First of, im new.
I am Patrik from Austria. ( sorry for my english )

My problem

First water ran out of the little hole, than i replaced
the 2 seals,the bearing and the shaft of the waterpump.

Now nothing comes out of the hole, but after 45 min riding the oil looks like a milkshake again.

Can somebody tell me all the places, spots in the engine where water an Gearoil can be mixing tougether.

engineoil still looks like new.

My bike 05 crf 450 daverio formula Supermoto.

Basically where you checked which was the Water Pump Seal and Shaft , AND the head gasket

If the oil WAS milky , then you might try getting some cheap oil and flushing the engine a few times , to see if it clears up

Put in the oil , start the bike , and let it run for a minute or so (no more than a couple minutes) , then shut it off and drain the oil , repeat till it clears up , if it does not clear up , then i would guess you blew the head gasket if the engine got real hot when the coolant leaked out

[Patrik]

Thanks for your answer.

I will try this
But if the headgasket is blown up, the water would be in the engineoil ?
Or am i wrong

[Aussiecrf230]

That is correct Patrik.

If there is a milkshake in the gear oil I can only think of three reasons.
1. Creek crossing has let water in via a breather hose
2. Waterpump seal failure (or installed wrong way around)
3. Washing with pressure cleaner has forced water in

Sorry i misunderstood your accent , i was thinking you meant Engine side .... my bad .... then yes , as Aussiecrf230 said , it has to be in the water pump somewhere

I would think a Steam Cleaner rather than just a pressure washer would make the oil milky , because i pressure wash my bikes after every ride with my 2750 psi pressure washer , and have never had milky oil , and it would dissipate if it were just condensation , the moisture has to be a large amount to keep the oil milky so you need to be looking for a way for the water to enter the tranny , which will either be a opening somewhere with a bad O-Ring or gasket , or the Water Pump seal

Also if engine oil and tranny oil were mixing, then either your engine side or tranny side would be overfull and the other would be low

[Patrik]

Yes my accent is bad.

I never use a pressure washer, im afraid of dirt that's why I drive Motard

It is so hard to explain something in another language, sorry
And the little hole, you call it wheep hole right,
Nothing comes out, it is dry at any temperature
And that means to me the first seal on the outside has too be ok

So how the hell is the wheephole dry an my
Oil so mixed

[JimDirt]

Unless you put one seal in backwards , one seal goes in normally , the other is what would be considered backwards , if you have it reversed , it will allow water into the oil , one is a oil seal , the other is a water seal , as long as you followed the manual then the seal should be in right

Its a matter of water can only get in via the water pump shaft , so i would guess it has to be there , maybe during installation one of the springs that hold the seal tight to the shaft popped off , maybe reversed seal , maybe the lip of the seal got damaged , but i would guess your issue would be in the pump somewhere

And i was joking about your accent , i just read it fast and not thoroughly , and just saw "after 45 min riding the oil looked like a milkshake again" and figured head gasket

My bad , not yours !

[Patrik]

Thanks for quick response.

I will order the new seals tomorrow and tell
you of my problem is solved.

[Patrik]

New seals in it ! still the same problem

[Aussiecrf230]

The casting doesn't have a pin hole letting water in?

Can you post some pictures of your seal setup and waterpump shaft.

Without water in your radiator pressure test the cooling system and see if you can hear an air leak.

[Patrik]

Ok, i will Take a picture tomorrow

The casting looks ok

behind the waterpump, there is the hole wehre the water flushes under pressure towards the cylinder, there is this Little steelring and sealring, i also changenged this seal
Is there a possibility that the water mixes behind that hole with the oil ?

I wanne see the whole way through the engine, and i cant find an exploded view.
