Re: 86CGT oil pump problems?

["Fred Munro" <munrof@isys.ca>]

Jeff;

    You have to remove the securing bolts from the top of the oil pump
housing to do the t-belt job, so the fact it is leaking there is suggestive.
You may have left out one of the oil pump retaining bolts. These are 10 mm
bolts, but I think they are longer than 1/2". If you didn't torque these
bolts properly, you may have a leak at the gasket under the loose bolt.
    Pulling the oil pump may be a PITA - I think you have to drop the oil
pan on the MC motor - not sure about the Coupe motor.

Good luck!
