1456 Antifreeze Weeping

Just got done chisel plowing and then disking with our 1456. This is the first I have really worked it since we got it. It worked well, temp came up to 170 then cooled off as the sun went down. But after getting off I noticed on the right side of the tractor there are three streams of antifreeze weeping out between the block and the head. They seem to be right below where the exhaust outlets are. I checked the oil and it doesnt seem to have any antifreeze in it. Is this the sign of a blown head gasket? There is nothing leaking out on the left side of the tractor, just the right. Any ideas? Thanks

Run it for a few more days and then let it sit for a day. Pull the oil plug part way out Just hanging on a thread to make it leak a bit. If any coolant comes out first it is time. If not I would put inOne treatment of Subaru parts counter additive (it is a stop leak). It works really well. Jim

Sounds like the gasket leaking, my Oliver started dripping while plowing ended up blowing it out by the time I was done as the rest of the gasket went. Luckly all external...

It's not uncommon for 361/407 engines to look damp and even seep a small amount of antifreeze outward from the head gasket area when working them hard. Exhaust side and rear seem to be the worst areas.

My dad has an 806, 1206, 1256, and 1456. All are (hard) working tractors. Each one seeps enough antifreeze in at least one spot to attract dirt when doing tillage work. Scared the heck out of me when I first started doing field work. I thought I hurt his 1256 chisel plowing. 4000 hours later it still has the same head gasket. His 806 has 500 hrs. on a complete out-of-frame overhaul. They trued the block and head surfaces, and it got a quality, properly prepped, properly installed, and properly torqued (and re-checked/torqued) head gasket and it still seeps a bit when it gets a good workout.

If you can catch antifreeze in a container under the tractor as it pours out, or like Jim says, find it dribbling out of the threads on the pan plug, you have a problem. If you notice performance issues or overheating, you have a problem. If not, run 'er at 2400 rpm's, midway or less on the water temp. gauge, and 1200 degrees or less at the exhaust all day long.

I know what you mean it scared me too, all I have done with it before was spread manure and that doesnt really work it and it never leaked. But sinking in the 9 shank chisel and then running a 12 foot offset disk seemed to work it. Im letting it sit now so I will check the drain plug tomorrow and let you know what I find. Also the regular temp gauge does not work but I have an aftermarket one on it. Like I said it runs around 170 is that about right?

agreed, have lots of hours on old 1066 and 1466, check oil and antifreeze daily. could be a little warp in the head or a couple of pits in the block. don't put a torque wrench to it, probably make it worse. keep an eye on the water pump too, not much of a pump for as big as the engine is imo.

Stock thermostat opens at 175 and is fully open at 190. If you're gauge is functioning correctly, you don't have it warmed up yet.

Well I checked it last nite by opening the drain plug just enough and no coolant came out, just oil. Also the coolant level was good, didn"t seem to be too far down. I still left it sit and will check the oil again tonite. Where can you get the Subaru parts additive? I"m thinking of trying something in it just because I hate leaks on tractors. One other thing I want to get the stock gauge cluster back in it. Any reputable parts for IH other than the dealer, I think the price from them was over 280 or more for the gauge I need.

Subaru parts counter at a dealership. or on line probably. This site has them in stock. I would also try Bates
one source of many

The only thing I can find is listed below, is that what you are talking about? Ive also read about peppper working for radiator leaks, but will it work for a head gasket?
