my b-in-law blew a t-belt the other day, and his car had been ticking for a couple months anyways.. so i went down and bought the oil pump seals, and t-belts (he's a non car guy)

 

replace everything fire her up and instantly had 20 psi more oil pressure than it used to but the tick was still there..

 

he drove it for a couple days, still ticking.. so i went out and fired her up and punched it to 7500 rpm's a few times and whala, no more tick.. hasn't ticked in a couple days now..

the poor ole car does have 270k on it and is rusted to hell, but she runs good, all things considering..

i had one that just wouldnt go away. sometimes they are just collapsed, or the valve gets partialy stuck open

Standard Operating Procedure all the way.You HAVE to punch it to get the pressure to fill that last lifter in the train.At least all my EA82's were that way.
