I think my motor is screwed
i went on the hwy to try my nitrous
sprayed @ like 80 km/hr, check engine light came on so i shut her down turned of the nitrous and i was pulling of the hwy and i hear a knocking sound!
i took off the valve covers everythign looked fine
it started while i was slowing down
sounds like its coming from the drivers side cant tell from what!
Spark plugs are good
oil pressure is good
dunnno what to do!!
time to take it apart tomorow

hmmm well lets start with some basics...
is the car STILL making these knock sounds? does the sounds get louder as you rev the engine? how does the car run? does it seem like it runs slower now?
let's check and make sure you didn't bend any pushrods or anything.. take the valve covers off and see if any of the roller rockers seem loose etc..
i'm not trying to bring up bad news YET so let's check these thing's first

when i rev the motor the sound SEEMS to stay the same
the car runs fine just gets lots of knocking
i havent had a chance to check the passenger side valve covers cuz of the alternator being in the way.
ALSO
also someone told me to check my y-pipe since this happend when i was de-celerating
i also have a stock timing chain as well if that means anything?

check to make sure it's not an exhaust leak also... are you running headers?
it's really hard to say without knowing what kinda knock it is or where it's coming from :blah:

and you say the knock DOES or DOESN'T get louder as you rev the engine?
may need to tighten those header gaskets up as well...

well you could be in good shape then... you say the car run's fine other than the knock, and the knock definately doesn't get louder with engine speed, and the oil pressure is fine... so i would just start out by checking your exhaust for leaks (y-pipe, headers) tighten all those header bolts when the car cools down...

Change your oil, and chisle open the filter. It sounds to me like you spun some bearings, if so the oil will probably have little slivers of metal in it, it will look like glitter. I really hope its not rod bearings, but you are going to have to check sooner or later. Post back with what the oil tells you and if you come up with anything eles.
