I have a 99 Formula M6 with 62k on it. I've only had it for a month, and last week it started making a tapping noise. I read all the threads about piston slap, but it doesn't sound like that. Mine is a tick that is always there and rises/falls with the rpm's. It doesn't really get louder or quieter, but it stays there, I also seem to have a drop in engine power as well...Any ideas? Someone give me some advice!

pull valve covers and check for bent or broke pushrods

Miss any shifts lately?

Haven't missed any shifts, but I have hit the limiter a time or two

i have the same noise in my a-4 Firehawk. Been making the noise for three years. I have not noticed any power loss though-maybe the noise is making you think it is weaker. I though that it could be a lifter, however I have had a big cam in the car for a couple of months now and no problems. I think that with an aluminum block and heads these motors will make noises like that just because of noise transfer.

you likely have some bent pushrods.

Thanks for the help guys, it is bent pushrods, got some Comp pro magnums for 99 bucks that are going on next weekend!
