Thread: Engine out...was hoping it was a cracked flex plate but it wasn't

Like the title says I finally got around to pulling the engine out of my GT. Was hoping that the knocking sound was just a cracked flex plate. But that wasn't the case. This is what I found in the oil pan

Looks like I'm on the hunt for a replacement engine.

I bought the car with the knock issue already so I don't know what conditions were when this happened. I didn't see any coolant in the oil when I drained it or in the pan. Anyone have any theories on what might have happened?

Nice job...seriously.. that's tought to do.

!!! that is wicked! i never seen a cap busted like that haha. im currently purchasing a motor myself. mine had seized. i would suggest buying a good used motor. im picking mine on car-part.com. 55k for 1400. ive already considering buying a remanufactured motor but imo for the price, you cant beat a good used motor.

WOW! Dont fret, thats why they put 6 of those in your engine. For backup, in case you break one or two.

but seriously... it may have just been a bad a/f ratio that was causing knock which was putting strain on the internals. which may have just been a vaccum leak. or maybe your cat was clogged. it could be a multitude of things.

my guess is it got a rod knock, then some one just floored it till it blew.



i had a friend who had 78 t/a, had a 400 in it cam heads, intake and Nitrous. it got a rod knock, so he put the brick on the gas pedal, then reached in with a broom stick and hit the red button, it screamed bloody murder and grenaded. he took it all apart all the rods were bent, push rods looked like pretzels, and the cam broke into 3 pieces. heads took a beating as well, there went 4 grand real fast.

Omg Scott.... Haha

Wow that poor 38000.

Have you checked out motors from LKQ or Morads? They're prices are reasonable. Or see if anyone on here has a spare they'd sell.

I bought this cheap due to the knock and was hoping for a quick cheap fix. Really have to idea what happened but it was owned by a college student. His dad said that he had no idea what happened just started knocking. He went and got another GP and switched some parts with this one. Now I'm thinking there is more to the story. As I was pulling the engine out I was amazed at how easy a lot of the bolts and other things came out. Then I found a bolt missing from the transmission and a missing piece from the flywheel cover. I'm sure this engine isn't original to the car.

Check out Dahmer Powertrain. They quoted me $1200 (plus core charge) for a reman 3800 with a 3 year unlimited mileage parts/labor warranty. That included delivery since I am local so not sure how much shipping would be to you. I found a 26K engine out of a 2006 for $475 so I will probably go that route.

If you're willing to take a lil drive..... 3800 series 2 and transmission his last 4 are 4242

Also, dont let him pull your leg and try to tell you he wont split them. He told me $300 for both or $200 each.
