now, I feel lower than whale s**t.
