Allis is Making Oil

[Wingnut]

After Harping on the Allis 65th Birthday

She started to make oil when I picked up the kid at the Bus Stop!

Everything is running fine; but she making oil and a lot of it.

Yes we had a freeze here the last 2 nights but I always have antifreeze in my radators.

Making Oil --- When water from cooling system contaminates the motor oil.
Basically; the motor oil has turned into milky looking substance the coolant is mixing with the motor oil.

There are several factors that can cause this:

Crack Block :fing20:
Crack Head :fing20:
Blown Head Gasket: :fing20:
Cylinder O-ring is shot :fing20:


There were 5 planned activities I was going to do the Allis this spring.
Replace the front and Rear Oil Seal (Required pulling the Engine)
Fixing the leak on the Bull Gear (make and replace a gasket)
Complete the install of the 3-Point Hitch
Remove the Dents and Sand/Repaint

Hate to hear that BigOrangeDan is not going to like that :banghead3 Maybe just blew a head gasket.

[Wingnut]

I starting to think it is something with the Head or Head Gasket.

I have oil in the coolant some fresh oil and a lot of gunk that was antifreeze, oil, and a water mixture. This rules out the Bad O-ring on the cylinder sleeve(s). It really to push oil through O-ring on the cylinder sleeve with pressured water pressing down. There also that 2" air-gap cleeve and the oil sump, but if somebody was using the Tractor upside-down........

The engine has never smoked and knocks. There was plenty of antifreeze for the 29º temps the last 2 nights.

So I am looking at the head or head gasket as the problem.

[Wingnut]

The picture above were taken with the engine idling.
There is a new oil resdue between the Block and the Head.
Oil, water, or both is not getting into the cylinder, the engine sound and acts normal.

[sonny]

gasket can be leaking , but dont sound "blown" or motor would miss on one or more cyls. Could be on backside of head bolts and getting into the pushrod holes,then into the oil pan, oil passage under pressure could let oil/water mix and go both directions> thanks; sonny

[mark777]

Wingnut,

Is there any indication of the smallest exhaust bubbles in the radiator?? I was thinking a small crack between intake & exhaust seats can be enough to contaminate your coolant but not the crankcase. Otherwise it appears to be a headgasket leak between pressurized oil galley and water jacket.....hopefully.

Good luck,
Mark

[BigAllis]

Wing srry hear yer bus has a prob maybe its just head gasket get ya new one n put on n see if thts yer prob hopefully thts all is wat snds like

[Ingersoll444]

You hate when this stuff happands!!!

Well lets hope its just a gasket. Defently sounds like a gasket or a cracked head to me though.

[Wingnut]

That is the way life is: When you own a tractor you take the good with the bad. Its looking like the top part of the engine most likely a gasket, These old bolts and stuff heck the head could have worked itself loose.

[BigorangeDan]

you broke my tractor!!!!!!!fix it! fix it! fix it! fix it! now!!!

orange should rule!!!!!! but you broke it!!!!!! fix it !!! dont make me come up-there to fix it!!

[Wingnut]

you broke my tractor!!!!!!!fix it! fix it! fix it! fix it! now!!!

orange should rule!!!!!! but you broke it!!!!!! fix it !!! dont make me come up-there to fix it!!

:imnotlist: The 2 bolts on the at the No 4 cylinder were loose, I am flushing everything now!!!!

Remember How you use to like to be Flush? "Flush me Wingnut Flush me" You really like being flush when I worked for the MI.... :fing20: can't talk about that.

[Wingnut]

A lot of interesting were found when when I pulled the valve cover.

I looked in to the valve cover and found oily foamy mess!!!!!!!!


Now look at the Head: See those pretty clean shiney silver Core Plugs on top of the head. Unfortanately I cleaned them off before grabbing the camera to take a few snap shots. The filled to the top with about 90%+ water.

The Foaming in the valve cover would be caused my steam or a jet of water. There was no foam on the rocker arm assembly, valve springs, pulls rods.

So I am going to fill the tractor up with used oil that I drained from the Mahindra to day and refill the Radator with water and dove dishwashing liquid.

The dishwashing soap with cause bubble to be easily to be seen and aid in flushing the oil out of the engine and radator.

[Byron R]

Wingnut..This might sound stupid but does it have a water pump or is it thermal...? Good Idea on the dawn to flush oil from cooling system.. :fing32: ..Br, :trink39:

[Wingnut]

Byron, it has a water pump and flush this engine out.

All my testing is inconclusive so I am going to pull the Head tomorrow after I take my to the airport.

Since I have the tins off and the the fuilds drained I am going to replace the front oil seal. I might possible replace rear oil seal too.

This is what it all pointing to.
More picture and more fun!!!!!!!

[LPBOLENS]

Wing,

If you don't have one, see if you can borrow a "Cooling System Pressure Tester". If you have never seen one, it is a small hand air pump with a hose, a pressure gauge, and an adaptor to fit the radiator fill neck. The one I have is a Balkamp product that I think I bought at a NAPA store, and is a holdover from when I fixed cars for a living.

