Is it time to rebuild your Jeep’s axles or install a locking differential? Does your CJ need a frame-off restoration? If engine, transmission, transfer case, axle, steering, electrical, or metal restoration seem difficult or beyond your skills, here is the fix! Jeep expert, automotive instructor, and author of the Jeep Owner’s Bible, Moses Ludel simplifies the most complex service procedures and recognizes the most popular performance upgrades.
Moses Ludel learned to drive in his parent's 1964 CJ-5 Jeep. Dirt roads soon led to rural Nevada's ghost towns, old mine sites, remote dry camping, gold prospecting, untamed trout streams and primitive hunting areas. An outdoor enthusiast devoted to off-pavement safety and low-environmental-impact use of four-wheel drive vehicles, Moses is an expert at vehicle recovery procedures, survival driving techniques and protection of a 4WD vehicle under the most challenging off-road conditions.
I need to replace one piston (#5) in my 1986 CJ-7 258 cid engine that was damaged when the tip of the spark plug broke off. I want to replace it without removing the engine and need guidance in determining if I should get oversized rings/piston, or else order the standard size rings and piston. There isn't a ridge at the top of the cylinder and there doesn't appear to be any damage to the cylinder wall. The engine had been rebuilt in 2002 and has approximately 10,000 miles on it. would this manual provide me with the proper torque specs for re-installing the head, intake/exhaust manifolds, and oil pan, as well as the acceptable bearing tolerances for the piston rod to crankshaft? Thank you!

Mike you got all kinds of stuff going on here. I'm going to try and answer these one by one. If you are not boring the cylinder I see no reason to use oversize rings/pistons. But I can't see and touch what your working on so take this all with a grain of salt. It's a 10 year old rebuild with only 10,000 miles. If everything else is good I don't see why you couldn't use a stock size ring and piston. As far as this manual it is worth every penny. Moses Ludel is the be all end of for anything CJ. Not to mention there is a lot of pictures and it is laid out really easy to understand. It does have the torque specs and tolerances in there. I wouldn't attempt any kind of rebuild with out this book. It's worth every penny.
