Rover v8 Bad Vibrations.

dejer, Oct 12, 8:45pm
Nasty fine vibration in my Rover sd1 v8 very hard to diagnose. Drive chain is all good, vibration is constant, even when standing still. Worse at some revs than others - can be felt through steering wheel and gear lever. Engine runs sweet. So, Could it be Flywheel out of balance! Vibration damper!, crank pulley!, alternator!, crankshaft!, bent con rod even! (injector hydraulicking can do that so I'm told) Where do I start looking! Any tips out there!

yup more like engine mount. you would hook a engine crane to the engine and start lifting it up and the vibration should be gone then if so you got a stuffed mount transfering the fibration from the engine in to the car-body.

Auto or manual!

If manual, have you recently done a clutch job!

I have had similar, the clutch pressure-plate was out of balance.

Good luck.

Have a vague memory that the Rover V8 can drop a main bearing cap number 4!.Can you get the sump off inan SD1! as if so not very hard to run a torque wrench over the bolts just for peace of mind.
