Exhaust valve leak

[JAWS]

My engine fires up and smooth. No morning sickness. That's why I believe my mechanic said fly it ain't no problem yet. No morning sickness and have had no other issues other than leaky exhaust valve on a cold soaked engine. He agreed if it's decent now it will be better when hot. That's why he said he is not worried yet.

Sounds reasonable to me.

Not my problem until I see or hear about an issue.

owners, what can I tell ya.
some are very pro-active, others aren't.
most of my owner customers do a 25 hour oil change and engine inspection.

I change oil at 25 hours or 4 months which ever comes first. Always and I always cut and inspect filter and send off for an oil analysis. Have been doing that 4 years.

I've been turning wrenches and building car engines since I was a teen. So I'm no stranger to it all but with planes I'm waaaay more cautious when stuff doesn't seem right.

FWIW, I have a bad cam, oil analysis was normal and filter always clean. It was my engine monitor that was first indicator of a problem.

I may have missed the entry, so I apologize if this has already been raised, but what about doing the Lycoming valve wobble test (SB-388c) as a direct way to determine the degree of valve guide wear? Isn't that what the test was put in place to do?

It's a tool in the valve troubleshooting kit that should be used.
