Upon cold start I have a tick, but its only noticeable after the car is running for a minute and when the RPM drop from 1000 to 750. Then it is noticeable from around 2000 - 3500 RPMs when accelerating. Not piston slap or anything that moves the car around or is too loud. Just an RPM-Dependent tick of sorts. Over revved once when shifting from 2nd-3rd and missed 3rd (way back when I first bought the car and thought I was hot-sh*t). Other than that, never anything higher than about 5900 RPMs, and that was strictly racing. Usually power shift under 5000 if I feel like getting on it.

 

Oil changed every 3000 miles and no recent traces of metal in old oil or on magnetic drain plug.

 

Had the same problem years ago on a old Fbody, stopped using Fram filters and it was gone.

 

I use Mobil One Synthetic 10W30 and Mobil 1 Truck filters (longer, more capacity). Never use Fram, never will. lol

Check oil every week at least. Maybe have to add 1 quart between changes (3000 miles or 2-4 months depending on driving). Fairly normal from what ive read and experienced. Cars tend to burn oil eventually, especially after sitting and this babe sat for over 6 years.

 

Just telling you my experience, my sound eventually went away after the car was warm. All earlier LS's seem to burn oil. A lot of guys had a ton of warranty issues with this back in the day and GM said it was normal.

 

Yeah. It does go away pretty well when warm, just a little more prevalent at times than others. And yeah, burning oil is normal. lol

Thanks for your input Monmouth, I wasnt bashing you or trying to argue.

 

Use fram filters all the time and never had a problem or any ticking. I would check for an exhaust leak.

 

Could just be a sticking lifter or 2. Rislone is a good product. I've unstuck many lifters with it. Wouldn't hurt to try anyway...
