I know this has likely been discussed but most of what I have found in on the older motors. I am getting a decent amount of coolant in my oil. No oil in the coolant and no leaks from the weep hole. Gasket on side cover looks good.

It doesnt seem to be pressuring up the cooling system either.

Other than head gasket is there anywhere else for water to get into the 70 degree motors. Do they still have orings at the bottom of the cylinder?

I bought it used so no history on it. It is a low hour machine.
 
Have you been running for a long distance? Could be even some condensation( nothing to worry about in this case)

Gaskets, seals, and chambers are the only things that separate the the two. Water and oil

head gasket failure even duo to poor workmanship could be the cause

If it's a new bike to you I would have it check
 
If the side cover gasket is good and nothing from the weep hole there are only two places. Top or cylinder gasket, see pics.

Unless you have dirt in your weep hole so the water cant get out. Or if the vent hose has jumped off and you are driving through water now and then?
 
I can pretty much be positive its coolant. I had a red colored collant and the oil looks like a strawberry milkshake. I rode maybe 5 hours. I had a good amount of oil in the air cleaer housing fom the crankcase vent, enough that the engine was sucking it in. Makes me think compression pressure in the case but it isnt burning oil or water. Could have been due to water/oil foam building up in valve cover maybe.

I was hoping the weephole was plugged, but it appears to be fine, can push a plastic brakecleen straw in it an inch or two.

I suppose i should slap a set of rings on it while i am in there. Do these use ktm parts are is there a good plase in the US to get parts.

Can i pull the head and cylinder in the frame on these.

Thank you for the pictures and the help.

I have wanted one of these 70 degree bikes for many years. I hope it doesnt bike me in the ***.
 
Ok then you have good indication that coolant is going into the crankcase/valve cover.... Also the oil in the airbox is not normal and is probably due to pressure from the cooling system.

Maybe it's possible to remove the cylinder with the engine in the frame. Personally I would remove the engine because by the time you can try to remove the cylinder most of the parts are gone anyway. Welcome to the autocad generation.... Not much extra space. The upside to take away the engine is, apart from cleaner and nicer work environment, is that you can have a look at the swing bearings and electrical loom.

If you remove radiators, throttle body, header you might get away with it.
 
It's most likely the impeller shaft seal

Most likely, it's the shaft seal behind the impeller.
Especially if you're seeing milkshake out the crankcase/valve cover breather.
 
Do not pull the cylinder until you've replaced the seal for the impeller shaft.

I'm just went through this with a KTM. Same situation. There's just the one seal separating the coolant from the crankcase. If that seal is compromised, the coooant, when hot = pressurized, will leak both coolant and pressure into the crank and out the breather.
 
The 570 has 2 seals in the impeller shaft with a weep hole between. As Dirtrulz has checked that the weep hole is clean he should see water coming out of there if the seal was leaking. Sadly it's not.

I dare do not take responsibility for my suggestion because I don't want him to pull the cylinder if there's no need. But I feel I have to share what I believe and I can't see any other way the water will go into the oil. If anyone can come with other ideas please speak up.

With nothing from the weephole i fear the worst. Am i stuck going to ktm for parts or are better gaskets available elsewhere.

Thanks for the help.
 
How much coolant are you loosing would be my first question? If it is minimal than the impeller seal, If it is allot then the head gasket leaking into the chain valley or somewhere in this vicinity. After you run the bike, let it sit so the oil and coolant separate, then drain the oil and check to see how much coolant comes out first. It takes a couple days to separate from milkshake to coolant and oil.
 
Crankcase was overfull at least a half quart. I dont see how its the waterpump if the weephole is dry. I will get to it sometime this summer. May just break out the old ktm 450 and ride it. Will hate going to a carb now.
 
Finally getting around to fixing this thing. Is this Athena P400270620037 the correct kit, it only lists the 450 but says it works on the ktm 530 so it should work for the 570 correct. Or should i go with the ebay gopper head gasket and stock base gasket.

Or would the Cometic C3244-EST kit be better.

Would like this to be the only time i have to do this.

How many hours on your bike? If it has enough, I'd be fitting a piston kit. Make sure the gasket set matches the bore size. No Oring at the base of these.

You should be able to do the job in frame. I did my 450 this way. Replace piston on rod then fit barrel, not piston to barrel then rod. Use a wide cable/zip tie as a ring compressor.

The reason you were getting oil in the airbox is because the coolant was raising the oil level. When that happens it pressurerises into the airbox.

Make sure you lock the crank by the bolt bellow left of the filler plug and the camchain dots align.
 
450 and 530 have the same bore size. 570 is bigger
 
I am having a hard time finding a head kit that lists the 570. Is a dealer the only way to get them now? I may try calling athena direct.

The bike has very low hours but spent lots of time sitting.
