Help me find my oil leak! Options

[bkrantz]

As I described in my build thread, last year, once I got the engine running, I noticed significant oil drops (or more) after each drive. With winter in full throttle, I decided to drop the motor, and see about fixing the leak.

Here's the view of the front. Maybe you can see some oil.

you have an aftermarket oil pump, they are very very very hard to seal

We have the same concern with an oil leak in this area, also running an aftermarket pump. Thanks to the good doctor. Why are they so hard to seal? covers not flat/

T1 pumps OD is usually a few thousandths smaller than the T4 OD. This allows some bleed by between the pump OD and the case. That puts all the sealing duty on that thin paper gasket.

I have wondered the same. Is this an application for a gasket in a tube? very sparingly of course.

Is there a doctor in the house?

No. It’s an application to use the proper T4 oil pump (with a pinned or peened idler shaft). (IMG:style_emoticons/default/happy11.gif)

T4 pump OD is 2.7565” using a smaller OD T1 pump and gasket in a tube is just a cobble job in my opinion.

I used a Schadek 26mm pump on a recent build and I suspect an oil leak at the cover. Not sure what is the OD of these pumps.

Bob, It makes some sense to replace the oil seal and O ring, but this is a difficult/tricky diagnosis.
