UPDATE: https://www.wolverineforums.com/forum/266-x2-x4-engine/27874-installing-oil-catch-can-x2-x4.html

UPDATE2: Guys, you really don't have to respond with the survey below. We know it's due to overfilling.

X4 owners, please chime in.

So far two of us (more have come forward) have experienced PCV oil accumulating in the intake tract to where it will collect in the clear drain check tube. Please check yours and report:

1-If your X2(new model)/X4 is exhibiting this problem
2-How many miles/hours you have on your vehicle
3-What oil brand/formula/viscosity you're running
4-What kind of running do you do, ie; high speed or regular trail use
5-Are you making sure you're checking the oil level properly, see image below
Image

6-If you reported it to the dealer and if so what did they say

Please take pictures if possible

If it's not being caused by high blow by, then possibly a baffle needs to be installed and/or a redesigned/modified airbox to allow oil to collect closer to the throttle bodies.

Me,

1-Yes
2-2700 miles
3-Mobil 1 0W40 EU formula
4-Mixed with high-speed highway runs
5-Yes, checked as per manual
6-Not to dealer yet, but to corporate

Initially noticed wetness below the intake tract:

But in the past week or so have noticed dripping from the bottom where the CVT fluid inspection tube is located, will get pictures/video soon.

Doing baffles was in lieu of installing the catch can, not in addition to it.

I checked mine with my oil change. I put a better clamp on the drain pipe too.

1-no issues so far.
2- 28hrs, 314km
3- Yammie lube 10w 40
4- Pretty tame trail riding. It's my family mobile.
5- I believe in checking it correctly.

Owner of 2019 x2.
Same problem.
Oil was dropping to the garage floor form the air intake tube.
At the lowest connection, just before the catcher tube.
Took it to the dealer who cleaned the tube and thought out the problem.
OVER FILL OF ENGINE OIL BY THE DEALER/FACTORY. (you tell me)
EASY TO DO IF LEVELS ARE FILLED AT COLD.
MUST BE BROUGHT TO OPERATING TEMP.
Here is what I have done at first service. ONLY REPLACED WITH 3.24 QUARTS. Oil level is between the the high and low mark.
NO ENGINE OIL PROBLEM NOW.
Hope this helps others.

Actually with the oil filter is 3.5qts max. I would follow the manual exactly. Dry sump systems are completely different. Your dealer is incompetent that you bought your machine from as they overfilled it. I would NEVER take it back to them again.

My dealer didn’t even have the oil on the dip stick!

I full heartedly believe that no one cares about YOUR repair more than YOU. I’ve heard more horror stories about these small engine dealer mechanics than most other vehicles. All the older guys who know what they’re doing most likely start their own shops.

Flesh Eater is absolutely correct.I also believe NO ONE DOES A BETTER MAINTENANCE SERVICE THAT YOURSELF.
My dealers as most are multi brand operation.
That tries very hard for their customers.
Infidel MT I am sorry that you so outspoken and wrong.
I DO KNOW WHAT THE MAX IS. The note is maximum. I do know about dry sump operation. Very possibly more than you.
My post was a indication to others of what I feel is a safe operation.

Add WHATEVER amount YOU want then. I'm not here to argue with you. This is directly out of the manual.

So has anyone figured out an exact measurement of oil to put back in the machine after completely draining it, as well as replacing the oil filter ?
I did my first oil change last fall and it was a pain in the a$$ . Dont have the manual handy now to reference, but I followed the procedure in it.
The dry sump thing is what threw me. I put in the 3 quarts I think it was that the manual said to, there was nothing on the dipstick. Then I recall running the engine to warm it up, which brought the level up to above the xxx marks . So I drained a little and tried again and it was still too high...
Anyways .. long story short, I remember draining and then adding back almost everything I drained to get the level right again . Then after a ride it seemed too low . I ended up adding a little again to get it in the center of the xxx on the dipstick . In the end ... I have no idea exactly how much oil I ended up putting in the machine . An exact measurement would be niece to know.
I guess it’s the dry sump system ... I’m not a fan . My rhino was drain .. put in 3 quarts and go . Didn’t even have to check the level because it took what it took, and was always the exact spot on the dipstick so long as it was fully drained and I put in the 3 quarts .
This seems like a guessing game on this dry sump . Has anyone figured out an exact amount of oil that ends up being correct after it’s warmed up and settled etc ?

SLIME GREEN CAT AND ALL,
I been trying to get a handle on this try slump.
Even my dealer admits it is trying.
The best results I found is taking a short ride and getting the motor up to normal operating temp.
The 10 minute works too after I did the short ride and wanted to double check.
THIS WHAT I FOUND TO STOP THE MOTOR OIL PROBLEM.
I put the recommended 2.64 quarts after I changed oil and filter.
Then I let it idle for 10 minutes.
Added oil up to 3.24 quarts.
I found the oil to be at a constant level between max and min.
3.49 quarts is the max per yamaha.
A lot of us had trouble with that mark.
Maybe yamaha should change the max mark.
gary (hope that helps)

It seems to me when I read the manual, you do not screw the dipstick all the way, but I may be wrong. Don't have the manual with me. People say my memory is shot. People say my memory is shot.

