Default LT1 with a stubborn lifter tick

My car just turned 70k miles, and has a stubborn lifter tick on the driver side bank. I changed the oil and added Marvel Mystery oil, nothing. Changed the oil and tried Valve Medic, and nothing.

I also had my mechanic reset all the valves on that side and nothing was loose or out of the ordinary. Its not an exhaust leak because i can pin point it by a stethoscope to around the center of the cover away from both headers and injectors. It does get a little bit quieter the warmer it gets, and is obnoxious when cold. No DTCs are being set so i assume its not knock, plus it runs like a champ minus the transmission. lol

How the heck can i get rid of this tick!

Honestly could not think of a better time for a cam swap, consider it a freebee on labor, either buy a haynes book and dive in or pay your mechanic either way it will be worth it.

Agreed. Change the lifters. If you've pinpointed the ticking to the lifters that would make the most sense.

Reads like a lazy lifter. As stated, replace the lifters.

I have a new set of LS7's, but I've read so many threads about people complaining about them. I just wondered if there was a better alternative that wasn't stupid expensive.

The skirt around the roller was MIA when I took it apart. The lifter lost everything from the pin down.

If they're good enough for my 383, they're good enough for what you need.

I haven't read any. Is it the same as the Comp R's where people put them in, they fail and they automatically believe it's the lifter's fault?

Im sure the LS7's are fine. I was just wondering if there was a decent lifter for a little more $$, than I would maybe buy them.

Now the thing is, I have a local dyno day coming up the 17th then Im planning on going to the drag strip the 22nd. I don't know if I want to deal with trying to get the pushrods measured and ordered and everything put back together before that if I put the LS7's in. The reason (a stupid one) I didnt put the LS7's in is because I got impatient and didn't want to mess with checking the length when I did the cam. I really wish I would have just done it right.

Another problem is the PR checker I had would not work because of the guideplates. Is there a checker that will work with guideplates installed?

I know there are a lot of people that just throw the LS7's in and get stock length, but so many people say to check anyways.

Sorry for the

I had the Comp Rs in my car for several years. They were annoying to get set "right", but never gave me any mechanical issues. I took them out last year, however, because even after spending HOURS fiddling with the lash, they were still kind of noisy...
