1930 Model A diaper pan
My diaper pan collects quite a bit of oil, and if not careful, sloshes out and onto the road. What is the cause of abnormal amount of oil? Crankcase dipstick is 1/2 full today, and I have to remove and empty this pan much too often. If this a big repair?
Thank you! |

"What is the cause of abnormal amount of oil?"
Assuming you mean "oil leak?", it's usually either a sloppy rear main or missing gasket between the block and flywheel housing.

Re: 1930 Model A diaper pan
Thank you, Katy. It didn't use to leak this bad, so I'm thinking the gasket is there, but maybe worn out, or your suggestion the rear main. I hatge to think of pulling the whole engine.

Re: 1930 Model A diaper pan
Are you using synthetic oil? If you have a marginal issue synthetic oil will make is much worse. I use 15-40 diesel tractor oil.

Re: 1930 Model A diaper pan
Fitted the roadster with a roaddraft tube oil filler. Could that cause the adverse effect seen by the above posts?

Re: 1930 Model A diaper pan
Is this a high mileage engine?
What weight oil are you using? I have never owned a Model A that did not mark its spot. Just a couple of drips, not a puddle. On higher mileage engines. I have been using 20W-50 HD oil with one blue bottle of STP. This formula has worked well on oil dripping issues. Also engine noise. Thinner oil, increased oil dripping. Enjoy. |

Re: 1930 Model A diaper pan
Have someone step on the clutch while you watch the front pulley. You should only have less than .005” movement, and that’s stretching it. I’ve seen some with .020” ,which allows a pretty good rear main leak. You can also undo the three bolts that hold the inspection cover to the fly housing, which then allows you to run the engine while looking for oil leaking at the back of the rear main bearing.

Re: 1930 Model A diaper pan
Is the inspection plate under the floor board?

Re: 1930 Model A diaper pan
If your rear main bearing clearance being too great is causing your leak adjust your main bearings. Or ignore it and suffer complete bearing failure and the resulting cost, it’s up to you.

Re: 1930 Model A diaper pan
Hah!! I wonder how many have done THAT on their first oil change (and are willing to admit it!).

always check the easy stuff first we should not instantly jump to pulling the pan and checking bearings.
