On my way home from the track last night, my car started making a tapping noise, like you would hear from a bent pushrod. It started kinda faint then just got louder, wtf. I pulled over and listened, but could not make out which side it was coming from, sounded more from the manifold to me. I shut it off for a bit, then when I first started it, there is the loud tapping sound, then it got quite after a few seconds. Once I get the rev's up a bit (back on freeway), the loud tapping comes back again, from faint to loud. I'm just thinking the lifter might not be pumping up at higher revs. I think if it were a spring or pushrod, the noise would be continous all the time. What do you guy's think it could be?

Thanks for any help...

Any sounds at WOT while going down the track?

Sounds like lifter / valvetrain problem. <img border="0" alt="[whiner]" title="" src="graemlins/gr_cry.gif" />

Sounds like pushrods but first check the spark plug wires. Then trouble shoot from there.

I don't think it made any noise at the track but it's hard to tell with the cutout open and a helmet on. It definately sounds like a lifter/valvetrain problem, but the funny thing is, I let it get nice and hot in the driveway today, rev'd it to 2k for a while and no tapping noise. I need to take it out for a spin to see if it comes back. I double checked the spark plug wire's before I went to the track. There was no power loss or anything, car ran good, just that aweful loud tapping noise...

i noticed a reallly faint ticking from inside the car lately. i dont know if it was always there or if it just started. do you have a cam/stiffer springs? it almost sounds like when you leave a window open a little, like a whoooosh, but a tap sound, if that makes sense. sound like what you hear?

No, that's not what I hear. Mine is very distict in sound and definately coming from the valvetrain. I do have a cam and springs BTW. Thanks for the reponse! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> .
