Thread: I think I'm in big trouble, knocking sound from engine....

169k miles. What really sucks is I took VERY good care of it and is otherwise in perfect condition (minus a few dings you know).

Literally everything works on it, tranny shifts perfectly and so on.

It happens dude. Don't stress over it, find a good JY motor and swap it in.

Damn have 264k gen v on a 3.3 and cant seem to pop a piston trying hard to have a reason to install new motor

This would be the second 3800 that took a dump on me, first was my bonneville which made it to 180k miles.

I'll probably sell the car and get the wife a new SUV. I'll drive her TL instead.

I'm over these 3800's.....

Damn that sucks

If it makes you feel any better I'm on my 3rd gp the most recent is on its 3rd engine.

Lol im on my 3rd transmission 1st one was forward band second was first gear burnt and now the 3rd is the stock one i rebuilt

CHECK YOUR BALANCER! Just like the previous posts, take off your belts reach in and see if the balancer moves. If it does that means the rubber is shot and you will have to replace it. My GTP sounded the same and well it was the balancer

Check balancer first, easier fix

Lol, what good would fixing a broken balancer do if the bottom end is shot?

a broken balancer can sound like a blown rod bearing is what they are saying, its free to look at it right?

Yeah but sparklies in the oil = engine is done anyway.

unless he was just seeing the sun shining on the stick? lol

i always try to root for a not blown motor.

I was at first too, Tyler and I both said to check the oil, and I agree with Tyler he should drain the pan, 5 quarts of oil and a filter is like $20 at walmart.

Wanna know the easy way to tell if it's a motor?

It sounded like it might be and then stopped starting nice. Balancer shouldn't cause that, flex shouldn't cause that.

90% sure from the vid, it's a motor. Definately though.. give it a quick rev ...the noise a lower end makes on decel is unmistakable

Just checked another video I had made, its makes a lower pitched "knock" on decel but it makes a higher pitched "knock" on accel. Pretty sure its toast, especially with finding some sparkles in the oil.

I will obviously check the balancer just for ****s and grins.

Thanks for the help guys

I haven't started since day one Vet........it was an old video.

And no, I haven't drained the oil. I've been too busy but I'll be sure to do that.

So any update on this?
