Oliver S88

[old]

Well the last 2 years I have been fighting and overheating problem and now it has coolant in the oil. Haven't drained it yet to see how much I just know the oil is milky. #4 cylinder doesn't seem to be running correctly so is it likely to be the head gasket or maybe a sleeve seal. I've never heard of sleeve seals being a problem with an Oliver but I guess it can happen. I also have to replace both front tires and tubes for a total of $164 each mounted

Is there a question in there? Yes, those o rings on the sleeves can go bad. I bought a Super 55 cheap because they were leaking on that. I can't help you with the price of the tires.

If it has been overheating for two years it could have done damage in several areas, including the liner seals. Likely a full overhaul would be the best path and may be needed.

$328 is about what I would expect a tire shop would charge for 2 tri-rib fronts, tubes and mounting. Brand and ply of tires they are selling you might change the price a bit. I surprised you aren't just going with a couple used light truck tires, unless they won't clear, no more than you use it.

I'd probably go with used truck tires if I had any but I don't.
As for the engine it has always run strong and it didn't have coolant in the oil when I moved it out of the field so this just started. I know #5 plug has been fouling for a year or more so figure head gasket but only opening up the engine will tell for sure

Like I said in your other thread, rebuild it.
