Having problems with your GMC Jimmy ?
I hav a 98 gmc jimmy rwd 4.3 vortex vin# w it knocks all the time gets louder as u accelerat sound like it in the middle of the engine
I would not drive the vehicle until i had the engine repaired, sounds like you have a connecting rod bearing that is bad or more than 1, the motor will need major repair or replacement it will all depend on how bad the damage is to the crankshaft or any other components. sorry for the bad news but i hope this helps you