Refill the cooling system with water, then add a very small amount of dish soap, or bright food coloring. Attach the pressure tester in place of the radiator cap, and (hand) pump up to normal operating pressure. Watch for bubbles, listen for hissing, look for colors, etc. This might be easier now that you have the valve cover off. If you still cannot tell where it is leaking, then pull the head. :goodl:

[Wingnut]

Thanks LOBOLEN

I forgot about that I have on old "Hasting" one that I totally forgot about it. The last time I use it was in 1978.

[Wingnut]

I refilled the radator and water drop started falling out of the oild drain plug(about 10 a minute).
I can't tell if it is coming from the outside of the cylinder sleeve or the inside of the sleeve.
Either way I need to pull the head to see the damage.

[Wingnut]

I left the water in the engine and I pulled the of course water went everywhere.
So in a couple of house the motor should be dry of all extaneous water droplets.

If there water leaking from the No 2 sleeve. I have not clean off the gasket material that stuck to head and block to visually see any cracks.


Picture to come need to set up the Mahindra as a school bus!!!!

[LPBOLENS]

Wing, sorry to hear that the diagnosis doesn't look that good. Hope the damage isn't too bad. Take a look at the bearings; we all know they were not designed to run in water. Are they babbit or insert? I'm not familiar with the specifics of your Allis engine. :goodl:

:1221: Doug

[Wingnut]

It still has the same water drip so I am going to pull the engine; geez I wish I had a gas tank for the TO-30 right now!

Is it a bad block or a bad O-ring that is the question!!!!

[Wingnut]

It looks like I am going to have to remove 1 sleeve, but I need to inspect the block tomorrow.

I was hoping to start a pole barn this week.


So I started to remove the engine, will have it done before noon tomorrow.

I should have my parts list down. The bad but good news is that it is suppose to rain the next four days.

I was planning on shipping and REO up to RI this week :fing20:

[Glad2bHere]

I am no expert, but if your not fouling plugs or losing compression, I have to think it's a simple water jacket crack. I have had them relined on old engines. Or maybe, if your lucky the haed gasket failed at the jacket. Either way, I feel for you. let us know the outcome. And good luck.

[Wingnut]

At least this tractor is an easy one to work on.

If I get the parts I need tomorrow and find no problems with the block I could have it running Friday weather holds up.


My work area is limited to the open air and back of a tool truck!

I already ruled out the head gasket leaking water, it has wet sleeves and I can see water weeping out of Number 2 cylinder (probably during the last overhaul one of the O-ring got knick or twisted).

[Wingnut]

The Mahindra justs doesn't have the graceful line of the Allis when picking up kids a the bus stop.

[Wingnut]

Will things appear to be better.

I have cleaned off the head and it look to be in great shape.

Today the block was total dry. I filled the water again to verify a leak around the sleeves. I don't have the consistent drip I had yesterday, I don't have a drip today at all. It could have been block was still wet and water was wicking down.

The front oil seal appears to be working right; the oil leak in the front of the engine looks to be leaking at the timing gear cover.

[glenn27]

Wingnut---Sorry you are outside, but at least you have hard pavement to work on, and the weather there is decent......

My luck used to be when I worked in the yard (BYM) was either snowing, cold or raining so hard you'd have to help Noah build the ark...

Oh, how much is the "bus ride" to the corner???? DBernie and myself might have to come out to pick up the REO, and drink all your beer :trink39: ...figured "WE" might as well see the sights!!!.. ......... And drink more beer!!

Ah-life is good!
C-Ya!

do ya think the state of TEXAS could handle us both? :trink39:

ROF ROF

[Wingnut]

Okay here is the Status:

1. Bernie Goes to Texas? That is a dangerous situation; for the Chicken Fried Steak, Jerk Ribs, BBQ Brisket, Coupland Catfish, The Texas 7 lbs Porterhouse Steak, ETC. ETC. His wife would want to send Mower down here, cuz he will want to stay!!!!

2. After inspecting everything the sleeves were not leaking water, but there was a rust channel going from the water jacket to and high pressure oil line to feed the rocker arms. And a rust trail went into the pull rod opening.
So that make oil in the crankcase and oil in the radator.

3. Leaks, Leaks, Leaks, Head Gasket, oil pan, pin hole in radator, plent of small stuff to fix. The bell housing is covered with oil, more cleaning and inspecting.

[Wingnut]

So tomorrow new gaskets, fan belt, and paint!!!!

It should be cold and rainey

[Wingnut]

More of me splitting the tractor.

[Wingnut]

What a surprise when I went to take off the pressure plate and Flywheel.

Half of the bolts holding the pressure plate were angle grinded to make a screw driver slot.

[Wingnut]

The rear engine oil seal is out and I have a lot of cleaning to do tomorrow!!!


The engine looks good no cracks in the block!!!!

Tomorrow clean and reassemble

[Wingnut]

How 'bout some picture of it