Correct. You insert the dipstick without screwing it in.

[That's what she said.]

I just did my second oil change. Got it up to 165 degrees before draining. Drained everything, added precisely 2.5L. Nothing on the dipstick. I got it up to temp, waited, waited, waited, nothing ever showed up on the dipstick.

I added another 3/4 qt. or so and finally got oil on the dipstick. I need to write down 3.25 qts. in my manual so I don’t do this again.

I pulled the cover off this past weekend to replace the wire clamp with a worm gear type. I was greeted with a stream of oily goo. About 1/4 cup (I'm guessing) as it went into the gravel.

Here is the input requested at the start of this thread

1- Yes 2019 X2 Model
2- 50 miles
3- Yamaha Dealer oil change
4- Regular Trail use
5- Yes, checked as per owners manual
6- Not yet

So when I went to turn my X4 Around in the driveway last week to do my CV boot I noticed that I had a small oil spot on the driveway. My first thought was, REALLY! I have 3,300 miles on my X4 and have never had a drop of anything on the driveway. I decided just continue on the CV boot. One thing at a time. Plus I had planned on doing my 3,000 mile service in another week on my next days off so figured I would look into it then. So while doing my service yesterday I remembered this thread and popped the drain cap off and had probably the amount of oil that Massive had in that picture of the bottle pour out onto the driveway. Crazy that it just barely started dripping and showed me this issue. Plus I changed my secondary air filter as part of my service and the original filter had no oil on the backside of it. I also shoved a clean white rag as far down the intake tube as I could reach and it came out clean. At my 1,500 mile oil change, which was the first one I did myself on the X4, I remembered adding the 3.49 quarts that it says in the manual and it being low on the dipstick so I added more to bring it up to the MAX level on the dipstick. Not this time. I am sticking with the oil quantity that it says in the manual and not adding extra. After reading this thread it sounds like overfilling is the cause of this so Ill live with the lower oil level and see if the issue happens again. Crazy though that there could be that much oil in the intake tube and it not affect the way it ran at all.

Right on Wolvy 3.49 qts with oil filter max. Anyone fills it to 4qts it’s overfilled and puking out the intake drain. These dealerships need to get a clue.

if you check the oil when it is cold it will not show on the stick. if you run for a few minutes it might hit the stick a little bit. run it for 10 miles and then it will show full.
it seems counterintuitive but that's the way it is. I don't know where it hides, but unless you believe you have a leak do not check it until the engine is completely warmed up.

So I just noticed a small nickel size oil drop on my garage floor tonight. I went and inspected where it was coming from and it’s the intake tube rubber coupling. I pulled the drain plug and got about a 1/2 cup out of it.

This is after I just changed the oil about a hundred miles ago. I DID NOT OVERFILL THE OIL. I dumped the oil and filter and refilled with 3.4 quarts of oil. I don’t care what the dipstick shows because it isn’t reliable anyway. At least not for about 50 miles or so. For reference this was after my 3rd oil change and this has not previously happened before. I’ve done nothing different.

Are their any other explanations for this? Should I be concerned?

My other issue is the color of the oil on the towel. Kinda dirty for 100 miles. This was from the oil that had pooled directly in the plug nipple. I’m thinking it might just be a collection of what was left in the tube from manufacturing? Or the fact that the nipple cover isn’t 100% sealed from Mother Earth? The oil that came out of the drain nipple was clean as was the drain nipple itself as you can see. I’d love to get access to the rear half of the intake tube nearest the engine too see if their is any dust in there getting by. The front half that I can inspect is whistle clean. Also, I have done massive’s test of the intake system and it passes, stalled the engine out. (Although I admit it takes several seconds to stall)

Do yo do any high speed running?

Not really. I may run it up to 40 MPH if by myself for like a mile maybe once per 500 miles. Other than that it spends most of its life in the 20’s and 30’s. Is it possible that a person doesn’t get all the oil out on the oil change and thus putting back in 3.4 quarts would be overfilling it? I drain the oil after a ride so its well warmed up. I am aware of the 2 engine drain bolts and sump drain bolt. Hell i even let it drain for like 2 hours while i’m fiddling with other stuff in the garage.

I have almost 2000miles on my x4 and have always gotten some oil in the intake if I fill it to the full mark, seems to like being on the lower end of the dipstick and stay there, I have never had to add any oil between changes. Any way I got tired of the drip from the intake tube. As tightening the clamps didnt help muich I decided to pull intake out and seal it up better. It turns out that it comes out of the machine with out much drama. I removed the air filter box and was able to pull the entire assembly out of the front. I took it apart cleaned it up and then siliconed the coupling both inside and out. If you do this dont tighten the clamps up fully until the silicone cures, otherwise the clamps just distort the rubber and make it try to slide off the tubes. I will see if this fixes my slight drip coming from the tube as its parked. I may add a catch can later but for now I hope this will keep it from making a mess. I replaced the clamp on the little cap a long time ago, I happend to have an automotive sqeeze type clamp from a heater hose that fit perfectly.

Are you sure they're burning oil? How many miles on each? Have you done my intake test to make sure you have no air leaks?
