I have a problem on my 235 that I need some opinions on. My engine has hydraulic lifters and if I pre load them the engine will miss on #5 cylinder at idle. I have narrowed it down to the exhaust valve. If I run that lifter loose to the point it ticks, the miss will not be there and it runs perfect. I have run a compression test and have 130 psi on all cylinders. I have pulled the lifters, dis assembled,cleaned, reassembled and soaked in oil. I set the preload with the engine running by loosening the valves until they tick then tighten until quiet. Thoughts on this?
