The inline fuel filters DO NOT have a check valve. Air can move freely in both directions (I actually verified this with a hand pump). I am not even sure why they have a directional arrow on them in the first place...

 

I just changed my pcv valve and I still have the problem with the dipstick popping up. I did a compression check and it was 185-189 between all cylinders. I was going to go with the dual catch can to eliminate the pressure.

 

From your other post referring to the filters you use.

"They are unidirectional (they flow one way) so be sure to place the arrow towards the intake tract (i.e. the blowby is flowing FROM the valve cover TO the intake for recombustion)."

 

By uni-directional, I meant that they had an arrow on them. I am still not sure if they are unidirectional or not. The arrow implies that there is a certain orientation that should be used for the filters, however if you blow through each side, air comes out the other side (both sides flow easily).

 

I got a catch inline from PVCC valve to manifold (catches about 0.5ml/day) and one on the (preturbo) intake side - between rocker cover and HKS RS (catches one drop/month).

One thing profound is the fact that from day one of car use, the tailpipe bumper area has been black, after washing the bumper - ever since catch installed - bumper remains clean!

 

+1 thats what ARC instructed. Mine also has a 3rd line that acts as a dump valve.

 

I haven't checked the valve yet, but under consistent hard driving conditions(20+psi) my oil level in my engine will go down an decent amount. Is it possible that there is so much pressure in the case that im accually blowing good oil out of my breather tube? Under normal driving my car will not use ANY oil...even if i hit it once in a while.

 

I would rather keep my catch can "lower" than the way the Weapon R is mounted. You will find it hard for the blow by to travel in the upward direction. Ideally you want it mounted in a lower location.

This setup worked best for me.... very short distance for the blow by to travel. Worked real well.


My current setup. I need one more.

 

revvin9k how much oil does that system catch for you?

 

Not too much to even consider, just gives me piece of mind knowing that my intake does'nt look like it did before I had the catch can. It was coated.

 

Is there anything between the inlet and outlet?

 

Not really sure what ur asking me.

If you're asking if there is residue inside the can then yes. That was the main reason I switched cans, so I can actually open it and take a look inside.

 

I mean like baffles or steal wool.
