I have a 2001 Jeep Wrangler with the 4.0 engine. It has 56,000 miles. When starting the engine there is a loud rapid ticking noise that last until the engine warms. It only does this when starting a cold engine but not every time, maybe 3 or 4 times a week. It first started doing this a little after 30,000 miles and then it stopped and now it's doing it again but more frequent. If I end up replacing the valve lifters does anyone know of a good place to buy the hydraulic lifter removal tool? Is this tool really needed or could I get by without it? Also will I have to remove the A/C compressor? The book wasn't real clear on this part of it. It didn't say anything about removing the A/C during the head removal procedure but did say to recharge after assembly. I like to know what I'm getting into before I start. I appreciate any help.
Thanks, Dennis
