Ok I haven't had time or a chance or place to look at my engine. I figure I'd ask the guys here who seem to know a little bit more about stuff than I do and try to figure out what went wrong. Ok so Friday morning I went to start my car up to go for some errands. As soon as it started the engine was shaking and knocking violently. As soon as I could I shut it off. I thought maybe a cat or something crawled in for the night as it has happened to people I know before.
So I popped the hood nothing there, did a visual check and everything looked alright. So I figure I will start it with the hood popped and try to sneak a peak at it while the hood is up. Start it again. As soon as step out my car is just pouring oil out from underneath it. So I shut it off immediately. Went to look under the car and I was able to scoop out a few pieces of metal each about the size of a nickel. I am going to get it looked at sometime this week hopefully. But what do you guys think it is with the limited bit of info I just gave? Car just hit over 100k but supposedly the engine was replaced around 50k with a ls6 block. There were no signs previously that something was up. I took it out earlier last week and nothing everything felt, sounded, looked fine. I just don't know.
Thanks Brent

 

Threw a rod and trashed the motor.

If you have a brother I would go kick his ***. If it was not like that when you parked the car...

 

Thanks thats what I have been thinking and what others have suggested. No brother and no one else drives the car. The last time I took it out it was fine no problems whatsoever. I typically don't drive it like I stole to so me abusing it ain't a problem. I drove maybe 15 miles altogether the last time I drove it. I don't know its wierd that it just happened out of the blue. Thanks again.

 

Sounds like you threw a rod and took out the block in the process. Did you see were the oil was coming from?

You can just jack the car up and follow the trail. Good look on the rebuild. A cheap solution would be just to replace the short block with a used one. They're pretty cheap now days. I've seen them go as low as $800-$1200.

 

Yeah I'm going to take it to a friends house and we will see the damage. I live in the barracks and don't really have space for jack and stands. Will defintely have it up this weekend hopefully. Ill post some pictures of the damage when we get it up. Right now I got an ad up on the WTB section. I just gotta shop around. Being in Hawaii sucks *** on shipping. There are some good deals in there its just shipping sucks.

 

Get your injectors checked before you put them on another motor.

 

I have seen cars hydrolock from sitting in bad storms and hitting moderately small puddles (Gotta love the intake design on an LS1). The symptoms are identical to what happened to you. I couldn't tell you if it was water based, but you for sure shot a rod or piston (if you dropped a valve) out of the motor. A lot will need fixing if you plan to keep that motor.

 

Im just going to get rid of it so no worries there. It has been raining like crazy here lately but I didn't hit no puddles or anything. I'll check the injectors too before they go in another engine. Thanks for the info.

 

Also if I go with the LQ9 route, what if any at all problems might I run into going from an LS1 to that? My understanding it should pretty much be take the ls1 out and put the lq9 in? Is there any little problems or what not when making the switch?

 

Bet the intake bolts are loose and rain water leaked past the crapo windshield cowling into the engine. GM uses a high torque starter so instead of hydro locking and stopping the starter BREAKS the engine into pieces! THANKS GM.
