Not the first time out. Been running it all summer, but I'm pretty sure (in retrospect) we've been getting some reversion all year.
Didn't get around to putting on the new drive as this happened. Hopefully test both this weekend. Looks great though. thanks

Good luck with it all. Sounds like something has changed recently. If it's the same set-up, the water is getting in somewhere. Keep us posted.
Your welcome!

Yes, wet Stainless Marine which is why I commented here. Something just does not sound right. What are the cam specs? At a 114 deg lobe center it would be hard to achieve reversion on any reasonable cam. Maybe the cam specs are incorrect???? I know I'm reaching here and I'm positive Tyler checks all the cams when indexing but It's a thought.

A cam timing issue can cause this. Either from being improperly installed or loosing a bushing or something like that. Another thought is bent exhaust valves. You did mention popping. I think I would do a compression and/or leak test.

Judging by the water I was getting out of the O2 sensor hole, I would have sworn there was a leak in the exhaust, but Tyler said he pressure checked them and they were fine. I checked the O2 bung in the tailpipe and it didn't leak either.
