ROLEXrifleman Posted November 10, 2013 Report Share Posted November 10, 2013 Anyone familiar with this series engine very well? I'm looking at one where the car drives fine but is making a noise under throttle that as the RPM's increase so does the whine. I almost sounds like an old belt that needs to be replaced but it's not. As you give it throttle the noise gets higher pitched in sound and appears to be coming from where the aly is but my hearing is so bad I cant tell. Any input? I've heard the 3.8L is almost indestructible. Rolex you sicken me. Just let me finish my pie ~ Juice Link to comment Share on other sites More sharing options...
ROLEXrifleman Posted November 10, 2013 Author Report Share Posted November 10, 2013 could it be the belt? otherwise what can it be? Pulley or idler arm? how would I check? Rolex you sicken me. Just let me finish my pie ~ Juice Link to comment Share on other sites More sharing options...
BASShead12 Posted November 10, 2013 Report Share Posted November 10, 2013 Is it supercharged? Take off the accessory belts and check all the pulleys: idler, tensioner, power steering, alternator, spin them to see if they make scraping noises or check for wobble. If it makes the noise only when your ac is on it could be your ac condenser.

ROLEXrifleman Posted November 10, 2013 Author Report Share Posted November 10, 2013 not SC. Turned ac off and still there. This is on a car i'm looking to buy, just want to make sure its nothing crazy. If its a belt or puller or arm no biggie, I can fix. but I don't want to go into a motor! This is the 1st 3.8L I've ever considered buying. thanks Rolex you sicken me. Just let me finish my pie ~ Juice Link to comment Share on other sites More sharing options...
BASShead12 Posted November 10, 2013 Report Share Posted November 10, 2013 if its not knocking and just whine it should be an easy fix Hu: Alpine CDE-141 Eq: Clarion EQS-746 Mids/Highs: Alpine SPR-50c 5.25" components Mids rear: Alpine SPR-69 6x9 Mids amp: Alpine MRX-F65 Power/Ground: Massive Audio 4 AWG Signal Cable: Massive Audio 14 Gauge RCA's: Monster cable Subs: 2 Rockford Fosgate HX2 12's Sub amp: Crescendo BC2000D Custom box - Herculiner with Silver port Big 3 and power/ground - Sky High Car Audio 1/0 OFC Coming soon: H.O Alternator Singer or Mechman Link to comment Share on other sites More sharing options...
rickybobby Posted November 10, 2013 Report Share Posted November 10, 2013 try reving the motor by hand at the throttle body and carefully use along screwdriver, one end on the accessory, alt, p/s pump,... and the handle end ON your ear. you will here the same sound through the screwdriver. 03 s-10 owned since 35k now 150k alpine type-s 6.5 comp alpine type-e 10 ported fiberglass jl 300/4 (dead) jl500/1 (dead) Link to comment Share on other sites More sharing options...
Guest Posted November 10, 2013 Report Share Posted November 10, 2013 mine whines a bit. non s/c. i've heard some 3800's that whine because of the power steering pump. but yeah the motors are crazy strong. as long as the intake manifold gaskets have been replaced or are in good shape and not leaking coolant. the transmissions (4t65 and such) on the other hand are a joke lol.
