I need to chase a coolant leak, on my CA. I have been putting off, head work for a year now, (always needed the tractor for something), I found it 3 qt's low on coolant, yesterday, and added it before using it on the bush hog. That caused me to pull the dipstick and look at the oil. the oil was grey, which makes me think water. So I am going to pull the head, and do a valve job, and have the head checked for cracks. If it is ok, then I have to look for sleeves leaking. If I have to pull the sleeves, then I might as well buy the YT kit, with the sleeves, pistons, rings, and bearings ECT. It was 1989, the only time I have had to overhaul a AC B 125 motor, and don't remember, where the sleeves seal at. Top, or bottom? are the seals provided in the kit? With my poor memory, I should get a real mechanic, to help, but think I should be able to do the job. Hopefuly, some one will answer my seal question!
