I've been slowly bringing a 77 FJ40 2f back to life - I recently re-installed the cam and lifters - reground by the local machine shop. Followed the prescribed break-in procedure with recommended lubes and oils, etc. and 1/2 hour of 2000-2400 varied RPM. Took out for a few joy rides - have about 2 hours total run time so far. The truck runs and sounds excellent - best it's ever been since I bought it. The concern I have is that a couple of the push-rods are not rotating. I've read that this is a very bad sign - indication that the lifters are not rotating and the cam will soon be 'wiped'. I've been advised to just drive it and see what happens; I've also been advised to remove the offending lifters and replace. I've even been advised to remove the cam and lifters and start all over again. And then I was told by a mechanic today that just because the two push-rods are not turning doesn't necessarily mean the lifters below are not rotating. I'm confused and uncertain what to do, so I finally mustered the moxie to turn on this infernal computer-thingie and ask the folks that would know, if anyone does.. I would greatly appreciate any and all observations/advice/suggestions you guys can offer.....
