I did a rebuild on our H about a year ago and it seemed to be running well. I had it out today, but it sounded a little different, and there was a hint of a funny smell. I figured it was time for an oil change anyway, but when I drained the oil it was the horrible mix.
Is there anything on an H that could leak coolant into the oil besides the head gasket, and I suppose a cracked head/block somewhere? I'm thinking of blindly replacing the head gasket and see what happens. I'm trying not to contemplate a cracked core part. If it was a headgasket, would there be any visible indication when I take it off?
When I did the rebuild, I re-torqued the head after about 2 hours of use. The only odd thing to me during the build was that two sleeves were very loose on install. I coated them a bit with the Loctite sleeve retainer, and all the posts said the head gasket would hold them down once torqued anyway, although there seemed to be very little overlap of the gasket and sleeve. Other than that, I don't know what I could have done wrong.
Any advice that doesn't involve another rebuild? Can I run clean oil through for a bit and then change it and have it flushed? Should I check bearings somehow? The rods would be easy to get to, but I'd rather not deal with the mains.
