When they let me know what they find I'll be sure and let y'all know on here.
they called me back today. Let me see if i can explain this clearly if not one that is more familiar with this can chime in and make what I'm about to say more clear. They said there was a vent line pinched under the gas tank that wasn't supposed to be pinched. Said it came from the factory like that. This vent line comes from the water pump, he spoke about the water pump having a seal that separates oil and coolant obviously. Basically he said that since the vent line off the water pump was pinched it was pressuring up inside causing it to push coolant into the motor instead of out the vent line... He spoke about weep holes in the seals.. All this was over the phone which made it hard to understand. But the culprit he said, again, was the pinched vent hose and it was causing me to lose coolant into the motor. Which i did find milky oil on my dipstick.. he said they flushed the engine out.. and noted it on the warranty claim in case it causes me problems down the road. i would rather have a new engine but that aint happening... maybe it won't cause me any problems. maybe it will. may be time to purchase the extended warranty. how much is that $1200? haha Sorry if this is unclear, someone that is more familiar with what is going on maybe one of yall can make it make more sense and articulate exactly how the hose being pinched can cause that because that is where i got lost a little. i need more explantation which i will be asking for when i go up there. id like to see it that'd make it more understandable.
Well, I am happy and sad at the same time here. I am happy that the problem was found, sad that it wasn't resolved properly. Coolant in an engine means rebuild time, I don't care who you are or what you say you will never convince me that ZERO damage was done to an engine with coolant contamination. Period. As to how much damage was done, that can't be known with certainty unless the engine is torn down. You could have minimal damage, and a cleaning and flushing of the engine will prevent future damage, or you may already have significant damage that cannot be reversed. Now, on the plus side, it is documented, and when your engine fails prematurely, and it will, you will have recourse. have you noticed it burning any oil? At the very least they need to do a dry and wet compression check to make sure the rings haven't worn significantly. Here is a link with some information as to what happens when coolant gets in your oil.The told me up there at the dealer that yamaha dont have crate motors to put into their machines... just parts of motors... i was like get all the parts of motors and put it together make me one new motor and stick it in my buggy bruh.... dont look like thats happening.
thank you that helps. It never seemed to be losing any oil i was checking it regularly. and whats strange is that i didn't notice the milky looking oil till here lately, like in the past week. they know I'm pissed upset and all that but they are taking care of this their way. and I'm getting a contract or documentation or something saying if this brand new motor craps out early bc of this they are gonna give me another on for FREE. thanks ford truck man for the explanation this helps.Well, I am happy and sad at the same time here.

As to the cause of the problem, you asked for a more clear explanation, I will give it a shot. Basically, the water pump is driven off the engine, and as such has a shaft with a seal around it that creates a pathway between the crank case and the water pump housing. The only thing block this path is the seal. The seal will protect against static pressures, doing it's job of separating oil and coolant, but if one side of the seal becomes pressurized, the pressure will try to equalize, and force itself to the other side of the seal. So if the water pump side becomes pressurized, the coolant will force it's way past the seal to relive the pressure until it is equal to the crankcase pressure. Pinching the vent line on the water pump prevents the internal pressure from equalizing with atmosphere. As the temperature changes in the pump, the pressure changes, if it cannot vent to atmosphere, it will build pressure. I will try to find an illustration somewhere. Hope this helps.
Great question. I will definitely check to see where mine is routed when I get a chance.The thing I don't understand stand about this if that vent line is so critical, which it definitely sounds like, why is it not a hard line?
preciate the input I def will keep a eye on any leaks when I get it back. the more input I get the more I can be looking for on the bike when I get it back. this is a bit of a tricky one. we will see if they can get it fixed up right with the new seals and what not.. hopefully so I need the thing running its the middle of deer season and all where im at.I have an "opinion"
I don't think this vent line would cause anything
As mentioned the same shaft that turns the oil pump turns the water pump
on the engine side there is a oil seal to keep oil in then there is a small space then there is the water pump seal. In the space between there is hole that the line is attached to
I say it is a drain line not vent. So if the oil seal fails, the oil runs out the tube, if the water seal fails it runs out the tube. This lets you know you have a problem with either seal without it going into the other. I do not believe there would be any pressure built up in anything, if pressure was built up it would push air into either the water or oil
Now if the tube is stopped up or bent in your case and the water seal fails then it has no where to go but past the oil seal. The seals have wipers on them that hold the oil back from going out but anything could pass rather easy going in.
So I would say keep this on concrete and look for coolant on the ground now coming out the seal on the water pump and now out your drain line
As far as the engine, well yes we want a new engine or new parts. But from their prospective, nothing wrong with it and until something is, nothing to fix.
They are also right on crate engines, just parts. I doubt anything is hurt but I would change the oil several times

YES is Yamaha Extended Service. It is sold and backed by yamaha. Not an aftermarket deal.They did say over the phone that the GM wanted to talk with me about negotiating a price reduction on a warranty... I attempted to get a concrete answer on that issue you mentioned above about how long they will support me on any work this motor may need in the future, didn't really get one yet. But, they may use the warranty for that. They did say that any Yamaha dealer I got to anywhere in the country will be able to pull up the info about my bike if I bring it in with problems anywhere and they will be able to see that I had this happen and that it wasn't my fault and that it happened under warranty.... said all the details will be there so.... What exactly is a YES warranty???
This is excellent information Todd, I obviously misunderstood the location of this "vent" line. This is what I always saw as a weep hole on an automobile engine's waterpump, I didn't realize this was the same thing Chief was talking about. Thank you for correcting me.I have an "opinion"

Okay can you tell me what you think really happened then if the drain line didn't pressure up and cause this. What do you think it could have happened here? ThanksI have an "opinion"
