Cracked # 4 piston
First off welcome to the club.
secondly, I'd reccomend diamond racing, you can probably stick with the stock rods unless you are going for crazy hp. Rod bearings and save your pennies to replace all the bolts and get a cosmetic headgasket and arp headstuds, along with The random little stuff and you are good to go. Your probably looking at 1200 bucks..... Arround that, when it's all said and done
I just read the whole thread, if I were you I would do a little investigating before you buy pistons, definately run a compression test, are you getting blowby?

Thanks for the advice? Sorry whats blow by?
I hate you sig.... AHHH ROLLED

It's where the compression rings in the piston have greater clearance to the cylinder wall and oil gets past the rings and burnt in the combustion chamber.
The car will blow dark smoke out of the exhaust (burning oil).
Because the clearance between the piston rings and the cylinder walls are greater, fuel can also be forced past the rings into the engines oil, which dilutes it and can cause premature wear to the bearings because the oils sheering/cooling properties has now changed.

Well the stealership quoted me for 1900 dollars just in labor to replace a single piston. This is honestly not something I can do. So I am going to do some research but I need some ideas on what I can do. Looks like something I am going to have to do myself. They are saying they need to take the block out, which I know is not required.
What tools am I going to need to do this, I have a couple how to guys. But I guess I am going into this ***** deep. I have a general knowledge of the car.
FYI, anyone that wants to help me install this I would be willing to throw a pioneer in dash/dvd/nav/bluetooth set your way. I would even install it if local. Really need some help here. This is my DD.

ahhh #4... lol when it happend to me i just did the work myself.. took a little less then a full weekend and 2 12 packs with a friend.. i personally think the lsj engine is easy as hell to work on.. i didn't run into any huge problems. I would get the eagle rods and diamond pistons. I have a few friends with that set up and tehy can't complain and love the added security. grab a set of ARP head studs cometic head gasket and your good to go and a new cat... or just take it off completely haha

Clearly I did search, I checked the FS thread and nothing recent for sale. I did a google search on cobalt 2.0 headers and nothing of help came up plus I had several other questions. Get a life dude seriously.
Anybody have an idea on what I am looking at to have a single piston installed?

I ordered the GM book for the LSJ from crate engine depot. So hopefully that will help. What special tools are needed for the job. Are they expensive etc?

Piston ring compressor
torque wrench in/lb and ft/lb
Cylinder wall hone depending on how the walls look
I personally don't see you needing rods. The pistons are the weak point of the lsj. Rods themselves are pretty strong
I have spare stock pistons laying around if you are looking to just throw some in

Good luck getting your car running though jcutler.
Thanks man!!! I used to be in your neck of the woods. I lived in NoVA before I came down here.
And I agree, some of the kids on these forums are just trolls who care about a post count.

Are they sold?
I am guessing they were sold before this thread was even created. I have been in and out of the for sale section for the past week and never saw a set of pistons being sold. Anyways, your post is not contributing to this thread. Just trolling. Move on
