you beat me to it lol
i believe it is pushrod cup and pushrod rubbing
i have not seen this before,damn did not sleep real good last night
anyway,i checked all the valves with LSM on car valvespring checker there is no binding of the valves in the guide or seal squeak
removed rockers and pushrods and inspected,i can not see a problem anywhere,checked interference of pushrod,intake bolt etc all good
i then proceeded to put some extreme pressure lube on pushrod tips
noise pretty well gone
cranked engine over on the key with sparkplugs out to get oil up top,takes about 15 seconds
let sit for a minute noise gone
let sit for ten minutes noise back
conclusion-yes it is the pushrod cup
is this a problem?
i am hoping not but any thoughts appriciated
