Tinker please elaborate on the cotter pin
Tinker: please elaborate on the factory purpose of the cotter pin in the pan.
Have snagged a few sleeves on them and gashed a finger once. I always thought it was to help flow oil drops away from the pan. |

Re: Tinker please elaborate on the cotter pin
Your thoughts are correct (along with keeping the hole from clogging).

Re: Tinker please elaborate on the cotter pin
You have it correct. The pin will rattle in the wind when driving, keeping the hole open for oil to be removed. That part of the pan is separate from the actual oil compartment. It is under the clutch and expels any oil that gets past the rear seal.

File off the sharp edges. Might save some blood and a shirt or two.

Re: Tinker please elaborate on the cotter pin
no rear seal --- only slinger ---Im told that the only time oil gets in that area is when you shut down eng . that amount comes from rear slinger about 1 tea spoon.

Re: Tinker please elaborate on the cotter pin
Shouldn´t come any oil through the slinger when you shut off the engine.
Climbing a real steep hill or engine blowby is what can have oil come out into the clutch area. |

Re: Tinker please elaborate on the cotter pin
Mel i don't know. I know the pin is there to get rid of excess oil from wherever.
if someone says their original flathead doesn't leak a little oil. they are probably exaggerating. Last edited by Tinker; 08-19-2019 at 06:37 PM. |

Re: Tinker please elaborate on the cotter pin
yes rear seal on pan -cork -- also seal on oil pan edge . this is what I have been told :
when you shut down engine the oil at the top of slinger --- some goes threw tube into oil pan and some goes into clutch area. PLEASE CORRECT ME IF I AM WRONG I have (4 ) 33-34 fords --- they all leak, always have. I now make a diaper that catches oil NO MORE MESS ON FLOOR (see ad in V-8 times) I do know that 49-53 has no cotter pin in oil pan NO SLINGER but uses a rope rear main seal . I am also told that they (49 -53 ) leak |

One last thing. On the last engine that I did, I experienced lower than normal oil pressure, which I traced back to the use of a Speedway Motors oil pump. I removed the pan and replaced the oil pump with a known good Ford pump and solved my oil pressure problem. Upon re-installing the pan (it had not been on the engine for more that a few weeks), I had a slight rear oil leak. I was real careful, but it seems that these gaskets and seals are not re-usable. I'm waiting for Rock Auto to have another close out on "obsolete parts" so I don't have to pay an arm and a leg for the pan gaskets. I'll probably end up "biting the bullet", though. |
