i must be blind but I don't see any cracks??

I check mine every 30k. 30k is a good interval. Unless something changes with this turbo car this weekend

Each customer has had one inspection along with the custom VA. Basically, ever car that has never had the cover pulled by me gets it pulled for VA and RI (retainer inspection). If it has been done be me once before, it has never been re-inspected.

UNLESS someone has over-reved, or think they have. I'll inspect the retainers, but never re-adjust the valves. Not needed.

My recheck interval is 80k, based on my car. The VA has held it's settings for 65k miles.

I have learned that once they crack, it's a slow process to get as bad as these.

Never found this on AP2 of course.

Billman250

Correct. The cracks you can't see. But the recessed keepers are very obvious if you know what you are looking at.

Thanks for the reminder here's the underside of the worst one from tonight...

Thanks Bill. Your growing experience with the S2000 is absolutely priceless.

Just to familiarize with what you see in the above pics.....

great picture billman. to check it, all you do is take the valve cover off?

aero3685

Yes.. to see them all you have to do is take off the valve cover, but you WILL have the rocker on top of the valve stems, so you have to kinda peek around/under them to get a good view.

Thanks again for everything Bill, I just got home but the ride back was great. 9000 RPMS through the Queens Midtown & Lincoln Tunnel woke me up Dont forget the retainer that was cracked in 4 places .

Bill, have you heard about the new forum some of our moderators are putting together?

It's going to be for new and prospective owners, and contain stuff they need to know. I think you're pictures need to be included, and you might be able to help the moderators write up a paragraph or two explaining what we currently think to be reasonable and prudent inspection intervals, etc. Might also want to mention the Modifry Shift Beeper and it's peak RPM memory, which is a sort of "inspection needed" indicator.

Certainly nobody is more qualified to discuss this, and your pictures are almost essential for any explination of what happens and what to look for. Maybe you should contact the mods and offer your services.
