Nope, the lifter push rod holes aren't big enough, nor does have a

Re: Gasket Questions
What kind of noise does a "noisy lifter" make? I'm curious because my '02 TJ
4.0 has an intermittent "thunking" sound (with accompanying vibration) at
idle. I've no idea what that could be, and because it doesn't consistently
do it I haven't been able to take it to a shop.

Re: Gasket Questions
It makes a tapping/clicking noise. A valve only opens once every second
engine stroke so a valve tap is slower than say piston slap which
happens every stroke. If you put a timing light on, the valve will tap
every second flash.
Some of those 4.0 engines do suffer from the occasional piston slap when
cold. This won't hurt anything and cannot be repaired without a total
engine job.
