Since I am again being lambasted for warning you all about defective -
i.e. rocker arms - that will damage - destroy your engines :
let's try another valve train part = pushrods.
Engine Push Rod 1960-9 Corvair All Applications.
ref. GM Gp. 0.426 Rod, Valve Push # 3839661 5/16" Dia. Length 10 9/32"
one piece construction with formed ends @ 22 grams ea.
First appearance 199? ; when TRW & Sealed Power were merged by Federal
I was sent a bunch of Sealed Power # RP3077 two piece pushrods @ 43 grams
instead of the usual ( at the time ) TRW # 48017 three piece @ 45 grams.
Last check - the problem still has not been corrected.
I am not sure of true mfg. so I will just refer to these as SP Sealed Power
The SP's are readily identifiable - visually by the silver oxide portion (
the valve spring end ) joined to the much longer black oxide portion. The
problem is at the "joint" - located at the guide plate - when the pieces
were joined - the diameter was ever so slightly "ballooned". In any use the
pushrods will wear rapidly and fail.
Simple test if yours appear as such - silver & black - carefully check for
clearance at this joint thru a guide plate.
Be aware - be warned !
