Bubbles Around Spark Plug

Hey All. Well I did a search but the bubble issue was only a side part of a past post. So I have a F 134. I just fired her up and noticed bubbles and pooling fluid at #2 spark plug. Jeep runs every week but I have never touched the spark plugs. No leaks seem to be coming from above so I do think it is at the plug threads. Oil level was low not high and I opened the hood only after the engine was started for about a couple minutes when I noticed. So I guess the question is what are the steps I need to take to diagnose? Whats stinks is that the Pioneer Garage here - Jeep service station started in 1941 finally closed its doors so anything overly technical is going to be a challenge! Snow storm coming in tonight so I am not going to do anything now but I am guessing I am going to have to do some work soon. Thanks folks!

 

I'd suggest seeing if the plug is screwed in snugly, with a spark plug wrench or socket. (13/16")

Possibly replace it so as you'd have a good new gasket-washer under it. Heck, replace all four while you're there...

 

ah ok - I don't know when - if they were ever replaced!! When I first got the Jeep I brought to mechanic and told em to go through it all.
Definitely - might as well do em all. Dumb question, is there a name brand or 'type' that I should get? I am in the hole with this thing so might as well do it right not dirt cheap at this point. Thank you! Cheers.

 

I got a set of (4) AutoLite plugs from Quadratec awhile back that were pre-gapped to .030 for the F134 but I double-checked them anyway to make sure they were gapped correctly. They were right on!

 

its common especially on the flatheads to notice them bubble. Its just the crush washer not sealing. Sand the sealing surface a little if its rusty usually fixes it.

 

Thanks guys!! I was trying not to panic too much but also wanted to address the problem. Appreciate it! Will give it a go after the snow storm. Cheers

 

While on the subject - any tips/tricks in changing the plugs? Aside from throughout inspection of seat - maybe some light sanding. How do I keep stuff from falling into hole. Do I need to worry about that? Any anti seize on threads, etc. I just ordered actually from Summit - I couldn't find Autolite on Quadratec.
Thanks again!

 

Replace plugs, I use whatever brand is on sale at my local FLAPS.
clean around plugs as best you can. Retighten after hot and cold cycles a couple times.
My 134 came with plug foulers installed, another place to leak. I've since removed the dang things. Check valve cover for leaks.

 

Use an air gun and blow the dirt out from around the spark plugs. Wear safety glasses to keep the dirt out of Your eyes.
Just Be careful with the air gun.

 

Loosen them but don't take them out,don't want any trash in hole.
Use air, scrape with screwdriver , gun cleaning bore brush in hole, or if u have a thread chaser cleans the threads and hole?

 

Awesome...! Yeah as I get older I am now much more conscious of eye wear ear etc. So good good tip there! Not taking them all the way out is also a good move. I am reading never seize on these when they go back in. Any of you guys think that's bad or good? Simple task here but there are always some small details that experience helps provide. Thanks a million. Cheers

 

Never seize in small amount is great!
Barley wipe on threads!
Especially with alum heads!
And on lug studs!

 

The tireguy from work says no never seeze on lugs oil em. Swears they can loosen with never seeze something about torque.

 

brush around plugs with a tooth, or bottle brush and use compressed air (compressor, or computer blaster), lable and remove wires from plugs, but not dist cap, loosen plugs a couple turns each (all of them) and crank the motor over. Compression will blowout any loose material.
Gap and reinstall plugs(a little oil is fine). Hand thghten to make contact and use wrench to further tighten 1/8 to 1/4 turn more. Reinstall wires in correct order.
If engine ir running rough may be time to think about rotor, points and cap.

 

Autolite 295 or Champion J8C. Available just about everywhere.

 

In fact any hardware store, in the lawnmower parts.

 

Budd wheels you can use never seize but not on hub pilot use a couple drops of oil on the threads and the washer

 

Xactly what he said I just oil em all.

 

My bad ,oil might be better?
Anything to fight rust and lock up? In small doses?

 

Yeah, I never-seized 'em one time only and won't ever do it again.
