I thought I would share my experience installing the EOC Oil Separator for 3.0 Diesel as a part of the reliability modifications.

There is a video out there from EOC describing how it is done but there are a couple observations that I noticed worth mentioning.

All you have to do is make one cut on the PCV line to splice their hoses. I believe some of the videos they reduce length of one of the hoses but I did not find it necessary.

To make the cut, you install the top hose on the Oil Separator into position and undo the PCV hose from the block end toward the front of the vehicle, then gauge the new hose and the existing hose with each other and make the cut right where they would meet. It has enough slack to accommodate additional length introduced by the connector.

I ended up painting the bracket to make it little more OEM.

Overall, good quality of parts and things lined up well. I believe one of the videos from YouTube pointed out the bracket rubs the radiator, I did not find that issue with my case.

One thing that I had to do is the radiator mounting bolt has fender washer built in. This washer was too large to be reused so I had to cut part of the washer to clear the mounting bracket.

I've been thinking about doing this. Let us know if you get any CEL's. A few have reported getting them.

I must be getting old. I love OEM look. Used Rust-Oleum self etch primer and textured paint.

Put on several hundred miles since the install. No CEL.

Great job. I installed mine 18 months ago. No CELs.
Catches about 1 tablespoon per 6K. Use a paper towel to drain.
Good to know. Thank you!

I initially tried to turn the drain by hand but boy it closed on there tight. Had to break it loose with a wrench.

It is pricy but I got it because this one is known to not cause check engine light and it has been working fine.

My thought is that this oil catch can relocates the sensor and that is likely the trick to not getting the check engine light. Generic oil catch can does not relocate the sensor.

Understandable and in the bigger scheme, lets be honest, it is expensive, but so is the Gladi, so one can argue it's stomachable if it works

I am no way against modifying my truck but how important can it be to keep 1 tbl spoon of oil from going through the intake of a diesel every 6K miles? I will most likely buy the catch can anyway though.
