hey guys i am still at a loss as to what my problem could be still. went outside to start my car it started rough then died started it back up and went maybe 200 ft and the rockers started clacking so i shut it off and pulled the valve covers then started it and saw i had to oil up top. i put cleaners through it, new thinner oil and i have 65 lbs of pressure which i checked on a mechanical guage. i pulled the intake and all my lifters pushrods and rockers are fine as well as the girdle which holds the lifters in. the oil pump shaft is fine that runs off the cam. im about ready to pull the motor and tear it apart. its a 96 lt1 trickflow 21* heads cc306 cam ls7 lifters stock length pushrods 1.55 roller rockers. this motor was freshened up with new everything about 5000 miles ago it was built, it has been running for a year without problem now this. if anyone has any insight on what i should do or has had this problem i would be grateful. i was told by the shop that did it that possibly one of the caps above the cam came out but to check that i will need to pull my whole front of the engine apart and if it isnt that it would suck to waste all that time. thanks in advance guys
