UPDATE on Blown Motor

(Click here to view the original thread with full colors/images)

Posted by: camthman

Well, Finally got to doing some diagnosing on the LS. Seems like it wasn't a bearing like I had thought. Sound is coming from the top end. Most likely just a blown piston. Car blows smoke out the Valve cover breather, the car doesn't miss, and no smoke out the exhaust. Im guessing the skirt on the piston is cracked. Im still not sure exactly what Im going to do with the car. I have quite a few options that I have to look into.

Just thought I would let you guys know what the deal is.

...oh, and PLEASE someone buy my Bassani exhaust. Im tired of bumping that damn thread.

Noise, but no smoke, and somehow it's still firing on all 8?

If you were to hear the noise, you would definitely be agreeing with me.

I just want to know how the hell its still running on all 8.

Hey at least you didn't do this...

See that hole? There was another one just like it on the opposite side.

he had recently put a turbo setup on his LS but i can't recall if that was the cause of it or if it was the internals, i believe it was the latter though

Forced induction itself is not the problem with engines blowing. The problem either arises from the engine itself, the tune, or pushing too much boost for the engine to be able to handle. In Cam's case he has already mentioned that he suspects it was the engine itself being tired. He may find more out when the engine it fully broken down.

Sort of off topic, but this is what happens to a PowerStroke turbodiesel when you hit it with 103(!) PSI of boost:

At least you shouldn't feel quite so bad about your engine going...
