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. Attached thumbnail(s) ![]() |

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

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. |

(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. |
