Rover 216 has developed a vibration at 2400-2600 rpm.
It's bad enough to be felt through the whole car and makes the exhaust rattle at the rear !

Only thing I can find is some noise from the cambelt tensioner when using the Long Reach Pozidrive Stethoscope.

Has anyone experienced this bearing causing severe vibes or should I be looking
elsewhere ?

we had the same on our 216 si and it was the engine mount on the cam belt side.

Do you mean a 200 1.6 ? rather than a 216 ?

One known source of vibration on these engines is the crank pulley & sprocket can work loose after a cam belt change. The alternator pulley has also been known to work loose and cause vibrations but only on car with the older style Lucas-Magnetti marelli alternator.

Fault crank sensor connections can also cause random misfire related vibrations at around the crank speed.

Also do the usual MEMS checks, Depending the version of MEMS fitted the MAP sensor can either be be located in the ECU or on the inlet manifold, if the latte clean out the small bore connection pipe VERY carefully. Also clean the main earth point for the MEMS ECU, this located on the bonnet landing panel just above the left hand head lamp.

If it is accompanied by power loss renew the plugs and suspect he coil packs (if fitted).

I stand to be corrected, but a 200 1.6 is a 216 ???

I thought the 216 had the old leaky single ohc engine "Pants on wheels"
Steve.

216 were the older models first generation had the BL S series engine -- really a much revised Maxi unit, second generation were all Honda powered.

Third generation are just badged 200 which later changed to 25
