98GTstang

Well a few months ago, my 98 GT started to make a knocking noise, only happens in gear and while driving..(cant hear it at idle). The higher the rpms, the faster the noise gets..the thing is when i parked it in the garage to let sit until i had time and money to fix it..the rear differential drained all over my floor. I havent drove it for about 3 months and now im wondering if the motor is actually blown, or if the drivetrain is making the noise..Is this possible? I havent had it checked out by any mechanics, cant afford it. But my dad is a mechanic and has been for like 20 years and said its probably from the motor, even tho he didnt really look at it..lol Can the drivetrain/transmission cause this noise?

tell your dad to take 10 minutes outta his busy life and help you...

you shouldnt have to wait 3 months for a response.. he can hear the noise so he could diagnose is much better than we can..

Well, its not that easy, hes a busy guy. Hes getting old and hes in the process of getting re-married..so i try to leave him alone as much as i can...just asking if a tranny or something can trick you into thinking your motor is blown lol...

Probably can. I mean maybe something went out of balance. Flywheel or throwout bearing. I dont know much but those are some things that i would have checked out too.

Hmm, my throwout bearing has been squeaking for about a year now

Sounds like it could be the timing chains going out.

Is it a tick or a knock?Theres a big difference in the two once you have heard both.

If you rev the car in neutral does it make the sound? If it only does it while its in gear I would think its something other than the engine, if it were the engine it would make noise no matter what.

if it was knocking youll know it and it wont run for too long, sounds like a tranny or valvetrain prob.
