I've had a couple of oil leaks on my fresh 2270, the most annoying of which seemed to come from the area of the oil pump and gradually got worse. Oil would drip on the underside of the engine mount cross bar in the center and air flow would then scatter it around (on engine, gearbox, exhaust, etc.). I bit the bullet this weekend and pulled the engine.
I then pulled off just the oil pump cover. I gather it's best to leave the pump housing itself in place if that's not the issue. I've got pics below showing where the lower oil pump gear has really ground against the cover, and a closeup of the gear itself showing wear on the gear. That edge on the inside lip of the gear is actually sharp to the touch. I would be guessing that metal on metal contact is not awesome right in the heart of the lubrication system, but I have also heard that those pumps do press against the cover. Not sure if this is the cause of, or contributor to, my oil leak, but how does this look to the braintrust? Assuming this is considered "acceptable," any tips for sealing this bad boy up so it doesn't leak? I've seen McMark's video.... Here's a shot of the pump with the cover on. Oil can be seen collecting at the bottom on the lip. If I had to guess it looks like it actually came out around the studs, as the nuts were pretty oily on the inside.  Cover showing wear...  Oil pump gears....  Closeup of the bottom gear. It's actually worn a sharp lip on that lower gear.  |

Did you go with the Modified Pump from EMW (Jorge)? Fixing the OD pump problem?

QUOTE(rfinegan @ Aug 8 2021, 06:19 PM)  Did you go with the Modified Pump from EMW (Jorge)? Fixing the OD pump problem? Hey Robert - no this is the modified 30mm type 1 from LN engineering (Type 4 store). I've used one before and it seemed to work well in terms of fit and function. I thought the fitment issue may have been more on the 26mm pumps, but I could be wrong. I actually thought about going to 26mm based on the oil pump size debate wars, but I couldn't find a good source for one already modified for type 4. |
