PRT PCV oil separator *interest check*

I should be in for 1!

I want to do a UIM/LIM rebuild on the SVT as i'm pretty sure it's never been done before. This would be a nice addition to keep things from getting built up again!

With all due respect to those who claim they've never had any oil in the accordian tube (coming from the valve cover vents) I found it there every time I looked. Not only that, I've spoken with other Tour owners who have had a similiar experience. I've owned 2 different Tours with well over 10 yrs. of "experiences". Now I push my car very hard in the twisty bits especially on track days. Hard RH cornering makes the oil splash/slosh up into the vent tube(s), past the baffle and then the negative pressure in the accordian tube takes care of sucking it into the intake tract. I find oil in the accordian tube, the throttle body and the MAF.

I made a oil & H2O filter/seperator with parts from H Depot. The only difficult part was the mounting bracket. It s/b mounted somewhere with good accessibility so that you can clean the oil/H2O out on a regular basis. Mine's mounted under the accordian tube with a custom fab'd stainless bracket. Now you shouldn't have to worry about H2O with an EGR seperator, but if you plumb 1 in to the valve cover vent you will.

My experience is that in the summer, I only pull oil out of the seperator. During the other 3 seasons, I mostly pull H2O out of it with a bit of oil mixed in for good measure. If it's rainy, I have to empty it at least once per week, if not more often! Also, I've noticed the oil stays clean for a longer period of time with it installed.

I'll take a pic or 2 and post here if anyone's interested.

Brad:
I'd like to see this set-up.
I also sent you a PM about SFCs, please get back to me asap.

I'm a little behind on the bracket with another project, but it is partially complete. I intend to finish it this week and post pictures Monday. Sorry for the wait guys.

Pricing is looking to be under $40 shipped. :cool: I'm also looking into some powder coating equipment so there may be some finish options.

Sorry for the delay, been busy with other stuff. Find attached my oil/H2O filter/seperator pic.

Total outlay approx. $15 for the filter/seperator assembly and 2 brass fittings. Of course, the other parts (.375" hose, plastic fittings and the stainless sheet metal) I had kicking around. You'll notice that the canister is in need of emptying...

now do you have both valve cover breathers attached to one filter or do you have 2 filters?



i guess ill keep my stuff i picked up but still pick up yours josh. the filter i got says max temp is 120* deg.

That's part of why i had a few people long-term test them. The 120* is OK. It was one of my concerns, but doesn't seem to be an issue.

I know you can't see in the pic, but both valve covers lead to a T fitting, which in turn leads to the IN side of the filter/seperator. OUT on the filter connects to the front inlet in the accordian tube. The rear inlet on the accordian tube is plugged with a turned AL fitting. In instances like this, it helps to be a machinist.

As I said before, the main problem is mounting it in a location with accessibilty and not having the plastic housing touching anything. It's also a good idea to replace the rubber O ring in the seperator with a Viton one. The combination of oil and heat causes it to distort, which eventually causes the seal to leak leading to a CEL for an air leak/lean condition.

Uh oh, another question. What's a Viton O ring? Is it a brand or a type of O ring?

thats what i was looking for, thanks

the top of my filter is aluminum so tapping the 2 holes in it will be easy for a mounting bracket.
 
Guys, I'm sorry for the delays but the bracket will not be ready until next week. I'm in a major crunch and i need to get my winter beater finished this week as my SVT is having some minor problems and it needs to be off the road before the snow flies. It's a simple piece to make, i just need to find time this week to get it done.

Also, i will look into replacing the o-rings that come standard on the separators as well as configuring another bracket layout and fitting arrangement that will accommodate (2) separators for those wishing to vent the VC's as well. :cool:

Thank you for your patience and understanding.

~Josh
 
you know what might be a good idea? sending 2 upgraded o-rings with each filter. if it needs to be at a additional cost. one for back up.
