Need some advice from some of you who know engines. I mention you Pat, because you said you worked on marine engines as well as car engines.

How do you adjust the valves in a counter rotating Chevy 350 marine engine. I know how to do the actual adjustment, I just don't know the sequence. Last night I helped my Son install a pair of new heads on one engine in his boat. (Well, I drank his beer and ate his Doritos, he did the actual grunt work) When it came time to adjust the valves the manual we were using ONLY discussed a regular rotation engine, and it had been very descriptive on everything else up to that point. So, our assumption was that you do the counter rotating one just the same (bring # 1 to TDC, then adjust certain intake and exhaust valves in that position, then rotate it 180 degrees and adjust another group of intake and exhaust valves.

The manual was telling us that when # 1 was up we should be doing # 1 intake valve, and some other intake valves, but when I looked at one lifter it was telling us to adjust, it was obviously not on the heel of the lobe, because the lifter was up somewhat.

What I am asking is, do you use the same sequence for running the valves in the counter rotating one as you do in a regular rotating one, once you have estabished TDC for # 1???

Thanks,

Don
