help identify tick after mods We have a CTS-V with a LS6. I put a comp cam in it, new timing chain, had the heads ported and bigger vavles installed, also milled the heads 30 I believe. I went with 7.35 pushrods. Also addeds the patriot spring kit to the heads. we have a tick on the drivers side now that is pretty loud. When its cold and has been sitting for a couple weeks it is silent until it warms up. We also put full length headers on it so I know this enhances sounds but this is definitely not a consistent sound.
so far the possiblities we have are:
-Lifter
-I was told today possibly the oil pump o-ring
any other suggestions or thingsn to look at before I yank the heads back off? I can get a video of it if needed...just looking for any advices or help before I spend a lot of time and money for nothing!

make sure the header bolts are tight as well as where they connect to your x-pipe. On my Camaro if my ypipe is loose at the back of the headers I'll have a slighly louder exhaust. If the headers are loose at the flanges I believe it is possible to get a ticking noise in that area too

I did put it on a lift and check the collectors and they seem ok. I will try to check the headers tomorrow, but I think they are all good. Also, the tick doesn't do it when its cold so I feel like it would do it all the time if it was an exhaust leak, but you never know
try to get a small mirror from a girl for make up and put it along the header flanges and if you see a spot above a port with black(I guess carbon) That is an exhaust leak. I had one of these on my car when I first installed my headers. take a Cresent wrench to tighten the bolts. That's a pretty easy way to do it.
could be something else too. Hope not.

was going to wait until you come by so you can hear it at the same time.
this is an old video but it is decent enough to get the idea of the tick...just seems to be the drivers side. I will get a better video tomorrow.

Check for a loose spark plug. I know, I know, probably not. But, I was convinced I had a lifter or rocker going bad and it eventually turned out to be a loose plug. Cheapest, easiest fix you'll ever have. Also, make sure your plug wires have a good, tight fit. You might be arcing some. Check at night for any sparks in the dark. Good luck.

last night we checked plugs and exhaust. we know its not a exhaust leak.
We put 7.4 pushrods in the drivers side (where the tick was) and it is gone. we only let it run for 5-10 minutes and haven't driven it but it sounded fine. I will probably do the passenger side today and give it a try. I am still not sure why it was only on one side but it seems to be ok so far....

Something about a Caddy loping like that just makes me
Maybe it's because it make me think of my grandma when she still drove. She did drive like a bat out of hades though and prolly woulda liked a cammed CTS-V
