Before you take the time to check out the plugs, drain your oil into a bucket and look it over. That would take just a few minutes. If you have debris in the oil....

918s. I hope they weren't one of the faulty batches. They were manufactured in May 2006.

Crap, I did a search and there were all kinds of failures from 2006 valve springs.

Almost sounds like a converter problem. Maybe the clutch locked, and fragged.

how do you get away with a stock tranny with a radix 6.0 when mine starts slipping with just a 6.0? lol

Hook up your tuning software and see what codes are showing.

No trouble codes, other than the usual O2 sensor and speed sensor codes that have always been there.

I haven't felt any slippage, but it could be. I don't have much experience with transmission problems.

My ETs suck because Temple Dragway is absolutely horrible for anything but drag slicks. They had a Viper and Z06 running high 12's/low 13's last weekend.

Thanks again for all of the replies. If I don't find anything broken in the engine, how do I check the converter?

put it in nutral, and take off the drive shaft from the trans . . . it "should" turn over by hand. Other than that I have no other ideas on how to "check" it.

pull the pugs and put a wrench on the crank . . . see if it spins over.

Are you sure that you didn't break a belt ?

So... the first Comp 918 valve spring on the #7 cylinder broke along the topmost coil, dropping the valve into the cylinder. The spark plug wasn't damaged, but I didn't pull the head off yet to see what kind of mess there is.

I don't remember the spring batch#, but I remember the julian date showed them manufactured in late May 2006. They had a blue or green stripe. It was hard to tell which color it originally was, it is kind of a shade in between the two.

Anyone ever dropped a valve and NOT have catastrophic damage?
