Subject: 1978 SLC noise
Question
I have a 1978 450 SLC. It has upper engine noise. (clattering). I removed the Cam Covers and discovered that everything is clean. The dipstick shows clean oil, as clear as new.The oiler tubes are clear. The plastic fittings are intact. I removed the Oilers and there is no oil coming from the holes in the side of the cam bearing supports. The rockers are all loose when the cam is off of them. It seems that all the lifters are collapsed.
Is this a sign of the oil pump not producing pressure? I find it difficult to believe that all 16 lifters are out at the same time or that all 10 oil passages are clogged at the same time.
What do you suggest?
Answer
what does your oil pressure guage say in the car at idle?
Clatterring at start up would suggest timing chain issues. How many miles?
Have the valves been adjusted to spec?
have you visualized the cam lobes and oiling process through the oil fill hole?
Let me know
Ron
