Compression check

Hi

Pretty sure it's a no but is it possible to do a compression check on a rev 2 engine on an engine stand? [/b]

Yes, if you hook up the starter motor to a battery with a coupe of hefty (jump) cables.

Yes of course it's possible..as long as the flywheel and gearbox attached to the engine.

Thanks

You do not need a gearbox attached.

How can you do a compression check then on 3s without a starter motor attached to the gearbox? I've been asking a local scrapyard to do the compression check make sure engine is ok...but they say they can't do that without the gearbox! Any advise will be very helpful. Thank you!

Sorry I was thinking of a more traditional starter arrangement where it's mounted parallel to the engine pointing towards the flywheel.

I forgot on the MR2 it's mounted from the gearbox side.

Gearbox or at least the bell housing is essential as that holds the starter motor.
Unless you weld together some makeshift bracket for the starter.

You would want to rotate the engine at a constant rate at few hundred rpm as the starter motor do to compare it to expected values written down in the service manual.
