Hello. First I want to thank everyone who answered my compression question so quickly and knowledablely. You guys are the best! (Please see "What does "No compression mean?" thread for a refesher) Anyway, today after work I torn the engine down to the cylinder head gasket and there was indeed a 1/2"+ gap between the 2nd and 3rd cylinders. So tomorrow I shall replace that gasket plus the intake/exhaust gasket. But I have a few quick questions which hopefully some of you guys can answer before I head out tomorrow. I am worried about damage elsewhere as the Jeep got driven 3-4 days after it began misfiring but only at low speeds (20-30mph) and only like 20 miles total over the 4 days. I don`t see anything that looks bad. All the push-rods are straight. No visible problems with the rockers, springs etc. I put it in neutral and turned the crank with a ratchet and all the pistons move up and down with no noticable resistance or problem. The #1 & #6 go up together. The #2 & #5 together. And the #3 & #4. I am assuming that is the correct pattern? As long as I have this thing apart what else should I do? There`s a bunch of carbon on top of the pistons. A lot of the push-rods although they are straight are covered with a crusty black substance which seems to come off if you spray it with parts cleaner and use a rough scrub pad (Not steel wool those green pads)..Any input before tomorrow will be greatly appreciated. I am a rather poor soul and it would be wonderful if I put this back together and it runs good.
