2-70 White head gasket problems

jacot14860 · Nov 29, 2017

I have a white tractor (2-70) blowing coolant out of radiator. Doing an in frame now, after i replaced head gasket twice, had the head checked twice and shaved straight. It still blew coolant out of the radiator. Does anyone know what the liner protrusion should be? I need to get this tractor going thanks for any help.

Did you check if the block is flat? What brand of head gasket?

......had the head checked twice

Pressure tested?

Not on a tractor engine, but I had an engine with a crack around an exhaust valve that behaved how you describe.

Did you put new sleeves in it? If you did check the sleeves about 1/4 " down from the top for cracks. The new sleeves aren't made as good as the originals.

In the process of putting new liners in. I have to
shim three of them

Two machine shops both pressure tested head

I do need to check for straightness if deck. Good idea thanks. I think it?s a reliance in frame kit

too much coolant??? seams the olivers like radiator fluid tank half full/empty.

Might also want to check the radiator (just for good measure). Had a 1650 come in for repairs and after running 20 minutes it would boil over. Problem was calcium clogged all the internal tubes inside the radiator, coolant had no where to go except out the cap.

This tractor is eminently after starting. Thank you any help is appreciated

jacot14860 · Nov 30, 2017

Maybe but it does seem that it shouldn't push it right out after starting the tractor hmmm....

Is there any common problems with the 283 diesel?

I have had a issue close to yours with a reliance head gasket except it was bubbling compression out while running. The only reason I saw it was one of the fuel return tees was leaking fuel and running down on the head gasket. Mine wasn't leaking compression into the coolant that I know of it didn't run long enough to find out. I got a ago gasket coming and will let you know what I find when I get it apart. You could try to warm it up and re-torque it but I have never had luck with that. I think the reliance gaskets have a lot of room for emprovement. And this was on a complete OH for a 1655 all sleeve protrusion were in spec on mine.

wilma · Nov 30, 2017

When you took the head off, did you notice where the head gasket failed, (i.e. in between cylinders)? Did you have any coolant in the oil pan? Did the engine get hot or very warm (normal heavy work under load) and then you noticed it boiling over? These are some of the things I've run into that can lead to gasket failure as these engines can be sensitive to over heating...(have been guilty of it myself). One other question, is the deck pitted around or near the fire ring on any or all cylinders?

Sleeves can crack or pit.

Call Maibachs Creston OH. Last time I got a head gasket for my 283 they had a couple different choices depending on liner height and other measurements.

My 1655 started to show a preference for a lower coolant level about four years ago after it went in for a clutch job, which required pulling the engine. Ever since it likes to run the coolant level at the bottom of the top reservoir, right at the top of the cooling tubes. It didn't used to run that low. But now if I add fluid to get the level up into the reservoir, the next time I start the tractor, after a few minutes when the thermostat opens up, it will blow coolant out the overflow to get back down to the lower level. After that it's fine, I can run it all summer with no more blowing, and no overheating problems. So I've been operating on "if it ain't broke, don't fix it". I do wonder what happened when they pulled the engine for the clutch job that changed things.

I had a radiator off one of my tractors to replace a pump and set it outside the shop for a couple of days. A big mouse had died in the top tank from drinking the anti-freeze unknown to me at the time. After a lot of over-heat issues and finally doing a back flush I found the carcass and hair. Anti-freeze is one of the best small critter attractants there is. Kills them fast.
