Change the oil or not??????

[ghobbs]

Hi folks,
I have a very nice totally rebuilt from the ground up 1952 Ford 8N. I accidentally left the fuel on last week when I turned off the ignition. I just noticed this yesterday when I started up the tractor.

My understanding is that the fuel will continue to drain down into the engine if it is not shut off. My question is, if all this fuel has drained into the crankcase, should I go ahead and change the oil before running the tractor or does it really matter?
Thx!

I would change it. Cheap insurance. .

You're talking 6 quarts of oil, no big deal to be safe. Go for it, and change it. I have a 52 8-n also, a nice machine.

May I suggest you get a start up and shut down procedure for your tractor and check each item off, at least until you have gained some experience with your tractor.

The way I'm reading your post, you started the tractor without checking the oil level on the dipstick. Bad procedure. If the gas drained into the crankcase and contaminated the oil there would be a high oil level, depending on the amount of gas the tank contained.

Just because you failed to shut the gas valve off doesn't mean all the gasoline drained into the crankcase. For that to happen the needle valve in the carburetor normally has to leak. That's a common problem but not all do.

So check the oil level and change it if it's over full. If there is a question in your mind about a higher level, change it as stated in other replies.

AGREE 100%, what is a few quarts of oil compared to the "what if"....

Just FYI, every time I have purchased a used car, one of the first things I do is change the oil and filter. Makes no difference if it was just done. I do it anyhow so I KNOW what is in there....:thumbsup:

I've never heard of that. Is the carb above the intake manifold?!

I have a Ford Golden Jubilee and I'm almost 100% sure the gas can't run up hill into the engine. :laughing:

If you are really worried about it change it.

The guys above with their checklists need to chill. Your 8N has made through 60 yrs already... I doubt you are gonna hurt it.

And you'd be 100% wrong.

gas tank is perched OVER engine.. gas can fill carb, fill air cleaner tube and spill over into manifold too.


can happen.. doesn't always happen..

to the op.. check the dipstick.. is it overfull?

I went ahead and changed the oil. The dipstick wasn't over the full mark but I certainly could smell a lot of fuel on the dipstick when I checked. Yeah I was told by an old 8n owner that fuel will run into the engine if I dont shut it off. The weird thing is that when I got back from my week long trip and realized the fuel was on, I started it up and lots of smoke bellowed out the exhaust and then the engine died. There was no fuel in the tank. I could have sworn I had some fuel in it before I left. Anyhow, changed the oil. All is well. Hard to beat these nostalgic American Icon tractors!! I owned an 8n about 12 yrs ago and rebuilt it then sold it. For years I wish I didn't sell it. Now I have this one rebuilt from the ground up. Purrs like it just rolled off the assembly line.
Thanks for all your responses!

That would be one heck of a leak to push up into the manifold. Never heard of that happening before...
