I don't think this is that serious...but. Anyway, got a '63 IH B414 diesel that seems to be sucking the oil out of the air cleaner into the sump. It has a new fuel pump (fixed that problem!). I have had the injectors rebuilt (no more smoke) and checked the injector pump seal for leaks, none detected. But the pipe from the intake manifold to the cover plate on the injector plate runs oil AND there is a little more oil in the sump every time I run the tractor. I'm thinking that the oil has to be coming from the air cleaner. I'd just as soon have a paper filter, but I can only get half of the steel wool element out of the canister. Any thoughts? You all have been a big help in the past. Thanks, Joe

Ya know, I have realized I misread your post completely. Your diesel tractor is gaining oil in the oil pan right? Check the primary fuel pump for a leaking diaphram. I replaced the fuel pump on my MF 165 last month after discovering the motor oil level was way above the full mark.

You mention about being able to remove the wire-mesh from only half your filter. The wire-mesh in the upper half of your cleaner in perminately installed and not intended to be removed. Only the mesh which fits into the lower bowl can be removed. In order to clean the upper unit properly, remove the unit from the tractor and soak it in a pail of diesel fuel in order to release the crud. Flush several times with clean fuel and you've got a renewed filter that will be good for years if you replace the cup oil to the proper level with new engine oil at every schedueled engine oil change. Remember, those old filters were standard issue for decades and decades and in my humble opinion are hard to beat if properly maintained , just like your tractor.

Appreciate the help, still baffled. I am using 30 W in the air filter, it has been removed and cleaned, and the pipe that runs to the injector pump is on the manifold prior to the combustion chambers...why does it have oil in it? I'll tell you, I'm plenty worried that the added oil is really diesel and I'm setting up for a big ol' repair bill. Oh yeah, one other thing, at top RPM under light load (running up and down the road) the engine developes a miss, I've been told that the governor will do that to the engine. Don't know.
Thanks again, Joe

Firstly, I disagree re the efficiency of oil bath v paper element air filters. But, nevertheless, you should be burning that oil, and smoking, before the oil could get from the cleaner bath to the sump as it would be drawn into the combustion chamber, wouldn't it?
If the element was badly blocked, to produce a high vacuum, I would also suspect black smoke to be produced.
The air cleaner oil level will be dropping faster than the engine oil level is rising, so you should be confident that the oil is leaving the cleaner - normally the air cleaner level will not change very much at all. Hope this helps, but am baffled with your symptoms and not a B414 user
Regards, RAB

Oil bath air filters are much more efficient at removing contaminats from the intake air vs paper element units. The usual cause of the intake sucking the oil from the breather filter is using too light oil. I use 30w30 oil year around in my tractors with good results.

What labratory test are quoting for a Donaldson oilbath at rated flow, oil wetted mesh ( K&N) and a quality (not a walmart) dry filter?
