What Is This On My CK30H?

I concur, it's a secondary place to add oil; that's my:2cents:

I want to say I believe it is the correct place to add oil- check your owner's manual. Putting oil in through the valve cover can cause a vapor lock type condition where the oil does not pass through to the crankcase as it does from the lower fill port, thus causing problems. I seem to remember reading about this- just can't cite where. And I don't have a CK series, so it may not apply. I'd want to know for sure before I do possible damage to my engine though. See what the manual says and report back so others aren't mislead.

I've no idea what Kioti manual says but here is the page from my Bobcat OM. Note the caution statement in left column under second picture. Usually not a problem if filling with quart bottles with some time for oil to run down while opening the next bottle, but can overfill the valve cover and put oil through the crankcase vent into the air intak manifold if dumping full gallon or more at non-stop.

There was a thread in the New Holland forum 1 or 2 years back about hydro lock and wrecking a engine when changing the oil and using the valve cover to add oil.

I have one question...If (and I'll call my dealer tomorrow), if it is potentially dangerous to add oil in the valve cover...then why would Kioti even have the cap there?

Probably because same engine block, head, and valve cover are used on earlier emission rated engines that have open crank case vent. These engines can still be made and shipped in tractors sold to other countries that don't have the same EPA specifications as in US & Canada.

I still think if you have the possibilty to destroy your engine by adding oil through the valve cover, there would be some kind of seal so you couldn't add oil there or at least a warning sticker by that cap...I'll find out tomorrow.

Thanks SSDoxie for showing exactly what I was referring to!:thumbsup:

Texas, you are thinking this through too much, or something. Call your dealer if you so choose- but what was stated in the page from the Bobcat manual is EXACTLY what I was alluding to but could not find when I stated it.
Ask yourself this- why would KIOTI/Bobcat state something as a warning in the owner's manual if it were not applicable?
Warranty and owner's manual texts state that Mfg reserves the right to make changes WITHOUT having to make them to stock/parts, etc. prior to the change. They can do whatever they want- so long as you're warned somewhere- like an owner's manual given to the consumer at purchase.
You can do whatever you choose to do- my concern is to provide accurate information to you since you asked the question originally, and especially to others who may later read this thread and possibly be misled by faulty answers.

I guarantee your dealer will tell you what we showed you about filling at the side of the injection pump.

I would venture to say since the same manufacture made both the Bob Cat and the Kioti the same information can be found in the Kioti Owners Manual. Several people have made the mistake of rapidly pouring oil into the opening on the valve cover and damaging the engine. As to why a manufacture would include the fill location on the valve cover several people have asked this question. I assume the maufacture thought maybe if someone owned a diesel engine equipped piece of equipment they would know about hydro locking from rapidly pouring oil into the valve cover fill port.

I may be over thinking this a little too much Coyote...lol, and I will be adding oil through this port on the right side of the engine going forward. I'm just perplexed as to why they would provide an oil fill location in a place where you can't add oil and be 100% sure you aren't going to damage your engine.

I know very little about all the technical aspects of diesel engines, as all my vehicles used for transportation in the past have been gasoline engines. Most people that service their own equipment are use to adding oil via the valve cover on engines, especially when it is in plain view.
