New Holland TC33DA hydro w/supersteer
I would like to change the engine oil in my TC33DA with a Shibaura N843 3 cylinder diesel engine.

I've read that when adding the new oil, it should be added slowly to avoid engine damage. Apparently if added to quickly, the oil can find its way into the intake manifold.

So, this makes me a bit worried. About how slow do I need to add the oil? How fast is "too fast"?

I have not had an issue but I do pour slowly about a quart poured over say a minute.

Subscribed, because I've never heard of such a thing - which positively isn't to say it isn't! that's why I'm following!

Is this particular to this engine, or is it supposedly an all-engines type of thing?

Is there a breather tube that goes from the valve cover to intake? If yes then it might be possible to get oil into intake if it is lower than valve cover fill point.

Someone has given you some bad info or some "genius" on the internet is peddling garbage. When you are adding oil to the engine it is stopped so you get an accurate reading on the dip stick. Any crank case vent, even if attached to the valve cover, would not allow oil, that you are pouring into the valve cover or any other fill point to vent because the pressure relief, built into the PCV valve is well above the weight of pouring a quart or a gallon of oil into the fill point.

The TC series is affected by pouring oil into the engine to fast see this thread for the information and service bulletins on it.

Dieselscout80,
Thanks for link. I now will NEVER consider buying a New Holland product now that I can see the lack of thoughtful engineering design they put into making their products. In your link there is a post #3 and pic labeled ref 8 that supposedly indicates the connecting rod came into contact with the cylinder wall skirt at least once and possibly more. This would most likely be due to bent connecting rod due to hydro lock of the piston. If the internal crank case vent is that poorly designed then I would be looking for the recall and a new engine. If no recall then sell that tractor as it begs what other half assed designs are included on that machine.

What happens if the oil return passages become constricted or blocked? Same outcome as pouring oil in to fast. A big bill and a dead machine ALL due to sloppy design.

Wow, what a read! I would never guessed that pouring oil in too fast could cause a catastrophic problem.

yes pour slowly like in the video

Excerpts/photos attached from the Shibaura engine manual.

So, it looks like the issue may be for other Shibaura engines, not specifically the N843 that my TC33DA has?

Thanks to @dieselscout80 for sharing his experience with pouring in a quart over about 1 minute. This is the type of data/guidance I'm looking for.

They sold tons of these TC series machines with the japanese engine. And I bet there are still tons running around every day. My machine has 3100hrs with no major issues and I didnt even know about this until a few weeks ago.

I really love my TC45DA the only thing wrong with it is it needs another 10 more HP.

Remember they are all good when running, they all breakdown and all of them suck when broken down.

Have a TC34DA. They changed the oil fill location on the later model TC series. Still had the upper oil fill location but they added a lower fill toward the rear of block. Actually heard of a guy that hyro-locked his TC29 from filling oil to quickly and then starting it

They did a fix with later models (don't know the year). I made a Pour Oil Slowly label and put near the filler cap.

I never had a problem with my 1999 TC33D. I would change the oil when the engine was hot so it drained quickly and completely. I would think that the hot engine would thin the new oil so it ran down to the crankcase quickly too.

Thank you @Halftrack !

So, it looks like adding new oil at a rate less than about 2 quarts/minute is the recommendation. I'll go even slower than that.

It's real. A known problem with that series of TC engines. Lots has been written about it. It's a design feaure...er, problem or whatever.

Oil will always pool, especally when pouring in new cold oil too rapidly. On that engine, pouring oil in too rapidly can cause oil to overflow into an intake intake manifold passage that should have been designed to be a little higher.

Cure is to not do that....pour slowly. Probably good practice in any engine.

This is not an issue. I owned a TC33D for 22 years with over 2500 hours of use, did countless oil changes myself and never had a problem as described in the OP.

I believe it can happen if say one takes a gallon jug and tips it into the fill point. However, I don’t do that and I do pull the dipstick out like the service bulletin says to do.
