CK series owners- clarify where you fill your engine oil: location on engine

[TJP89]

I'll look for the side port. If I have one I'll use it, probably easier than the one on top anyway. Might have to take the loader off though. 200hrs is coming up for me anyway.

You should be able to leave the loader on. What I sometimes do is remove the implement from the loader and put the loader up high and lock the FEL lever and use something to hold it in place like a stone wall or 2 x 6 or similar, then take off the side plate under the hood near the IP. This makes access to the area a snap.
Give us a pic of your engine's right side with the side cover off, if you can to show what your set-up is.

Thanks,

Thanks, I have to put the snow blade on tonight, so I'll be messing with the tractor and try to remember to take some pics.

Talking with the diesel engine guys at work they are asking me how does the oil get into the combustion chamber when filling valve cover to quickly ? I have put 3 hrs on the engine since i overfilled it. It still blows a light blue smoke and clears up when engine gets to temp, but at idle you can hear the engine miss slightly and see the smoke stop for a brief second. There is also a ticking sound like the tappets clicking.But the tractor runs fine at power with no notable loss of power.

Older CK/DK models did not have the orange oil cap near the IP. Different models converted to the new configuration (red cap on side by IP and stop solenoid on front) at vaious times between 2005 and 2007, I think. You can look at one of the online parts manuals to get the exact serial number when each model went to the new configuration. If you have the side fill port you should use it. If you only have the fill port on top of the valve cover, add oil slowly. If you fill too fast at the the valve cover (flooding the valve cover with oil) it is possible to hydro-lock the engine if oil gets into the intake manifold through the crankcase breather passage. That would be a bad thing.

Took a look at mine this weekend. Sure enough the orange cap (right in front of the throttle assembly), seems to be an oil fill port. The side panel has to come off, and the loader is in the way, but I'll likely put the oil there in another 20 hours or so. Sorry, but no pics. With the hydro oil on the H needing changed, the front axle fluid on the Kioti needing filled, and a foot of snow, I was a little busy this weekend, and never got the camera out.

The engine has a breath/vent so it doesn't built up pressure in the crankcase.
These engines breather tubes are in the valve cover.
On the older engines the breather tube simply ran from the valve cover down the side of the engine and vented into the atmosphere.
On the newer engines for pollution control reasons the crankcase breather tube goes from the valve cover to the intake manifold so the vapors can be re burned and sent out the exhaust.
If you fill oil through the valve cover a lot faster than the oil can drain through the drain holes in the head to the oil pan it can buildup high enough in the valve cover to get down the breather tube into the intake which is not good.

I had a partial hydro lok after i had changed the oil ( did not know about pouring to fast issues ). The engine started the second time and every time after ok. The tractor runs ok and makes power ok. Thinking maybe a valve is damaged to cause it to still smoke? It smokes at low rpm but clears up where taken up to power ( 2000 rpm ). Since i don't have the time to really dig into to it i will be putting it on the trailer for a trip to the dealer. Bums me out about the 'pouring to fast' issue !!! Only have 250 hrs on the tractor !

If Kioti puts the breather tube where oil can get down it by poring to fast in the valve cover there should be a warning in the owners manual so people know IMO.

Does anyone have a picture of the breather tube and valve cover on a CK model ??
I'd like to see how its run.

Not a picture, but a parts diagram. You can see how breather tube comes off of the side of valve cover, near the top. Also, it is only a few inches to the port/nipple on the intake manifold. The problem some have had with oil infiltrating the manifold during an oil change, is easily solved by using a funnel that won't flow as fast as the oil will come out of bottle.

The real problem with this design, is what the blowby gases (and their contents), will do to your intake valves......but I've already covered that in my earlier post.

Seems the biggest obstacle to oil flow from the head to the pan is part #7, what appears to be a baffle.
And yes, using a funnel would slow the flow. If there's an alternative fill location on an engine, I'd tend to want to use it to prevent mishaps. YMMV.
