[QUOTE="Wes Davis, post: 1014023, member: 62677"] I replaced my rear tensioner last weekend and did not make a difference. I am going to replace my front tensioner this coming weekend. I did some more research on this top end rattle and have read many examples that the problem could be as simple as using the wrong oil filter. I did recently changed my oil and I bought whatever cheap filter I could find. Apparently this v6 4.0 Explorer engine requires a filter with an anti drain back valve so oil always stays in the top of your engine when shut down. I picked up the Ford Motorcraft filter a couple days ago and it says right on the box 'silicon valve to prevent anti drain back' so I will install it this weekend and see if there is any change. It only cost $3.50 at WalMart. / [/QUOTE]
