> I have a 1997 Ford Ranger with a 4.0L motor and 31K on the clock.
> Lately, when the motor is dead cold (like in the morning), I've
> noticed a loud tapping from motor during idle that sounds like a
> sticking lifter. If I step on the gas the noise goes away and it
> also stops after the motor has warmed-up for a few minutes.
> Oil pressure seems ok, judging from the brain-dead factory gauge.
> I was kinda surprised with this. My old Ranger, a 2.9L, ran fine
> with 145K when I traded it in so I wasn't expecting trouble when I
> bought this truck with 22K.
> I did a little digging on the web and found this nugget:
> "Certain castings of 4.0L engines produce a dieseling sounds which
> appears to be a tapping lifter. This noise is not created by Fuel
> Injectors and is an engine problem which Ford is aware of."
> Any truth in this? Besides this annoying problem, the truck doesn't
> burn a drop of oil and seems to run fine. I would like to keep this
> vehicle for awhile but this tapping when the motor is cold doesn't
> inspire much confidence in me.
> I was curious if anyone else had this problem.
