I tried to fire up the old '51 1/2 ton this morning & I heard a helluva racket commin' from the ol' 216.
Pulled the valve cover & saw 3 intake valves sticking in their guides.
Pulled the rocker arms & found 3 bent pushrods.
I just did a valve job 3 years ago on this head.
& I installed hardened seats.
I use a fuel stabilizer in the gas all the time.
I got lucky & was able to free up all the sticky valves using carb cleaner & PB Blaster .
Didn't have to remove the head. Phew
Does anyone have suggestions on a fuel additive that will help keep the valves from stickin' in their guides ?
A few suggestions I have heard so far are:
Marvel Mystery oil.
A fuel lead substitute.
A small amount of diesel fuel.
I heard " Lucas " makes a top cylinder lubricant, but I dont know if it helps lubricate the valve guides or not.
Gonna drain the fuel & install a set of H.D. pushrods tomorrow, put it back together & start adjustin' the valves.
