piston slap..... very common and nothing to worry about. Not sure you can quiet them down.

Some people claim the German version of Castrol oil will help quiet it down, ..., some claim that Lucas Oil Stabilizer will, ..., I don't think there's anything you can really do but live with it & wait for it to warm up.

Read all about it your 'LS1 Piston Slap' search.
There was a group lawsuit about it at one time many years ago.

It's Funny since Tick Rebuilt my Top End it no longer Ticks. Must be the LS7 Lifters and New Push Rods and cam. Sort of a play on words.

The stock lash on the rockers may have something to do with ticking. Changing up the push rods could potentially tighten it up a bit, but I wouldn't suggest that on a stock cam/spring setup. If it's not "broken," don't fix it.

It's just a heavier oil, but without the additives of a motor oil. So when it gets hot, it froths up. Not something I'll put in my engine.

I purchased a 06 silverado with an lq4 motor in it and I could tell it had been a while since the motor oil had been changed, it was extremely black and smelled burnt

I used the Lucas oil stabilizer on my first oil change to get everything copesetic after having such old engine oil

I did not notice any difference in terms of engine noise. The ls1 motors have loud top ends no matter what oil you use. When it's a metal on metal contact oil viscosity will not change a noise to a greater extent

When my engine is cold started it makes a lot of noise for the first minute and a half then the piston slap noise goes away. Once it is warmed up it stays quiet for the rest of the day. It has been like this it whole life. I have 250,000 + miles on the original short block using Mobil 1 10-40. The car is a heads/cam and all the bolt ons dailey driver making 452/418. The oil and filter changed at 5,000 mile intervals. Oil consumption has been 1/2 quart every 2,500 miles since the car was brand new. The only way to cure the piston slap problem is to use new pistons. LS series engines are notorious for their piston slap on cold starts. But if maintained properly they can have a very long life span. I had the heads off at 228,000 miles and you could still see the cross hatching on the cylinder bores. I have learned to just get used to living with the piston slap racket over the years. I have always run dual valve springs and have never broken a spring. I like to think that by letting it warm good before driving it has been benificial to the engines longivity and the life of the valve springs. So there seems to be some plus side to the LS piston slap over the long run...
