I recently looked at a 2002 LS1 Camaro to possibly buy. It has 57K on the clock. When I started the car up and let it idle I could hear a ever so slight knock. The car had mint oil pressure and seamed to run great. I checked out some of the LS1 message boards and no real information. They say piston slap. It's not uncommon and people just deal with it.

What do you think it could be?

They are right, just call it "Slappy" Laughing They pretty much all do it (at least what I've seen). Common with the newer GM stuff. I had a friend get a new engine from GM in his 2002 3/4 ton pickup before it even hit 10K miles. They say its not harmful, but imagine how much $$$ theyd have to eat if they actually put out a recall on them!
I say as long as its not obnoxious, has good oil pressure, and goes away quickly youd be in good shape.

ohh no, are we gonna lose you to the 4th gen crowd? Pretty soon youll be bragging about how you ran a low 12 (with $2.00 worth of bolt on's) with the A/C on while getting 20MPG!
Nothing wrong with them, actually I think its by far the best motor GM has ever made, but I dont like the wrapper Confused

2x4 it's better than losing me to the import crowd... aka WRX or SRT-4.

I'm not the bragging type. Just lazy. I thought about swapping an LS1 into my car. But for not much more money I can have the whole car.

Very Happy They really are great cars though, best thing made since the Grand Nationals & Impala SS's. If I had the space/cash I'd have one too! Did have a 93Z, but the LS1 is far better than the LT1.

I have heard that the knock is actually caused by carbon buildup, either way it is not fatal.

2x4, I like the Impalas too, but I am cheap so I have the Caprice, same LT1 heck same car(Impala is strictly a trim option on a Caprice). The 93 F-body was a speed density LT1. Your feelings about that motor might be different had you had a 94-5, the MAF system is much more adaptable and tuning software can be had cheap. Not to mention mods are cheaper, my cam was under $200, try that with a LS1.

As stated before Piston slap is pretty common with the LS1 Mine has done it since New. It usually goes away by the time the engine reaches operating temp.
As for a cammed LT1, My buddy has a 6spd 94 Z with LT4 Hotcam, shorty headers, SLP catback, CAI, tuning and 4.10's. And he is just keeping up with my stock LS1 with 2 bolt on's. Cool

9Y8W66... No doubt the LS1 is a great engine. I would love to get one. I think I'll go back and have a look at the car again. Maybe offer some cheap money for the car. What does your car run?

Does your car have the oil consumption problem that other LS1's experience? Is it true they fixed the problem in the 01 - 02 models? The other rumor is most if not all of the 02's have the LS6 block?

Smokemup
I'm at 83k miles and have just started to notice some Oil consumption. But not enough to worry about. Don't know if the later cars have less of a problem. About 25% of `01-`02's have the LS6 block.
Mine has been my Daily Driver for 5 years Winters and all. Never had an Engine or driveline problem. Still has the original clutch. Car has ran a best of 13.57 @ 106 with mods in sig. 60ft time is a only 2.28, I havent wanted to abuse the stock clutch on the launches, because the car is my daily driver. Cool

I'm going to go look at the car again this weekend. I'm planning on offering short money and see what happens. I know the dealer has been sitting on the car for a while and maybe ready to make a deal.

The car is a 2002 hardtop A4. It has no options, which is what I want. I think the only options are leather interior and A/C. It has manual windows, manual locks etc.

If I get the car it will be my daily driver, snow and all. I plan on putting a converter, headers, cat back, cam, UD pulley, lid, & bellows. From what I've read that should be a solid 12 sec car.

I thinking about heads but I want to wait and see how the new AFR's compare to the ported GM heads.

Probably going to sell it. When that car goes a part of me will go with it. That car was the whole reason for this site.

I know how you feel I had a `78 Z that I loved, but lost it in a accident. Used the insurance money to buy a `79 T/A that I owned and modified for 7 years. I left alot of memories in that T/A. But times change, I needed something Fresh and New. Don't get me wrong I love 2nd gen F-bodies, I plan on getting another one again someday. But the LS1 is a far better car overall IMO.
