93 Wrangler YJ 4.0, with 112000 miles on it
Did a cylinder comprestion test due to running hot and a small miss tried everthing else.
Front cyl 185,2nd 190, 3rd 190, 4th 195, 5th 195, last 130 dry 170 wet.
The last cyl closest to the firewall had a fowled plug.
Could it just be rings any way to fix easy or is it a cracked head, Oil is good no water, Rad is full no loss of water,
The temp gauge only raises when im driving it. It can idle all day and not get hot.
