I just rebuilt and I've already posted bout this I was going to try and clean my lifters but I pulled them and rememberd hydrolic lifters duh.well any ways pulled all but 2 and they looked fine but I really dont know what I'm looking for. The "un" mechanics said its normal just drive it it will go away well its does but then it comes back louder so I tried thicker oil(15 w 40 high deturgent)but It got worse I think. I'm just so pissed after sending 3 weeks rebuiding and this stuff happend. If one is gone is there anybody local that will have them (i.e. discount autozone ect)or if 1 is gone will I have to replace rockers or cam. I need some Advice please any suggestions. also it feels like theres not alot of power especially 2-3 rpms is that because of break in or is that the lifter not working right
