i got 2002 Z28 LS1 with 17K miles on it. and every time i look at the engine after i start it, the engine never stay still, it would shake a little constantly.
is this happen to all the fbodies cars? or is it something wrong with my z28?
and i also heard a strange clicking-ticking sound from the engine.
any ideas? (this is stock LS1 z28, only intake, thermostat and cutout mods)

thanks for the info. in advance.

Shaking is normal, dont worry about it. The ticking is probably what we call piston slap.

my engine shakes too, of course it might be because of the cam haha...

my engine did the same thing as you described and it turned out to be one of my spark plug wires was arching and fouling out. i went through and put some msd wires and ngk plugs on there and it runs as smooth as ever. If your car has the stock wires on it you might consider checkin that out. Your car, having only 17k miles might be something else but it would definitly be something to look into, its not enough to trip the "check engine" light but enough to worry about. I was very relieved that it wasnt something major after it was all said and done, although changing plugs and wires left my engine with a nice coat of knuckle blood. hope this helps

you sure it wasnt stock before the guy sold it. if it isnt a plug, it could have a mild cam in it.

my engine rattles the entire car right now... though the 382 may have something to do with it

Yeah, that might have something do with it.

Both my old '99 and '02 shoock a little when stock. New plugs and wires didn't help my '99 at all and I still run the stock wires with my '02.

Now with a TR230, I don't have to worry about my drink in the cup holder becoming unstirred.

yea, you aint kidding. i think i know how a can of paint in a paint shaker at home depot feels now. everyone looks at me like, wtf is in that car. it makes geting chicks attention alot easier.
i cant put more than a half of glass of drink in the cup holder.

Yes, with the cam, my shifter moves 1/2" - 3/4" from side to side at idle

My ls1 shakes too, but only visibly. You shouldn't sit in the drivers seat and feel it. I think you are ok.

yea, back to being serious here, alot of ls1's have a lil shake to them. dont sweat it if it still does it after new plugs and wires.

VietRacingGuy

thanks for the info yall.

i bought the car brand new from Land Mark Chevy in the end of 2002. after the first 1000 miles, i drive it like a ****, street race, drag race....with stock LS1
but i take care of my z28 real good, change oil at every 2500 miles, trans oil at 15K miles, alignment.....

the engine shake is not something i really worry about, but the ticking sound it make at idle that i am worry. i will try to get NGK plugs and some wires to see if it help.

under drive pulley and long tubes on the way!!!!!

My whole damn car shakes, thanks to the cam, but I like it

Although I don't think the spark plugs will cure any ticking noises, be sure not to get some that are too cold for your engine. IE, don't get TR6s!

The only thing to prevent shaking is to get it blueprinted and mapped I believe.
