The more you mod the better the chance of KR. Run a high performance motor on low octane gas and you'll risk knock. Doesn't matter if it'* a 3800 or a 350 Chevy. Hi pro motors need 91+ octane.

As for the 3800 is a 3800 I don't know if I agree. The S2 in a SE or SLE has a different designation (L36) than a S2 in an SSEi (L67). GM doesn't change motor codes lightly. They may share they same displacement but the block itself could be different. Even if it'* only slight...

Any RG'* wanna weigh in on this?

Blocks are the same, as are the crankshaft and camshaft. Differences are in the pistons and rods, and in the case of the S2, the heads. Those are the biggest differences. Check out Curt Martins S2 buildup. He pretty much touches on all the differences throughout his rebuild.

I contacted the guy I purchased the car from. Turns out that he replaced the lower intake gasket just before selling the car to me. This work was done by a GM dealer.

Looking again..

I was aiming toward a chipped piston with the fuel questioning. Why... I'm unsure with a dealership diagnosis of bad bearings. To further that.. the low oil pressure merely agrees with their diagnosis.

At this point..let'* not clog up Tim'* thread with any more talk about 3800'* being a 3800.. that'* a good one for another topic and I'd enjoy that topic.

Now finding out that LIM'* were recently done.. there'* something to go on. There is a reason the gaskets were changed..and it'* not preventative maintenance. Go after the dealer that did the gaskets for misdiagnosis and the place that sold the car for some assistance with the problem.

That'* the key right there. On my original motor, coolant had gotten into the oil, but the car still ran for another 2 weeks after the LIM replacement. Then after 2 weeks, blown bearings. So, hopefully you can get some help in replacing that motor.

You guys on this forum completely ROCK! It is truly awesome that a geek from Jersey can get such incredible support and tremendous wisdom from guys who have "been there, done that"

I have a sinking feeling that I am in exactly the same boat that Matt was in. I spoke with GM customer support tonight and they are going to contact the dealer that replaced the LIM. Hopefully I will be able to convince GM that it was misdiagnosed and they'll help me out on the engine replacement. However if the dealer warned that this would happen, then I'm going to be out of luck... unless I go after the previous owner.

Well after one week I finally heard back from GM. They aren't willing to help me out with the cost of replacing my engine. #$%^&*(&^%$ I'm really not feeling the love from GM right now.

I have a couple questions for the group: If the LIM failure caused the engine damage is it possible that my supercharger was also damaged?

Does anyone know what is included with the new remanufactured engine? Does it include the supercharger? Cylinder heads?

When I had the reman engine done in my S10 I think it was a long block. This would mean you'd get the block with all internal components and heads. Intake and accessories get used from the old motor.

It will depend on what is purchased/how it comes.

Usually this is upfront. A long block includes the heads and typically oil pan, intake manifold and supercharger, accessory brackets are all swapped over.

And no.. it'* almost 100% that your supercharger suffered no ill effects. Being belt driven, the belt would have broken or something..

Thanks Karl & Bill. I stopped by the dealership tonight... and the old engine is out already... the tech was working on getting it off the cradle. I'm hoping that by Wednesday of next week she'll be purring like a kitten.

Do you guys know of any NY-NJ-CT events coming up?
