01 Trans AM LS1 noises I have what I call clatter on the passenger side which starts a few minutes into starting the car. It gets somewhat quieter when warmer.
After reading about what people might call clatter, piston slap and lifters, it's difficult to say in words what the sound is that LS1's make. My mechanic says the sound is normal and not which confuses me more-so
I bought 1 bottle each of Schaeffer Moly EP oil treatment and a bottle of Liqui Moly Hydraulic Lifter additive. I am currently running Pennzoil Platinum 5/30 Synthetic which has steadied the oil pressure and is quieter from having Mobil 1 previously.
The car has 98K and looks above average condition wise except for the stress cracking paint on the bumpers.
Which additive would you pick between the 2?

You wont be solving anything by putting additives into the crankcase. Are you even sure that it's valvetrain related? You need to rule out idler, tensioner, power steering, alternator, etc. Have you removed the serpentine belt from the car and started it up and listened to see if the noises went away?

Could be an exhaust leak on your car. i've had ticking noises on my vehicles before and it turned out to be a damaged exhaust manifold/header gaskets. On cold startups you could hear it but then it would get quieter as the engine warmed up. Was an easy fix just replaced the header gaskets and it went away.
I used Hot Shots lifter quieter stuff which had some kinda moly in it and after a few tanks of gas it is noticeably much much the same.
Most of the oil treatments are for dirty engines, mine is very clean which im sure yours is also, it just has bad parts in it so cleaning a failed lifter unfortunately for me and you isn't gonna do anything,

Going to a 40w oil will help quiet the clatter moreso than the additives. Additives have their place, but not as a bandaid to quiet piston slap or lifter bore wear….leave that for the used car salesman.

The attitude the guy posting this thread has I recommend sawdust in the Engine. I feel Maple or Oak will do the trick, a nice hardwood.

You come into a forum with tons of experience that may figure out what your issue is, but you don't want to hear what the cause actually may be because you're focused on dumping money into what unicorn fart might solve your issue.

That's why I call it clatter- whether it's piston slap or lifter tap, etc.

I thought people would share honest reviews of products instead of unending threads describing the noise (which is impossible). These threads go on forever and never reach a conclusion anyway. It's a simple query, have you used these 2 products with any success?

Bottom line- figure out the noise, then either address, disassemble and repair, or ignore and hope for the best. Your call.
I too have heard of Seafoam being used to quiet a noisy lifter but before I'd go to dumping things into the crankcase I'd make sure the noise isn't coming from something external.
Go in with the KISS approach if you know what I mean. Pinpointing noises with a big screwdriver or a piece of garden hose just works!

I'll lay it out- Most folks here don't believe in oil additives, as they are usually only a very temporary band-aid that mask the true underlying problem.

Not me, my dad had his tractor sitting for a couple years and tried to start it. It wouldn't start. I dumped some Marvel Mystery Oil in the gas tank and after a couple cranks it's fired up. Had the same situation with a friends chainsaw not starting. He went to the parts store and got some MMO and dumped a bit in the tank and on the second pull the engine started. Just my experience.
My point is that in a normal engine with a new noise, you figure out what the noise is before looking for a way to quiet it.
Your tractor and chainsaw examples are right on. Sounds like they both had crappy gas that needed something to get it to fire. I would have done the same things.
What the Hell is this?? You ask which of the two additives we'd choose, then say you're not interested in people's experience or opinion of the 2 additives??! Please explain how we're supposed to pick a product without using our experience or opinion of said product! Good luck with what you're trying to accomplish.....Whatever THAT may be....
