Lifter Change out
I am changing them because I Have a constant "Clicking" coming form the engine, I first thought or was led to believe it was "Cam Phasers" but then found out that my truck doesnt have cam phasers.
I have checked for exhaust leaks and cannot find any, removed belt and ran engine to eliminate Water pump, changed plugs and one injector and coil, I do not have engine service light on.
So I am down to replacing lifters and have purchased the tool and lifters which should be at my house when I get home. ( I work overseas)
I have replaced oil & filter with correct oil and Motorcraft filter. so failing the lifter replacement to remedy this issue, I would hope its not cam chain but once I get home end of month I shall tackle this job and hopefully get rid of this annoying noise.
