Engine =1996 4.0, XJ
Loud ticking sound from valve train.
intermittent, occurs regardless of cold or warm.
#3 plug carbon fouled, all others clean
new wire, cap/rotor.
engine has run Moble 1 5-30 synthetic for the past two years
Mileage is 116K
I have yet to run a compression test
With valve cover off, I watched valvetrain when running, all rockers are moving, all pushrods spinning
I just plugged a bottle of marvel in the crankcase and ran it up and down the freeway for awhile, no change.
If diagnosis is coorect, can I swap the lifters & pushrods out for new on cylinder #3 w/o worrying too much on cam/lifter?
My manual indicates there's a lifter removal tool that can be used to keep from pullnig the head - what's the consesus?
Thanks for your help gang,
Jon
