Hi Guys Ok. Here is the issue. Sticking exhaust valve. Yes I removed both valves. Reseated them. Polish the stem on exhaust valve. Reinstalled all parts, set valves clearance. This engine was rebuilt, with over size piston. Now the issue is,. Exhaust valve pops when running at normal RPMs. I am worried that it might drop this valve. Is there a lubercation additive to add to the oil that could help clean this up? I 've never had a valve stick before. Thanks guys Bill
