Thats your slobber tube tank should be check and drained each oil change.

On a Detroit there are hoses coming from the side of the block three on each side while u are idling the oil that cools the Pistons runs into the tubes and goes into the tank. By checking this oil it will give u a indication of and water or sparkly things in the oil.

On mine the tank has a tube that comes out the top like a overflow that's why it should be drained each oil change.

No piston cooling on the Detroit 2-cycle. The two cycles run very low EGTs so don't need oil sprayers up to the pistons. The tank is for the air box drain. Reading the Wanderlodge forum, sounds like some have a blower problem that use oii. Ours used 2.5 quarts coast to coast and back.

So, you may or may not have a "slobber tank" that collects oil from the air box. Or the oil may just drip on the ground. If you have one, it's called an air box drain canister. Here is the PDF with a diagram: https://www.wanderlodgeownersgroup.com/downloads/Detroit_Diesel_Tips_Modifications/DETROIT%20DIESEL%20AIR%20BOX%20DRAIN%20KIT.pdf

Ours does not have a slobber tank but has a check valve that allows the oil to go back into the sump. If a Detroit fills the slobber tank or drains a lot on the ground, a blower bearing and seal may be bad allowing the blower oil to go into the blower box. Again, if your Detroit uses oil, it's not that the engine is tired but the blower needs attention.

While attending a Detroit seminar, we were told that if a blower bearing fails (from lack of regular oil changes), it may allow the Roots blower impellers to touch a bit. This generates a little aluminum dust. This dust may collect in the top piston compression ring's piston lands and may limit the ring's ability to move. This may require a set of pistons/liners.

Lots of rumors, wives tales, etc when it comes to engines. Get up to speed with reliable sources before believing too many forum posts from wannabe experts.

Well I will stick to what I know and it's worked for me along time from people that have years of experience with Detroits.

Andy: Got one of these myself. Going to crawl under rig tomorrow and look for this stuff. To be honest picture does not match anything I have seen. However I'm pretty sure I have something similar. I have a drain petcock in the frame rail under the radiator. Apparently it is a tank of some sort. Supposed to drain it at oil change. Maybe an ounce or two but nothing major. Will get some pics and update.

In any case you can look for yourself and we can compare notes. Plan is to hit " Q." 19th or 20th

Andy,

Not talking about you. I am a member of the Wonderlodge Forum and have been reading what some expert members have been talking about. Ask your mechanic buddies if they have ever seen or even found a part number for a Detroit 2 cycle oil squirter. 60 series, DD13, DD15, DD16 yes, 6V92TA no.

One of the airbox drain kits: Walker Airbox Drain Kit for Detroit Diesel (DDC) Engines -Part# AJ4120 –...

While many gasoline and diesel engines have oil squirters, the Detroit 2 cycle does not. Some 4 cycles have a hollow dome piston where the oil is squirted up in into the hollow piston dome and drains back out of the other side of the piston. The piston has to be made in two pieces and then welded together so there is a hollow passage for the oil to be squirted up into. The squirters are down by the main bearing caps on Cummins, Detroit 4 cycles, Honda gas cars, Mercedes, etc, etc.

Detroit Diesel 2 cycles have the normal passage from the rod bearings up to the piston pin, then there is a very short passage above the piston pin to the very top of the connecting rod where a small hole is. Oil is sprayed out of that hole to the bottom of the pistons cooling the piston. The two cycles don't require the nozzle down at the main bearing area as the blower supplies a huge amount of air to the engine on each stroke unlike a 4 cycle that fires every other stroke and only receives a much lesser amount of air on every other stroke. This is why the Detroit 2 cycles run a lower EGT and don't suffer the valve failure from high temperatures. Our 6V-92TA also has no intake valves, just unrestricted holes/ports in the sides of the cylinder. The 4 valves are in the cylinder head are all exhaust valves and as they are four small valves, the distance the heat has to travel from the valve head to the stem is very short so the heat in the head has a very short distance to travel to be dissipated into the stem. The low EGTs can be seen in several dyno tests on the 2 cycle Detroits.

So, the air box drains oil to the ground or into a tank and has nothing to do with oil squirters shooting oil up to the bottom of the piston.

Lots of photos of oil squirters here: oil squirters detroit 60 engine - Google Search

On my old 6v92 in my Wanderlodge, there would never be any rust forming in the engine compartment

Ours is almost spotless. You probably didn't have a catch tank (slobber) for the air box oil. But you did have a real block heater down by the AC compressor unlike ours.

When we bought our U300, there was nothing but negative talk on this forum about oil leaks, poor mileage, etc. Almost all was what a friend said,  a friend of a friend or a forum article where everyone becomes an overnight expert in engines or medicine. Since I have been driving and maintaining the Detroit 2 cycles since the late 1960's, I was amazed at what I was hearing and felt I had to bring members, especially other U300 members up to speed.

You don't have to spend the cash for the Walker or any other drain kit for the air box. A piece of PVC with ends glued on, a drain valve and a vent will work nicely and keep any garage floor clean. If you don't have a drain tank and have check valves instead, they could stick and pressurize the crankcase causing oil leaks.

Detroit owners have long enjoyed an almost vibration free engine from idle to fuel cutoff. Much of the smoothness can be attributed to the fact that 2 cycles fire every revolution so a 6 cylinder is like a 12 cylinder and the 16 cylinder version of the 92 series is like a 32 cylinder. But this and piston oil cooling is tied together here. The 2 cycle always has positive pressure (from the Roots blower) on the pistons, rods, bearing, etc but especially the piston pin. What's so special about the piston pin? When there is no reversal of thrust like in a 4 cycle on the exhaust stroke, the bearings, etc continue to be supplied by oil. But the piston pin would have no pressure lubrication and since there is no thrust reversal, it would not get enough lubrication from any splash, etc. So, Detroit drilled a small hole up the connecting rod to the piston pin so it gets pressure from the rod bearing area and lives a long life. This small hole is continued on the upper side of the pin and allows oil to be lightly sprayed on the underside of the piston crown. In other words, the lack of thrust reversal helped make the engine even smoother but/and also made the piston pin pressure lubrication a necessity.
