I just pulled the pkugs on my 3.7l jeep engine. It was running like a box of rocks and I discovered two of them were leaking at the insulator.
However, do those plugs look like they are coming out of an engine that needs to be topped off with 1qt of oil every 400miles???? Sometimes there is a puff of smoke when the car sat for a little but shouldn't that amount show up on the plugs???
