I had an engine tick for a couple of weeks and thought , damn lifter is plugged or collapsed. So I put some Lucus in with a brand new oil change, didn't help.
So I was under the van this morning looking to see where it was coming from and found that the #8 spark plug wire was shaking a lot. I thought "the spark plug wire was loose and grounding out". NOT
It was the spark plug itself that had become separated and was clacking against the electrode. WOW, am I glad it didn't come apart, never had that happen before.Running quiet again.Yaayyy
