HELP I been noticing a loss in power in my car i just got done putting in a new short block but i used my old soild lift cam in it at first it was running great but the last month i been noticing a loss in power. So last week i was going down the road and it started making a poping sound and the oil pressure was going down a little bit i took off the valve covers off and turned the motor over by hand and about 3 or4 CID.the valves are not opening i can see the other valves open and close but on these CID.the rocker arms dont go down, So i ordered a new cam and lifters BUT do you think that the wiped cam would efect the oil pressrure, Thanks for any advice Ronnie
