And thank-you for the entertainment. E-thugging is one of my specialties NGA!

WFT ....

back to the subject guys ...

and no it doesn match the revs, it does not get higher as the revs get higher , infact in
gear 3,4 and 5 the knocking noise is low .

have i spun a bearing ?

Re: ENGINE KNOCKING LOUDLY ?
 

Wait, run for titles? Where are you?

And yeah, you probably spun a bearing. Tear it down and find out. That or you have a weird exhaust leak bouncing sound off of something else under the car. That's what the Z24 had for a while

Wow! ???

Re: ENGINE KNOCKING LOUDLY ?
 

id say spun a bearing..been there done that...

off topic-- bensbaby, you are extremely annoying...please take your 2.5 brain cells elsewhere, your antics have given me a headache and a sudden thought of why some people should not reproduce..oh wait...you dont have to worry about that unless your hand can get pregnant...

Re: ENGINE KNOCKING LOUDLY ?
 

It could possibly be a spun bearing, but usually the noise increases in speed as engine rpm does.



Sorry, I know it's off topic but I just caught this...
So he has a 500hp motor and makes 460 at the wheels? 40 hp for drive train loss, I think not :P

Re: ENGINE KNOCKING LOUDLY ?
 

good point..i thought he said 450hp, 460hp and 500hp..wow..thats a really flexible build...ha..

Re: ENGINE KNOCKING LOUDLY ?
 

just free-rev it and see if the noise changes with rpm

Re: ENGINE KNOCKING LOUDLY ?
 

I can vouch for a rod bearing. I've thrown two. First when I ran the car out of oil(young and dumb), second when the welded crank(i'm a poor college student so eat ----) had another bearing spin.

Essentially, if it's a rod bearing it first sounds like a marble jumping around in your engine, typically wouldn't be able to hear it too bad at the top rpm's. Then as things progress it gets much worse and makes its way through the rpm's. No longer will engine noise shroud it. Then at the point it is very loud, u'll have 1-2 days left of driving. once its gotten terrible, huge hp drop and the car will essentially die. I had to have a Kia tow my ass up my hill when mine went the first time.

I wouldn't be suprised really to find out it was rod #1's bearing that went out. lol. prepare to spend a ---- load of money with a rebuild or prepare to do it the cheap way and not know for sure how long it will last.

Re: ENGINE KNOCKING LOUDLY ?
 

My folks have a 1990 prelude si with some pretty sweet rod knock, the sound definitely gets a louder as the motor goes under load but you cant hear it as easily over like 4k rpm. I think it sounds like a sewing machine... What were your rod bearing clearances like when you put the motor together?

Also I looked at Bensbabys mods list and am a little confused. Why does it say:

"Drivetrain Layout: Front Engine, Front Wheel Drive."

It explains the LSD.. I dont think AWD with slicks need an LSD but maybe I'm mistaken?
