D17 Blowby

Hello all. I own a 1961 D17 series 1 diesel. My problem is this. The tractor spits oil out of the filler tube badly. The cap fits pretty tight but as you know it also acts as a breather of sorts for the crankcase. Why would it be throwing oil from there like it is.......it is so bad that i have to stop every couple hrs and add a quart.......any suggestions......

Our D17IV slobbered oil out of the filler after rebuild. To remedy the situation, I put some steel wool in the filler pipe to obstruct the oil. This worked! This is not my original idea - I had read is some publication that an Allis engineer was working on stopping this migration of oil out of the filler tube and this is what he came up with. Using a label maker, I have instructions posted on the filler cap to remove the steel wool before adding oil. Tom

The filler tube and cap is also the crankcase breather and pressure release for the crankcase. Loose valve guides on a diesel which is a very high compression engine will allow excess compression to enter the crankcase which will be vented thru the filler tube,ie blowing Oil . Loose piston and/or rings or damaged cylinder liner will cause a noticeable loss of power or a hard start situation.If tractor starts and runs decent I would suspect excess valve guide wear. This often happens when a valve Rrefacing and seat grinding only are done in order to make a tractor run well to sell to any one unsuspecting .Valve guides are often ignored as are lifters and push rods etc. The customer hears a well running tractor and is none the wiser.

It sure sounds like compression in the crankcase to me. If so, an overhaul is in order.

Itís amazing how a little floor jack can lift tons and tons of weight with just the flick of a handle. Whatís even more amazing is that all the principals of hydraulic theory can be wrapped up in such a small package. This same package applies to any hydraulic system from the largest bulldozer to the oldest and smallest tractor. This short series will take a look at the basic layout of a simple hydraul ...
