97 wrangler valve lifters...
 

2.5l, '97 wrangler, valve lifters....do I need a special tool to remove the
lifters? Where do I get it? Will the lifters come out without removing the
head? I know I could use a magnet, but there is probably some varnish on
the lifter. I have some rocker arm noise, will replace the rocker arm, push
rod, etc., and would like to replace the lifter also...

thanks

According to my 2000 FSM, the 2.5L 4cyl does not require removal of the
head, but you do need a "Hydraulic Valve Tappet Removal/Installation Tool
C-4129-A."

Should be similar to this tool.

Check your local AutoZone to see if they have one in the
loaner bin.

Teloscoping magnet is the tool, good luck finding a lifter removal tool
none of my area parts stores have them (Advance, Autozone etc.).

That said don't change your lifters, Cam's and lifters should be
replaced at the same time, they wear into each other developing unique
wear patterns and unique patterns of work hardening (which is a lot like
forging metal) on both surfaces. A new lifter (or vice versa a new cam
while reusing old lifters) can quite possibly eat a lobe (or lifter face).

Imagine it this way... that old lifter has been sitting on the same Cam
lobe for thousands of miles, the shoulders and face of the Cam lobe are
slightly rounded and the face of the lifter is dished, these surfaces
are WAY HARDER than when freshly milled... Your new softer lifter is not
dished... that means the Cam lobe is contacting the new lifter only on a
tiny POINT, Cam lobe AND lifter face is going have extremely accelerated
wear. Because the same lifter preload and spring pressure are being born
on a MUCH smaller surface area, one side of which is MUCH harder than
the other.

Don't ask me how I learned this... Lets just say that it cost me the
price of a nice set of Crane anti-pump up lifters (64 bucks), as the
stock Cam shaft had 140k and was going to be replaced anyway.
