Thread: *350 sbc Valve Ajustment*

I agree with Denny. I wrestled with this a long time. Found out of 1,000 videos on you tube, 999 were wrong. The advice above is spot on. One thing I would do and you may not like it, is pull the intake, the push rods and the lifters, check the pushrods for straightness, check the lifters to see if one is excessively worn. I would also check the valve geometry and the rocker arms plus the rocker arm studs. The reason I suggest this is the lack of success you are claiming using reasonable techniques. If something is worn ie cam lobe, push rods, etc. it will never work out. Another suggestion is to look up Blackstone Labs, get an oil sample test kit and send a sample to them. They will tell you straight away, normally in a couple of days, if there is some excessive wear in your valve train or components. The solution to mine was replace the lifters, push rods plus the rocker arms, and rebuild the engine which was full of metal shavings. The advantage was by catching it I was able to not destroy the engine. The rocker arm studs were screw in so they were okay but I did replace the locknuts. At the end of the day the solution was to tighten them more than I thought because of my inexperience. This is just an opinion with an objective to support what the guys above are saying. It was only my experience.

Ok guys.....here is the update on adjusting my valves. I adjusted the valves per the procedure below. I set both the intake and exhaust valves at .020 cold. I'll be damned if it don't run like it did before I started adjusting the valves. So far I am a happy camper. I let it get a little warm and took it out for a run. I didn't get on it to hard but man does it pull and sound like it did before. When I got back I listened to the engine and like before it has some engine noise which now since I know it's not hydraulic I'm fine with it . I did hear something on the right bank that sounded like an exhaust tic. I'll investigate that further tomorrow but for now I'm satisfied. Thanks for all the input.
