Thanks to all who responded to my inquiry. As I suspected, it's a major task.
I asked because when I was recently adjusting the valves I noticed a couple of the pushrods didn't appear to be lifting
as much as the others, probably indicating flattened cam lobes. I don't know what could have caused this, because I
have always fed good, clean 20W-50 oil to this engine (it has about 100K since rebuild). It's possible it's been this
way since rebuild, as I always had lower compression on a couple cylinders (why a reputable cam grinder would screw up a
re-grind is unknowable, but possible I suppose).
I just had the front pulley and timing cover off to replace the cover seal, and had the radiator in and out 3 times due
to water pump issues, so when I get to the cam I'm likely to pull the engine and do an overhaul. The big nut on the
crank is the issue; I bought a 3/4" impact wrench and socket to get it off, but there's insufficient room to get the
wrench on the nut due to the front X brace. I ended up ruining the nut and a new one was $40 from Moss. The new nut was
good quality, but the original had a conical section machined away to clear the Woodruff key, and the new one did not
but seems to be OK.
