[QUOTE="SRQ941, post: 441953, member: 22320"] I got a 2002 Grand Cherokee 4.0. When I bought it it just sounded like a lifter tic. After a couple weeks I went to change the oil and what a surprise I got. 13 quarts of oil I drained out. Yep you read it right... 13. At the right amount the tic become a slap. I replaced the timing chain and gears. Still slapping so I dropped the oil pan. Piston skirt everywhere. Now when I put in new pistons and rod bearings (same rods.) I tried to turn the crank after getting 4 pistons torque down at 33 ft/lbs and it is locked up. I back the nuts off a little on the last 2 I dropped in and the crank turns fine. What have I got wrong? I'm just an old shade tree type mechanic with no shop and a bunch of wrenches. [/QUOTE]
