    Merc DIstributor Cap ?-gctid405965

    I just did tune ups on both engines.

    My question is why do the caps have the 90 degree vent which looks more like a drain?

    Does any one have a quess ?

    I am thinking it's there to allow heat and pressure to escape. This might be because the cap has a gasket seal between the cap and distributor base.
