48 8n smoking from oil fill

gac1218 · Dec 18, 2014

I had a short in my wiring and melted a few wires. It wouldn't start until i isolated the wires and retaped them. Then after about 10 minutes of it running fine, I hear a pop and then smoke starts to come out of the oil fill. It seemed to not lose power but I fear there may be engine damage or could it be a melted plug wire or something simple.

"....or could it be a melted plug wire or something simple."

Beats me.

But if you're having to tape up a wiring harness, I'd say it could be about anywhere.

Time to pull out the old crap & fix it.

Check out tip # 42.

About $20 for a new harness & you won't have wiring problems ever again. Add another $20 for plug wires. (see tip # 27)

" but I fear there may be engine damage "

Probably not. But the next time it could easily catch fire.

I was planning on replacing all of the wiring. It all went crazy when the voltmeter shorted and started sparking on the tractor frame. Hoping the smoke is from one of the plugs not firing because wire may be melted? But, I really have no idea what us causing it.

What caused it was bad wiring. Means
you're going to replace all the wiring,
the specific cause is academic at this
point.

6 volt or 12 volt?

Does it really have a voltmeter? Or is it
the OEM ammeter?

BTW......if you're in for a dime you're in
for a dollar......you might as well get a
new battery cable & strap.

By oil fill, I assume you mean breather. That's blowby, kinda normal on an old flathead especially after warming it up 10 minutes. Doubtful any wiring caused it. But, for future reference, the words re-tape and wire shouldn't be in the same sentence, unless you are trying to combine the words flaming tractor of doom. Lol.

Sounds to me like blow by on one of the pistons. If there is smoke puffing out of the oil fill, the smoke would most likely be coming from inside the motor, if it is inside the motor, I doubt you have a fire in your oil pan, so that leaves inside your cylinder (where the fire should be), but instead of coming out the exhaust it is pressurizing the block and coming out of the oil fill; bypassing the rings and called "blow by"...

Hopefully I am wrong.

Plug wires aren't hard to check. Can simply test to see if it is
banging on all 4 by removing one at a time down the line. Each
should make about the same difference in change of engine
sound, if you pull 1 that makes no diff, that one ain't firing for
some reason.
