V-8 is supposed to leak ?

[whizzernick]

I have been told that ford V-8 engines were designed to leak a tea spoon
of oil when turned off. (model A's too ) I was told that the oil at the top of crankshaft (slinger ) is meant to drain to the front and the back side of crankshaft in between flywheel and block. That is why a large cotter key is at bottom of pan so as this hole (oil drain hole ) is always clear. I do know that most fords leak.

The oil drips to keep the cotter key lubricated, so it doesn't seize in the hole.

That it does Don't believe the Ford V8s were designed to leak, it's just a factor with the technology available at the time and the age of the engines. The slinger rear seal is prone to leaking under a lot of conditions!

They should not leak, my 33 did nearly 7000klms the other month towing,never leaked,

You all of course know where this is going...

I was told it was to keep the cotter pin from 'Squeaking'

I rarely see a drop on the ground under my A when i park in driveway or parking lot, but there is some seepage and oil wetness on the bottom-----

That of course "Depends"

I always thought of it as the "self undercoating" option.

Dual purpose, ah Henry thought of everything

[Talkwrench]

Lawrie check your oil.. you know the story ..lol

Over filling will cause the rear main to leak.
Also to thin of oil. I use 20/50. G.M.

Condition is the big factor in whether it will leak or seep. An engine with a pan rail or road tube vent will drip if there is a lot of blow by. Worn main bearings and old gaskets also lead to some spotting. Transmissions can seep too over time so a person has to smell the oil under the clutch housing to see which it might be. I've always felt that the drain hole cotter pin was simply there to keep the drain from clogging up by movement of the pin.

Whoever told you that was making stuff up to sound important, was just messing with you, or was repeating nonsense out of ignorance! "designed to leak a teaspoon of oil when turned off"??? Did they explain why? Could they explain why it was a teaspoonful and not a thimbleful, or a tablespoonful? You could fill a book with all the fanciful urban myths surrounding old cars!
Old engines did leak some oil, true, as the technology for leak-free engines wasn't up to speed yet. But to claim that they were deliberately "designed" to leak a specific amount at shutdown is nonsense!

This is true, but the Catch 22 is that the cotter won't move in the absence of oil.

model B engines have that large cotter pin too, Under flywheel?, why do these engines need that cotter pin? To release excess transmission oil? Fascinating, these oil engines are works of art.

Frank, you miss the point. The cotter pin requires opinions, not questions.

[whizzernick]

Yes:::::: I do sell a fix to the oil drip (not leak ) problem. (DIAPER) From your answers to my question (ford barn people that reply to posts) I find that your cars do not drip or you don't care if they do . Or you use cardboard or you just like the oil mess on your floor. I don't and I just got tired of the clean up. (THAT IS HOW AND WHY I CAME UP WITH THE DIAPER)
My question was simple (I think ) but 12 people chose not to answer my question.
I am sorry I chose leak and not drip in my question. I have sold 5 so far and all are happy that the floor is not stained from oil drips. One brave man just ordered a second one and would like it to also include the transmission . ( they also sometimes drip) Also: yes I am getting rich from all my sales. and if you believe that I do Have a bridge to sell you

[40 Deluxe]

I'll take that bridge if it includes free shipping!

I said the large cotter pin is there to release excess transmission oil, what did I do wrong?
