Washable Air Filter and Intake Mod , With Larger Breather

[Diesel911]

While I had plans to modify the intake to take Fram WA8039 washable Air Filter I had not planned to do this soon. The job started with me only wanting to replace the Turbo Charger Drain Seals and at the same time flatten out my Oil Pan that the Previous Owner dented by Jacking up the Engine there.

While I was dealing with the Turbo Drain I realized that the Breather Drain was also leaking Oil.

However, when I tried to remove it I found that a Bracket prevented the Drain Tube from being removed being removed and that the upper Nut and Bolt that held the Bracken on were Frozen and had a rounded off Nut on it.

This necessitated the removal of the Turbo. To allow me to use my first time ever use of an External Ezee Outs on the Rounded bolt; it worked fine.

Having the Blow By Drain Tube off reminded me that if I did my Air Filter Mod I that there was a good chance I would have to change the Blow By Drain System.

The area between the Turbo Drain Tube and the Blow By Drain Tube is extremely cramped so I felt that since I had all that stuff off and had bought the Air Filter about 2 weeks previously I decided to do the Air Filter Mod.

With the exception of having to drive around to several Hardware stores for the ABS plumbing parts the Air Filter Intake was relatively easy.; and, I found that the ID of the Air Filter Gripped tightly around the 4”to 2”ABS Reducer Bushing and that connected to a 2” 90 degree Elbow with a short piece of 2” straight pipe on it.
A 2” Hub-less Rubber Sleeve with Hose Clamps had to be shortened a little but worked fine to attach the Intake to the Turbo.

It turned out that deciding which way to go to make another Breather and how I was going to get it to fit was the hard part.
I knew that I wanted a larger Breather and started off trying to use a 4” by 12” section of ABS with end caps on it. But, I decided that it did not fit well and mounting and setting up the Drain would be more difficult; partly due to the Turbo being under that area.
So I decided to stick with the Stock Breather Drain to save me any plumbing issues.

(I also thought about turning the complete Air Filter Housing into a Breather but decided not to as I would have to do some cutting on it.)
So I came up with the idea of using the Cookie Can as a housing for the Breather. This allowed me to use the Stock Breather Drain.
I also needed to pipe the Blow By into the Air filter Intake and did that with a Plastic Nipple held in with JB Weld.

What was accomplished:
I had previously been using a K&N Air Filter (that fit the stock Federal Air Filter Housing) because the Oil from the Blow By was soaking the stock Air Filter Element and shortening the life of it. With the K&N that uses Oil anyway I felt it would continue working and remain usable.

Everyone claims the K&N does not filter well and you need to clean and recharge it with Oil which is an additional expense.

So a possible replacement came along with the Fram Washable Air Filters (I also bought one that is a direct fit for my Van and modified the Volvo for the WA8039 washable Air Filter). It has the good filtration of the Paper Element Filters but can be washed in Dish Soap and does not need to be recharged with Oil as the K&N one does.

In an Old thread on the subject I disproved the “ Hot Air Intake” idea. Heat only builds up under the Hood at Idle. While my Car was moving; even in City Traffic the under the Hood temp is about 5 degrees higher than the outside temp.
