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!
