Stop that leaking rubber oil fill plug!

Hey guys,

I have long struggled with My rubber oil fill plug letting oil seep by and soaking my valve cover.

Well with inspiration from Matt1981CJ7, I took a few pics and wanted to create a post of one way to fix this as I could not find anything.

This is for fixing the issue when it is not caused by a bad PCV valve or excessive blow by.

Here is the rubber oil fill plug.
Ignore the time stamps



The parts, bolt, 2 washers,one rubber washer, nob or fly nut:
Washer should fit just the diameter of the very end of the plug


Drill hole through plug


Put rubber washer on bolt, followed by the washer.


Put bolt through the plug, then place the washer on and spin on either the fly bolt of the nob (many other options)



Finished.


As you turn the nob it pulls the washer up and tightens the oil fill plug.

I got all the parts from ACE hardware.

Nice solution, I'll have to put it on the to do list.

One thing I may add is to peen over the end of the bolt after the knob is put on. It's probably unlikely for it to loosen off after it's tightened down but it would be a real ***** to have the bolt and washers fall into the valvetrain.

^^ I thought about that, but the hole I drilled was was much smaller than the bolt, so it is very tight through the plug, you cannot pull it out by hand, I had to twist it out with an allen wrench .

Good Point though, forgot to mention that.
