New to Jeeps
So I have a 88 4.2 and yesterday I changed the value gasket and let the gasket harden over night. I got up this morning and started to drive it and everything was fine till I started to see some grey smoke come out of the tail pipe as i was driving. I pulled over and then it stopped. I have a link from the value gasket but do you think that smoke could be coming from the oil on the header?
