dieseldoc Posted January 13, 2015 Share Posted January 13, 2015 Is there a recommended interval for timing chain replacement, either by ford or your guys experience? My sister has an early 2000s f-150 and she asked me if this needed to be done. As I am not a gasoline guy I did not have an answer for her and thought I would ask the experts.

8WA Sman Posted January 13, 2015 Share Posted January 13, 2015 I don't know of a posted interval. In my experience the 2 valve 5.4L will leak oil from a head gasket, burn oil because of valve guide wear, or break a valve spring before the timing chain has a problem.

Keith Browning Posted January 14, 2015 Share Posted January 14, 2015 The timing chains are a non-maintenance item. Quote Link to comment Share on other sites More sharing options...
YukonTyler Posted January 14, 2015 Share Posted January 14, 2015 I have never replaced one preventatively. Conversely, most of that vintage are not in solid enough condition to make that particular job make financial sense. Quote Link to comment Share on other sites More sharing options...

nelsona19 Posted January 28, 2015 Share Posted January 28, 2015 I change out my chain tensioners on my 05 f150 about every 40k, seems to be the magic number for the gaskets blowing out. Quote Link to comment Share on other sites More sharing options...
cbriggs Posted January 31, 2015 Share Posted January 31, 2015 Anytime I have seen problems with those chains the engine is usually in the same shape. I have an expedition with a broken rh fixed guide. The rh cam seized in the head after it went 43,000km on an oil change, cam broke loose again after the guide broke.
