A quick update on the Okie Farm Jeep. Some history- my engine was ran quiet and started right up but lacked power. It also had an intermittent miss on #4. Compression checks showed 50# in 1,2,3 and only 20# in 4 when dry and only slightly better when wet. I was pretty convinced that it was broken rings. I tore the head off and confirmed this. A look at the valves also found #4 was pitted on the valve and not sealing well. Lastly I bent #1 Exhaust valve ever so slightly getting the head of the engine. The head had become one with the block and that was a story in itself. The trash (carbon) you see here is from cutting the ridge off the cylinder. The photo I took of the number 4 exhaust valve was not very clear but you can see the problem. Luckily, everything else was good- no problems with bearings or the rest of the ratating assembly. I was also glad to find the bore was standard and that makes me feel better in case I ever need to have it bored I have room to work. The valve seats were in good shape as well and after a quick lap all the valves sealed right up. All the work was done with the engine in the vehicle. Plasti-gauge showed everything was tight so after honing the cylinders and a good cleaning it went right back the way it was. Fired right up and took it for a short run to seat the rings. Quick re torque and check of everything one last time and my wife and I took it to town to get feed us and the chickens. It just feels right backing up to the feed and milling company and getting feed- like it was an ad from the 1950's.
Runs like a sewing machine and now as so much more power. I can accelerate up hills I used to have to down shift on. Today I took a new compression test and I have 105 # across the board. I think that may improve a tick as the rings continue to marry with the cylinders. All in all I am a happy camper and this is one of the cases where a total rebuild was not needed. If your engine runs / sounds good- has good oil pressure and just lacks compression- this may also be a possibility for you.
