Hi Guys, if you read my 1st post you know I just picked up a 70 Cutlass. I was told the 350 4 barrel rocket motor was rebuilt some 7000 miles ago in about 2003, (I don't have documentation, the engine looked like it was, the owner was a sweet young woman and I'm a sucker) - the car sat for 2 years. There was some left side front valve noise when I looked at it and expected it would go away after an oil change and running it. I put in 10W40 and 1/2 bottle of Marvel Mystery Oil and ran it for about 4 hours - mostly driving and some idling. Valve noise has not changed. I contacted the owner and she is trying to find the receipts. I pulled the valve cover and it was as clean as a whistle with nothing loose, (car has 150,000 miles on it). That's about the limit of my knowledge. By the looks of things these valves are not adjustable. Any ideas or just bring it to a shop? Thanks.
