Well, I got the exhaust on and was heading back to my grandparents house with the TA and the Girlfriend to pick up some stuff and head back home. Well, half way back (on side roads) I gave it a little gas and the car started popping as if it had a bad miss. It lost a ton of power and now idles differently. When I got it back to the house, I popped the hood and could hear clicking (louder than it should be with Roller Rockers)

My uncle took a look at it and said it could either be a dropped valve or a loose rocker. I was in a rush to get back to work at 5 so I didnt have time to pop the valve covers off. Any guesses on what it could be?

What is the proper way of tightening the rockers? I put the cylinders to TDC and went a 1/4 past from when the pushrod stopped spinning. I have Comp Cams Pro Mag 1.6 RR's so they have little "retaining" bolts to keep them from backing out. I tightened them down as well...

I hope it's nothing serious...

 

If it lost a lot of power you have more than a loose valve. Pull the valve cover.

 

The spin method of adjusting rockers is not the proper method for finding zero lash. Tighten the rocker until the pushrod stops moving up and down to find zero lash, then tighten an additional amount as reccomended by lifter manufacturers specs.

I was using the spin method and got mine way to tight with my Comp 'R' lifters and was causing valve float at high rpms.

You're not supposed to tighten them until they stop spinning. You're supposed to tighten the rocker down until you feel drag on the pushrod. Then 1/4 or 1/2 turn.

 

Did you do headers? Not sure what you mean by "exhaust on". If so, a very bad exhaust leak can give you that loud ticking noise and mess with the O2 sensor(s) and thus cause low power conditions.

 

I had headers on before. I now did a custom true dual system...
