I've been hunting down an oil leak with not too much success so far.

First the rear head cover gasket leaked oil in the near of the TB, down on the rear 97+ header. That has been fixed successfully more than a year ago. Now, it takes some months to build a drop of oil on the gearbox side, the stiffener between the gearbox and the engine. It also drops on the front header end letting it smoke when hot.

It's not the VTEC solenoid. I thought about the head gasket.

Is it possible for the lower 97+ header shield to store some oil in some pockets and release it while driving?
