After I washed my Expedition yesterday took it for a drive to dry it off. Not particularly hard on it and it just began rapping loudly. Pulling in the driveway, open the hood and it sounds like its coming from the drivers side valve cover area at the front. My guess would be a bad lash adjuster?? introducing way too much slope in the valve train. But not ruling out rod knock or broken wrist pin after researching the lightning forums.
I did notice when I would pass anything on my left recently I would here some ticking reflected off the various objects but was not noticeable other wise. One of those "is that my vehicle?"
Took a video this morning upon cold start and you could not really hear anything until it is revved up some. Still cold so not nearly as loud as when fully warmed up.
