Okay, here is the deal. After the Hotcam install (been about 2 months) I now have a fierce upper engine noise. Sounds like a lifter almost.

What i have done so far.

1) Pulled off the valve cover, and done a basic inspection. Nothing unusual.

2) Ran the car with the cover off and pushed on the rocker arms while its running to see when I can get the noise to stop, but no matter where I push at on the rocker arms, the noise doesn't go away at all.

3) Inspected all pushrods, no bent pushrods.

I am pretty sure that I have a lifter that has collapsed on me, but I am not sure how to tell which one or if I can tell which one is done for without pulling the intake (which I need to fix anyways, because it leaks really bad).

Any suggestions??

Thanks

 

You prolly didn't adjust the roller rocker's the right way.. I would start there and also check for header leaks..

Have any sound's or video of the noise?

 

No sounds or video at all.

The rockers I put number one firing at TDC, and then adjusted certain rockers (can't remember the numbers, but I followed the LT1 book that I have). I adjusted the pushrod to zero lash, and then went a little over half a turn.

Then I rotated the engine 180 degrees and did the rest of them.

This is always the way I have adjusted roller rockers and have never had any troubles. Even the LT1/LT4 book that I have tells me to adjust them this way.

Maybe I'm wrong on that, but I dunno...

Anything else to look for??

 

If the car is cold (sits over night) is the tick still there or not till the engine warms up. Where does it should like its coming from. You say its a lifter tick, why?

 

I didn't say it was a lifter tick, I said it sounds like a lifter tick. Its coming from the drivers side under the valve cover/intake region.

It will intermittently appear and go away, which is why I think that I have a lifter that is gummed up and I am going to try and clean it out with some motor flush. Anybody reccomend a good brand of motor flush??

Thanks
