oil leak
Hi folks, I have a 59ab rebuilt engine that has a pretty severe oil leak, I'm not sure were its coming from, seems to be concentrated on drivers side soaking the wishbone and brake/clutch pedal area on that side wile driving, I cant seem to pin point it when on the lift with engine at idle. The pan is a 1934 and I see some seepage at gasket on that same side. I have a new gasket ordered but im wondering if anyone has had a similar issue. I cant recall if there is a seam between the pan and flywheel cover area or if its two separate pieces piggy backed. Thanks for any help. Ken

Re: oil leak
There is an additive to put in your oil that carries a dye that shows up with an ultra violet light. It works like a champ to find leaks. It comes in a kit with additive and the light.

Re: oil leak
Sounds like it is around the vent hole. Some gaskets don't
work around that hole. G.M.

Re: oil leak
34 pan has no vent.
the pan gaskets are different on an early pan with no vent to a later one with the vent, they are different in the area that the cork main cap gasket goes onto the pan gasket. Lawrie |

Re: oil leak
so on the lift you cannot see a big leak but driving the car results in a big noticeable leak? if this is the case the oil is climbing the back of the pan and going out around the gasket
