Thanks to all who responded, special thanks to Steve in GA. Today I was going to adjust valve lash. Started by taking out the plugs, to make rotating the engine easier. Seemed to me they were too tight, especially in aluminum heads.
I used a torque wrench to loosen them, took over 40 ft lbs, except one which was almost loose. From what I've read (gasket type plugs) they should be installed at 18 to 20. Got them all out, no apparent damage. Next, I got a socket on the crankshaft pulley center nut, Although the starter has no problem
turning the engine over, felt hard to rotate. Put a torque wrench on it, took about 80 ft lbs to move it. At that point I decided to have a local shop I trust
to take a look at it, if they can get it scheduled. Will let you know how that turns out.
