No - something got between the valve seat and valve. I did not have the rocker in at the time. I think while I was tapping the valve washer to break the keepers loose a peice of carbon lodged itself there. running the car cleared it out.

Thanks for the offer. Very interested in seeing if I can figure out why your 1G lifters were noisy and mine are whisper quiet. PM me with your PayPal account so I can at least send you some $$ for S&H.

No problem there - send me your address I will ship them out. (don't worry about shipping)

This is my thought - The lifter "pumps" up until there is enough pressure between the rocker and the lifter that there is minimal oil flow though the top hole. Now if the top hole gets plugged it thinks it is already pumped up even though it is not.

They where hard - the exaust ones where worse than the intakes but if you would squeeze them in your finger they would keep that shape. There was little to no friction between the valve stem and the seal. I am sure the back bank will be worse as the temp gets higher.

Mine was pretty dark - i am color blind so it is hard for me to tell.
Did you get my PM with the pictures?
