I mentioned the bit of oil I found in the dip around my spark plug a few months ago, today I saw this bubbling:

Should I be worried?

IMO, I don't think it's a big problem.

If it bothers you, let the engine cool down completely, then remove the spark plug and wrap its threads with a layer of aluminum foil, then re-install the spark plug.

Never fully tighten a spark plug into a hot cylinder head or you run the risk of having to heat everything back up later to remove it.

That's not a big deal. Fairly common a on a T. It sometimes happens when you rebuild an engine and clean up the threads on the head and so on. Or in other words cleaning them up to good.
Good idea just using a wire spiral brush when cleaning up the plug holes if you think it needs it.

Using foil is a trick that usually works.

The T spark plugs are taper threads so just tighten them up to stop the leaking but like Mark said best when cooled down. Snug up all four a bit till your leaking stops. A little at a time it doesn't take much.

Sure, instead of oil bubbling, it will be never seize bubbling, big improvement! :-O

foghorn

Mine did it and I tried the aluminum foil. It worked great. No bubbling now.

Thanks guys, you've put my mind at rest no end. Bit worried about fragments of tin foil dropping down into the cylinder though, would plumber's PTFE/Teflon tape be OK?

The shell of the spark plug is grounded through the contact of its threads with the cylinder head. Aluminum is conductive, PTFE/Teflon tape is not. The threads might cut through the tape and provide electrical contact, but why take the chance?

Of course, now dozens of folks will post that they have used Teflon tape for decades with no ill effects. :-)

Ah, good point - thanks!

I do the Teflon tape all the time. The threads cut thru the tape and ground the plugs as they should. You only need one wrap around the threaded area, not several. Just did one yesterday, she's banging on all 4. I had wrenched down the plugs good and tight but was getting blow by on all 4, added the tape, good to go.

Thanks for the testimonial, Mark. :-O

With all the drama lately, I recall a thread in the distant past that the all purpose solution is Bitumen roofing tar. I believe the poster was Hugh .... Well I guess I forgot his last name.

Tin foil is one of the good solutions in addition to the Teflon single wrap.

John: I miss Hugh too. The good old days. Dan

Me too :-(

Was fun about putting tar to its proper uses, so little respect for that thick stuff or for Hugh.

That roofing tar is better than Windex for zits too!
