ok i have changed the water pump seals and installed new gaskets.
what could be causing this?can it be a blown head gasket?if not where should i look?

 

Your counterbalancer is separate from the engine and the aforementioned possibilities do not apply.

If your fluid is milky it is because you do not have an adequate seal somewhere in the counterbalancer.

ok let me go a lil more in detail.i put all new seals in water pump new gaskets its not been in any water at all since i did this so that cant be it.also there is no water or collant coming from weep hole.its going to counter balance and coming out overflow tube.Thor are you sure on the conter balance being separate? cause in the repair manuel it says nothing about crankcase fill up just counter balance.also my dealer said counter balance and crank case is the same lubricate.i know theres a crankcase drain but it says nothing about a fill up.so i was taking that they are lubbed with the same fluid.am i wrong on this?

 

bermbanger400,

Everything except for the counterbalance bearings is lubricated by the oil/fuel charge coming in through the carburetor. The counterbalance has it's own oil. If your coolant level is staying the same, then it probably can't be attributed to coolant getting in there. In order for coolant to get into the counterbalancer, I believe both seals on the counterbalance shaft would have to be bad, as it has one seal to keep oil in the counterbalancer, and another to keep the coolant on the impeller side of the water pump. Even then, it seems that the water would drain out the weep hole, unless the weep hole is plugged with mud or other debris. One other thing to take note on is that once water enters any place with little nooks and crannies, it may take several flushings to get rid of all the water. In 4-stroke engines that were submerged in water, and ingested water into the crankcase, it has taken me 5 consecutive oil changes to get the water out. Simply draining and refilling has never done the trick. A trick that might work would be to pull the counterbalance drain plug, and pour gas continually in the fill hole, allowing it to flush everything out of the counterbalance. Let it sit a few minutes to drip dry, and then refill with oil. Diesel or kerosene might be safer alternatives to gasoline, as they are not as flammable. If you are overfilling the counterbalance with oil (there's hatching on the bottom of the dipstick), it will overflow every time until the excess is blown out of the counterbalance housing. Let us know how it turns out.

walexa it was clean as a pin when i put it back together rode it for about 30 mins started blowing milky looking oil out the overflow just like it did before i put water pump seals in it.i understand what you are saying about the 2 seals seems weird to me too that the coolant could get past both them so easy.i think its something else.i think ill just go trade it off let someone else have the probs ive had enuff with it.

 

How much oil did you fill it with,from what I remember it is 75cc's.The last time I got water in mine it took about 5 flushes in a row.I would fill it completly full run it a few min,drain & flush again till it came out clean.Good luck.

 

I have had the same problem with mine an my friend had lost a motor cause of it we now are using slick 50 gear oil in them it sicks better to the gears an the bearings.

 

x-scrambler what was causing it?i may overfilled it some i just had to guess at amount.ill change it again and see if it still does it.

 

We never found what the problem really was we just check the oil offten. One posiblity is at the oil injection pump we have been sealing it up around every spot around the cable the cover. So that is an area to seal up really good.
