Water in engine oil

**evoetr** · 30th July 2009, 23:17

I have water in my engine oil!

Bugger! Anyways anyone know of anything good to flush it out with ? i gather im not going to get it all out for like 3 or so oil changes...

I remember wiping out in a big clay puddle in mungatuks. But it only covered buttom half of the engine so trying to work out where water got in to the engine on my 03 yzf450... any ideas ?

Also any easy way to rule out that the water was from the puddle not my coolant apart from the radiator level? Because the level is down but not by much and i haven't toped it up in ages....

Cheers

Your cooling system can be pressure tested. If it holds pressure, it's probably not from there.

did it fall on the left hand side ...might have gone up the engine breather pipe ? just keep changing the oil till theres no more water,, is there water still in your radiators ?? oh if the levels down you may want to give it a pressure test just to be on the safe side ... have you drained the oil ?? how much water was there??

use a engine flush

If you stalled with the oil breather in water that would do it.

I'd go for diesel ( twice )
get some cheapish oil & filters,
- fill up with oil run on idle for 5 minutes, drop the hot oil
- Put a new filter in, fill up with cheap oil again & run for another 5 minutes, drop the oil hot.
- New filter, good oil, go ride, after that ride, new oil, new filter, then back to normal.

Never done it of course

Ummm it fell to the right and stalled i caught it before the whole bike went in the drink, then tried kicking it over with the bottom part of the engine in the water (Now that i think about it that was a dumb idea) but i thought as the water wasn't near the air box or plug it would be safe.... It wouldn't kick over after like 15 kicks or so pulled it out gave it like another 20 or so kicks and got started...

Yep still water in the radiator only gone down a little, i thought with the 03 yzf450 would always use a bit of water from (Not a big amount just small amount) because it will expand when hot and go out the over flow pipe to the ground?

Apparantly on the 2009 design bikes (And not sure what other years) they actually have a coolant overflow bottle to catch it.

Cheers all for your help

How much water was in the engine ? or Radiator ?

Radiator not missing much at all its down about 2-3 cm from the lid but i haven't checked the level for a couple of rides

In the engine, well the water and oil have combined to make this really cool white gooey stuff, looks like it will be a nitemare to get it all out. Esp with the oil running through the frame on this bike

All good suggestions, but how about this.

Remove the crankcase breather from the air box, and run the engine until it's above normal operating temperature....... the water will evaporate through the breather and in to the atmosphere (rather than the vapor going into the air box, then, when cool, running back into the crankcase as would normally be the case)

Of course DO NOT RIDE ANY WHERE NEAR WATER when running with no breather.....that could end in tears!

Ahh the oil breather in the water... ? Ok so it would suck it up or something while kicking over ?

Was thinking about starting it for like 5mins with some car oil same grade Castrol edge syntec 10 30 with no oil filter. Then drain as much as i can out and chuck a oil filter in and some new oil and go for a ride then change it again straight after...

Hmm i really need to get a washable oil filter me thinks...

So diesel is allgud ?

Not to sure if it'll suck in when you kick start, certainly stalling can do it.

I used something like Edge Syntec, can't remember exactly, I reckon you need two washes ( diesel & oil ), that foamy stuff you end up with in the motor is not so easy to get out, I filled it with diesel to the top, put the cap on & flipped it side to side a bit to try & run the diesel around.

Diesel is easier on rubber & bearings, was what I got told.

I don't think so. This will homogenise the water with the engine oil, into a nice creamy golden mess - it will be only useful for spreading on your arse. The water will not evaporate at all.

But hey look at my avatar, do I look like a scientist?

yeah man. don't "run it to evaporate the water" that's rediculpus. I have siezed the cams into the head of my bike running it on "water paste oil" and I did it in the mungotuks too lol. Bad idea. Mine sucked water through the breather when i stalled in a puddle too.

When you've flushed it with oil and got it sorted re route your breather into the air box and put a little filter, soaked in foam filter oil, on the end. You can get little pod filters from supercheap... the boy racers put em on valve cover breathers
