Here is the problem.. my GFs 1999 GSX with 80k miles has a knocking sound.. when you drive the car under 3k in RPMs you dont hear anything.... it drives fine, up until you hit 3k+ you'll hear a loud knock, sometimes the knock wont be there but most of the time it is.... if you slam the clutch it stops. My friend said it could be bad gas, someone else said it was about to blow the motor. but shouldnt the knock always be there if it was the motor about to blow? I dont know much about the 4g63 motor so im tuning to you guys as i dont wanna take it to a shop and get rippped off. anyone who can help me out? please contact me on AIM my name is eclpsed on there thanks much!!

PS if you want to hear it in person the car is in VA beach, VA. thanks!

its yer dang turbo knockin cuz!

 

i wish it would be something that easy.. cause it's only about 10k on that turbo. SBR would be getting me something new :P

 

If I get some time I'll take a look at it for you.

 

throw out bearing or *cough* thrust bearing

 

Crankwalk, duh

 

shouldnt crank walk knock always? and not jus randomly? i was doing 45 in 4th gear a few mins ago (on the way home form getting some gas) and no knock at all...
