O no... Bad tapping out of nowhere!! Well I drove home from work at 5am and everything thing was fine. Normal driving no high reving or anything. Then I crank it up at 2pm to go back to work and after about 2 minutes it sounds like I have an exhaust leak. Then after about 10minutes of driving it is tapping like a mother f'er. Slow tap at idle but still loud, start to excel and it's alot loader and goes faster with rpms. I'm taking the valve covers off tonight just thought I would see if anyone has had this happen. I did a search and just saw like over reving stuff. Mine just started on it's on.

Do you think that it could be an exhaust leak? Maybe a blown exhaust manifold gasket. Try to isolate the noise first by careful listening. Use a piece of hose held next to your ear and see if that helps you track things down better.

It's not an exhaust leak...I could tell that before I even popped the hood. Sounds like a really loud lifter. But I havn't pulled everything apart yet. Going to tonight after work, it's gonna suck. I get off at 11pm and then have to do all this and be back in at 10am and work till 11pm. ahhh. damnit...
Hmm, I only glanced at the oil pressure it seemed normal I'll have to check again.

tapping mine did this same thing about a year ago, on the way to work it started tapping sounding like a exhaust leak around the header, i got out and checked and listened, around lunch time i went to eat and it got worse and started ticking louder and increasing as the rpm went up, on the way home it got real loud and loss power for a second. i thought it was a bent or broke pushrod, so i dug into the motor starting from top to bottom, after checking everything it came down to the bottom end, the number 6 rod bearing had spun. i assume it lost oil pressure at some point but in the end thats what happened to mine. hopefully you have a exhaust leak or bent pushrod or loose rockers or loose anything besides it being a spun main or rod bearing.
good luck man

it might sound stupid, but i had that ticking sound too, exhaust leak. so i got under the car to look at my clamps where i hooked the duals up to the headers cause i figured i bent it out of shape when i scraped my pipes a few days before. couldnt find any leak so i started checkin the header bolts, come to find out #8 plug was loose. It sounded like it was coming from within the motor and resonating thru my headers. so maybe check that?

Used a stethescope(don't know how to spell that) last night, sounds like the #8 and it is louder the closer you get to the inboard side of the head/valve cover(closer to the intake manifold). So I'm guessing bent push rod at the most. I hope. And oil pressure is normal. guess I'll find out this weekend when I pull it apart. Please just be a loose rocker arm or bent push rod... 
O, and to answer your question, I didn't have any missfire problems with mine.

Definitly found the problem. Snapped a push rod in half some how. I have pictures but it says they are too big. Guess I'll put them on yahoo pictures and post a link. They are probrably going to look like crab though cause yahoo is going to majorly down grade them. And it was one of the rods from #8.

your still driving it? mine was parked at a friends about 5 minutes after it started making the noise and you see the damage. Driving on it would be horrible. But good luck hope it's nothing major. I'm glad I didn't take mine to a shop, only took about 45 minuted to remove everything and find that rod.
last week. Good luck

I see why it's going to the shop no
To answer the other question, It's really easy to get to. I took off the coil packs, and that wire bundle that runs to them. Unbolted the valve cover pulled it off. Since I knew the sound was in the back I started there when pulling the rocker arms off. Pulled one(undo one bolt and the rocker comes right off, very easy) Then you can just pull the push rod straight out of it's hole. Simple. Make sure to torque the rocker arms back down. 22ft lbs I believe. If you don't have a torque wrech just rent one from autozone. Took me about 30-45min maybe less.
I thin I might have to order one nobody around here has one. I think they are like $7.00 a piece or something like that.
