I have my first track day with the Elise on Monday. During the tech inspection today the start of wear on my 3rd lobe was discovered. Is there enough life left in the cams for a novice track day at this point or should I play it safe and bail?



Another option might be to disable the second cam if there's an easy way to do that. It might not be a bad idea anyway since I'm a noob. Is there a way to do that?

BTW 2005 / 21,000 miles / no track days / one autocross. I'll post engine # in other thread later.

Did the guys in Waltham happen to see this? If so, what did they say? Also, did you happen to hear any unusual ticking? Sorry to hear about your problems. I forget my engine# and I have not checked my cams yet, but I know there are cars with this problem with engine#s below and above mine. :(

If you can hear the cam lobe and follower ticking like a collapsed hydraulic lifter on an old pushrod american V-8, I wouldn't chance it due to the pounding you will be placing on that valve. If the valve train is still quiet, I would think you should be able to run the track day without further damage to the valve train. As always, YMMV and if you do run the track day, keep an eye (or an ear in this case) on the worn parts.

Hmmm...cylinder three...where have I heard that before? :rolleyes:

Sorry to hear that, Keeper. Anyone who starts an (THE?) Uberpost doesn't deserve such a fate. :) Please keep us posted. I'll add your name to the list if you think that is warranted. Or just post in one or more of the threads in question and I'll do it; include your build date, too. Had you gotten a CEL yet or did you happen to stumble upon that?

I strongly do not recommend tracking the vehicle.

My experience is as follows:

On track - limp mode - code P1301. Serviced and theoretically "repaired" several times, without the true problem ever being discovered. I would be told it was fixed, and go to the track to have the same issue again. I think I just made it worse and worse, and by the time the cam/lifter problem was discovered, I needed a whole new engine.

Right now you can probably get by with a cam/lifter replacement. Don't risk it getting worse.

Just my humble opinion,

No ticking. LMS didn't see it.

No CEL. Found during tech inspection. I'll get my info to you.
