UPdate: I took the valve cover off yesterday and found the camshaft on the intake mani. to be dirty and slugish. Only three of the rear (nearest the firewall) camshaft lobes and rocker arms are slugish and dirty. I am assuming that it is what luke said that oil is not recirculating through the entire engine well??? If so, do i need a new oil pump too (along with oil pan and oil pick up)?
Also, i read an article somewhere on how to bleed the lifters. It said "
pushing down on the back of the rocker arm on the section that rides above the lifter. While pressing, if you feel any movement, you have air in that specific lifter." I tried and i did feel some movement, but can anyone confirm that?
I have some photo and also, you guys think i will need to micropolish the camshaft (on the intake mani. side)?
Comparison of both camshaft:
Now, each lobes and rocker arm of the intake side of camshaft:
How it should be (exhast side):
Thanks guys.
