Cylinder head noise!

Do you have a camera with sound to record the sound its making?
otherwise you may want to try bleeding the lifters.

I do have a camera that does all that but cant get my computer to read the disk anymore.... :(

shawn ( 4seasons ) came over and we used a stethoscope on it and the noise is deffinetly coming from the head.. Its on the exhaust side by the cam gear.. or thats where its the loudest...

Tested it under the car while running and even with throttle and nothing from the oil pan.... Might be a lifter or rocker but im going to take the vc off again tomorrow and see if I can wiggle any of the rockers.

I took the valve cover back off and all the roller rockers are nice and tight along with everything else...

Still hoping for it to be collapsed lifter...

I would take all of the lifters out and bleed them with new oil. Its quite easy to do. There is a post on dsmtuners on how to do it. after you do that the knocking will be very loud for 10-20 miles but will quiet down eventually as they are filling with oil.

Also ecmlink shows no knock untill driving and even when im getting into it a little bit "not much" it shows a max of 1.7 and it still needs to be tuned

realistically you should just replace the lifters. you should always put in new lifters when you put in new cams but bleeding them would at least be a good place to start

Why would you need to put in new lifters with new cams? The lifters don't touch the cams.

Ok, who gave this kid rights to post in the tech forum. The only reason to replace the lifters is if a) you have a collaped one. or b) you have the 2g lifters that "tick" in which case replace with the revised lifters.
No reason to replace when replacing cams.
I sent him instructions on how to bleed the lifters (evom how to). From the video he sent me it sounds like a bad lifter tick, But if bleeding the lifters or changing to revised lifters doesnt help i would definatly pull the oil pan and check the rod bearings.

The noise is definatly coming from the head, I dont think he has to worry about any lower end problems. I heard it in person the other day and its for sure in the head.
