The lifters bleed off quickly and I wondered if anyone else has had problems with their lifters and how they resoved it? I have a high pressure oil pump. The solid pushrods were also bought from CompCams. We have checked everything possible, including another oil pump, and the clatter still occurs. CompCams said the lifters oil through the lifter band but not sure how that would happen as there are no oiling holes. Educate me please.

Some Comp hydraulic cams have aggressive ramp profiles that will always make noise no matter what you do.

If there are no holes in the body, how is the hydraulic lifter getting an oil supply? I don't know if these are the Comp hydraulic rollers you are using but I see a hole. https://www.ebay.com/itm/COMP-Cams-Pro-M...2-/392188611229 "We live in a time when intelligent people are being silenced so that stupid people won't be offended".

Two images added just for reference regarding possible location of the feed hole. Last edited by Transman; 02/01/19 10:08 PM.
