Hello I have a 94 explorer with 150k miles. I change the oil every 6000 miles because I put about 1000 highway miles a week. When I start the car in the morning it sounds fine as it idles. If i jump in it right away and drive down the road, I here it tapping or ticking away like a old manual typewriter. Once the engine heats up 5-10 minutes everything is quiet again.
Question: Could I use a motor flush, is it a sludge buildup.? Ignore it. Add some snake oil voodoo juice to the oil.?
