pull the pass valve cover look for bent push rod. if you find nothing broken then its a rod or piston. plus it sounds like you got skrewed on the deal. Sorry to see it happen.

 

I'm planning on pulling the valve cover here in the next few days. Maybe I'm still ok on the deal !

 

when you get the cover off there should be no play in any of the rocker arms if you find some in one cyclinder then that is the one you remove the rockers from and check for bend push rods or maybe a bad lifter. Good luck and keep us posted.

 

Thanks, and I will keep posted.

 

What have you found???

 

Gonna try to pull valve covers this afternoon.

 

Pulled the vavle cover, no issues with rockers or pushrods. The sounds really seems to be under the intake now. You can feel it on the intake bolts, cant feel anything on the valve covers or heads. My luck its a rod or something in the bottom end.

 

Ugh. That does sound like the rotating assembly.

 

I was afraid of that.

 

LS1 engine noises are hard to diagnose without really digging into it. It sounds like a lifter to me but could honestly be anything. Try making a video with it hot and rev it to about 3500 from a idle. If its a rod bearing it will get louder as you rev it. If its a lifter cam related it will stay the same.

 

When the engine revs the sound speeds up and when you let off it kinda pauses for a bit or atleast thats the way it sounds.

 

Pull the heads and look at the lifters. Then pull the short block if needed.

 

Yeah I really dont want to get into all that, gonna try to sell it like she sits. I have found a truck I want to buy so the car has got to go. Price reduced $10K.

 

good luck selling that for 10k... in this economy I don't see that happening with a busted engine. I doubt I could sell my modded car that runs great for 10k right now

 

Thanks ! I think it will bring close to it.

 

let us know... if so, then I know what kinda ballpark I'll be putting mine in LOL

 

Ok, will do.

 

I don't mean to rain on your parade, but I paid 12,500 for my Z28 with only 11k mi, this last july. 10k is pretty steep for a car with a hurt motor imo... If you fixed it, then yea it's worth 10k +. Good luck

 

dam i better check mine like that couse i have a funny sound at 2500 rpm and im thinking a rod also.but mine at cold nocks and warm it does it at 25 and up but not louder just stays the same and dont go away.
