Mike, sounds like you have developed pressure in your engine some how with your home made set up. the blow by pressures in the engine have to be released through the vent hose in the top of the valve cover.

One indicator was the kinked hose you found and the oil shooting out the dip stick tube when you checked the oil. I suspect the large amounts of white smoke was engine oil being pushed out of a seal in a large amount and being burned. leave this long enough and you will have leaks in other seals and it can shut down the engine with the internal pressure pushing against the fuel shut off valve.

The way you have the blow by plumbed into the intake between the air filter and turbo is the same way the 78 & 79 300SD were plumbed. they have it going straight into the "U" Tube between the air filter and turbo.

So recheck you set up and look for the restriction.

The 2 "O" rings on the oil filter lid stalk is not the problem. they keep the oil from draining from the filter when the engine is shut off.

Also put in your signature the type of car/model etc,,, you are talking about. I looked in your sig and noted you have a 84 300D.
