I was changed my oil today and it looked terrible. Flushed it about three times and still showing signs of water. Do these motors have a lot of blow by? When I take the cap off it will blow back in my face. The machine runs fine however. Help please

Thanks

'Blow by' won't make it show water. But a blown head gasket sure will!

The fact that you have pressure in your rad that almost blows your head off makes me think head gasket... No question!

 

[Bustem504]

yea the radiator does not seem pressurized but I am going to let it sit overnight and check again. Is that much blow by normal?

 

[canucklehead]

If everything is working properly, you should NEVER NEVER NEVER have water in your oil. If you have even a drop of water, something ( head gasket) is hooped.

Blow by is oil getting into your combustion chamber due to it getting past the rings. If youre burning oil, it's likely the rings/piston/cylinder, or leaky valve seals.

Blow by and water in your oil are not the same thing, nor do they have the same root cause.

thanks I understand they are two seperate issues. It just seems really odd they happen both at the same time. Im going to replace the rings I guess and check the headgaskets. What is the compression supposed to be in these engines.

Well I got some of the story from my little brother. He sunk my bike on the passenger side almost to the glove box. (little son of a B%%^&) He and a friend pulled the plug and blew out the water but failed to tell me any of this. I am going home and flush it a couple times with some new oil and see what happens. What else can I do to help one of the problems?

 

[canucklehead]

I've heard (and done it with a friends Grizzly) that a good way to flush out water is to drain the oil, put in a litre or so of diesel, and rock the crap out of the machine. Drain diesel and repeat two or three times. THat will really help get the water out.

It worked well for the grizzly, but can't endorse for the Rhino since I've never done it! I'm sure someone on here has a procedure that works. Google can assist too... Good luck!

Thanks for the info I will try it?

I found some stuff on a 50/50 mixture of diesel and oil has anyone else used this method. Also using sea foam. What is better?

Which cap are you referring to, if it is the oil cap, dont worry about it..............

 

[Bustem504]

yes the oil cap. really dont worry about it. Why???

thanks

 

[canucklehead]

As far as I know, the crankcase SHOULD be pressurized somewhat... I don't think that's the result of 'blow by'.

 

[willykiller]

thanks

What you are experiencing is the movement of air caused by the piston travelling up and down in its bore.............
This will cause air to be blown back and forth though the oil cap filler pipe...........
Totally normal.....................

Ok sorry used to working on my dieseltruck and that kind of blow by means something is wrong. But if it's normal on these machines thats one less problem woo hoo

It isn't blowby................
On your diesel engine, which generally has multiple cylinders, the volume of air in the engine base, (crankcase) doesnt change because one piston moving up with another piston going down in its bore will equalize the volume in the crankcase................

Thank you for the knowledge. I appreciate it.

I am still getting water in my oil. drained it 4 times with new filters also ran a 50/50 mix of oil and diesel through it. I cant figure this out

 

[RuttingRhino]

The question is how much...and is it swamp water or coolant...???

Is it getting less and less each time you flush...or is it always the same and your coolant is going away a little at a time...???

If it's coolant it has to either be a head gasket or water pump seal...

If it's residual swamp water eventually you'll get it all out...

 

[Bustem504]

The first and second time the oil looked like swamp water. I got better the next two times and I thought I got it all out. Well I took it for a little spin today and low and behold the dip stick was all white again.

The important thing is if the coolant level is depleting. There are several spots in the trans and engine in these Rhinos where water can collect, I'mk not sure how you would get it all out without dismantling the engine or turn the Rhino upside down...............:32:
