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) ![]() |

The fan tends to suck in and redistribute oil all over that side of the motor. Most of my experience is with type 4 powered buses where the fan is at the back, but I think the power of the fan is more intense than any air flowing by. The most common leaks are pushrod tube seals. You wouldn't think that oil all dripping from the area of the bottom of the fan would be from there but my experience with ultra violet dye says that's where it comes from most of the time.
People will argue that viton seal will work dry, but that hasn't ever worked for me. The best thing I've found is a bit of ultra black silicone on them, but even with that, it's only a matter of a few months and it starts to leak again. |
