Just got my car out today and its making a weird chirping/ticking noise which sounds like it is coming from the valve train. Could this be my s/a rockers not being adjusted correctly? Its not loud enough IMO to be a spun bearing. The car still screams but I'm just curious if anyone has heard a similar noise and figured it out? I am by no means a mechanic but I did make an appt to have the rockers adjusted Thursday at noon. Any ideas appreciated.

 

I use a mechanics stethoscope to pin point the noise. I have noisy valve train and sometimes you can adjust to get it to go away.

 

Well I found out what my issues were. Apparently the lock nuts on my 1.6 rockers are hitting that back side of the rocker body. I also have at least 4 lifters that aren't loading up right. I have the comp hydraulic lifters now and they have under 2500 miles. Are these things junk and what are my options as far as a better set goes? I would think for over 200.00 for these lifters that they shouldn't be failing with only 2500 miles. I'm really f@#$ing irritated right now. I have too pull my intake for the 3rd time now and am sick of working on this thing.

 

Ive hear hit or miss stories on the comp lifters.

have you thought about trying the GMpp ls7 lifters? they are like 170$ for a set. if gm uses em in their ls7's and they are universally used in all lsx motors they must be good.

 

There's a "sticky" at the top of the "LT1 Based Engine Tech" forum topic listing regarding the Comp lifters.
