whats with the ls1's ticking?

[pimpin78transams]

so do all ls1's have that usual ticking sound? My 02 trans am had the noise so i replaced lifters pushrods and rocker arms but it never went away. Now my 00 camaro has the same exact sound so i assume this is pretty usual? Do any of yall know what it is? is there a fix to it?

I THINK its called a lifter tick for like oil sitting at the bottom of the pan but thats a guess not 100 % on that

Every LS1 I have had (4 of them,one of which new) has had mild ticking on cold start up and quickly goes away after about a minute..

After that,I just here the injectors clicking along... at least I hope it's the injectors!

It is piston slap.Most of them do it.It is not harmful to the engine and I wouldn't worry about it.

I think the Singer Sewing Machine Company, helped design the LS1...

I read on here somewhere that gm had a quality control problem and most of the blocks had a slight overbore making the pistons on the loose side of tolerable but still acceptable.

Agreed. It's called the LS1 "sewing machine" tick.

Just a quick note I was getting same problem un till I switched to an oil filter with a check valve in it it's a problem with some of Chevys motors from a few years back ls1 wasn't the only v8 doing it

[pimpin78transams]

With a valve? What filter did u get and where from? I'd like to try it

my 2002 denali ticks pretty loud i will try your oil filter trick and see if it works. when the water goes down in nelson co. ky. we were hit hard with a flood.
