besides balancing and blueprinting what else is involved is getting my engine to rev higher…
My clutch has a whining noise
My clutch has a whining noise when not engaged but as soon as I depress the clutch it spools down. Once the clutch is released it spools back up to a whine. Took car to dealership and they said the roller bearings are out and the synchronizers are bad. My question is if my car is sitting in neutral should my clutch be whining even if the synchronizers are bad? As for the roller bearings, wouldn’t it only make noise if the car was in motion or moving?
The whining noise is coming from the release bearing(throw out bearing). The release bearing is built as part of the Clutch Slave Cylinder. The syncros may be bad but the noise has nothing to do with it. Bad syncros would just make it difficult to go in gear and possibly pop out of gear.
Worn or damaged release bearing
- Rotate the release bearing while applying pressure. If the bearing rotation is rough, install a new clutch slave cylinder.
Clutch Release Bearing
The clutch system is disengaged when the clutch pedal is pressed and engaged when the clutch pedal is released. When the clutch pedal is pressed, it pushes the clutch master cylinder push rod and piston, which transmits hydraulic pressure to the clutch slave cylinder. The slave cylinder compresses the clutch pressure plate diaphragm spring through the release bearing, releasing the pressure on the clutch disc. This displacement removes the spring load from the clutch pressure plate and eliminates the coupling friction between the engine and the transmission.
