[QUOTE="SlugSlinger, post: 3446581, member: 7248"] Well, I’ve been busy with the Jeep. A couple weeks ago I heard a knocking noise just off idle. I drove the Jeep to my buddies shop to find out that the noise was a bearing knock. I drove it home and began removing the engine. I took the pulled motor to the shop and we pulled it apart to find the number 5 & 6 rod bearings had spun. We believe the spun bearings are related to the cracked heads because number 5 was the hole throwing the misfire code and had coolant leaking into the cylinder at night or whenever it sat for some time. The crank cleaned up with a .10/.10 cut. The two rods were replaced and new lifters and pistons were purchased. [ATTACH=full]178367[/ATTACH] The cylinders looked good and the factory cross hatching was still visible. [ATTACH=full]178366[/ATTACH] He ran everything through the parts washer a few times. He honed all the cylinders to clean things up. I disassembled the heads, that we just worked, to clean any contamination out. I also cleaned up the castings on the exhaust ports. [ATTACH=full]178368[/ATTACH] [ATTACH=full]178369[/ATTACH] He started getting things back together today. Tomorrow he’s cutting the cam gear to index the cam. [ATTACH=full]178370[/ATTACH] [/QUOTE]
