Big danger is . . . once it sits for a while, and you start it back up, you apt to get some pure water through the oil pump and then spin a main bearing. So, if you go to start it again, pull the drain plug out and drain off any water first. I was a Deere mechanic for a long time, and I don't believe I've ever seen one leak coolant into the oil from a bad head gasket. I can also say that I've NEVER seen a head bolt fail on the little 152 c.i. engine, and I don't replace them. Now that engine, originally, only had one o-ring per sleeve and they were chronic leakers (water into the oil). It got fixed later with the 350Bs and on with added o-ring grooves in the block itself. So, new liners for an old 350 are considered an "update kit" and come with added o-ring grooves on the liners themselves converting it to a three sealing ring per sleeve engine. Hopefully, that is what you installed. Once that's been done, and done properly, they last a long time. In fact, I've never seen one torn down due to leakage, just for routine rebuilds when worn out. We DID have similar problems with the larger engines getting pinholes in the sleeves from cavatation. I assume your crawler doesn't have any extra engine oil coolers added in the radiator, or under the oil filter - so it sounds like a tear down is in order. If you pull the pan, you'll see the leak right away if it is a liner.
