Hi there !
My name is Thibault, and I live in France, near Paris!
I have had an 89 4.0 XJ jeep for 2 years!
I have a noise from the lifters ... the famous lifter ticking noise ... so yeah, I know, these motors are famous for making that kind of noise, but all I hear is that and it drives me crazy !! So I changed the lifters, push rods, the piston rings, the connecting rod bearings… pistons are ok, no piston slap or rod knock… I let the lifters soak in oil for several days before install them, and everything is tight to the couple! I start the engine, and… still this noise… tick tick tick… I have a little low oil pressure… so I decide to change the oil pump… always the tick tick tick… the rocker arms maybe !? I change them… and… tick tick tick… the engine runs on 10w40 oil! The noise is quite loud when cold, and much more discreet when hot! When I changed the lifters, I didn't notice any particular play in their housings, and the flexplate bolts are not loose! Do you have other leads to follow?
