I was on the freeway trying to catch up with traffic and as I was ready to shift into 5th i accidently shifted into 3rd and red lined to the max. Now I had a horrible knocking noise and the car sounds like a lawn mower when accelerating. What could this be, the car drives around fine except for that knock

 

you messed up your whole engine, no pass the turbo kit down to me lol

 

Sounds to me like your car has come down with a case of the Civic Flu.....its been going around..


but seriously, i wish i could help

 

do you think i bent some push rods?

 

time for a compression test and leak down.

 

Maybe your car is trying to joke with you...

You know.. Like..

Knock knock...

Next time you drive, just ask... who's there?
It will stop... Or finish with the joke and send a piston out the hood. Lol

 

 

HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA HAHAHAHAHAHAHAHAHAHAHA


No.

You could bent some valves, and fucked all your pistons up.

Along with blown your diff on your trans up.

How fast were you going?

 

I had the same horrible knock when I was racing a mustang I took off badly and I heard a knock but it went oway when the car cooled off so I really don't know what it could be since mine went oeay lol

 

well Alex, it could be a few things, but in short they all pretty much involve an engine rebuild.

could be a wrist pin, connecting rod, ...i dunno too much about the particulars of the internals of an ecotec, but maybe the balance shafts...no matter what it is, it'll cost you some money

 

Our DOHC cars don't have pushrods..........

 

^^^exactly, however a nice v8 would

 

if you hear knocking answer the door

but seriously how fast were you going?

 

LOL i know i just remembered that.

I took a stick and I placed it around the engine trying to find the main area of the sound and put it against my ear and most of the noise is coming from the intake mani on the furthest right....facing the engine

 

lolz

 

Soooo... how fast were you going... because you would have had to have been going faster than like 120mph to really damage anything.

Oh wait... you have an LS... nevermind. You still would have had to have going very much above the speed limit.

 

intake valvue?

 

ive deffinetly loosened something, i dont know i was starting to get on the freeway reving high on 4th then i slipped up

 

Honestly... are you ******* serious? Who does that? Tonto?

If the sound is coming from the block... then it is very possible that you have a bent rod, although I don't think over revving would do that.. You should stop running the car ASAP. You are only further destroying your engine.

 

is there any cel.

 

that is ******* amazing!

 

120 in 4th is like....almost redline on a 2.4SS which is same trans different final.

HAKLPASNDALSDHOGHDSG!

SDOIFYA8S9H!

 

intrestingly no cel

 

******* Tonto

There aren't sensors built into your rods that pop up a CEL when they are bent.

A CEL doesn't come on when you bend a valve.

YOU ARE GOING TO HAVE TO BREAK OUT YOUR MAGICAL HEARING STICK AND TEAR THE ENGINE APART! PLAIN AND SIMPLE!

I'm glad you liked that.
