...look at the last note in the catch can instructions. What Say You To That?

 

My catch can used to make an annoying whistle with the fixed orifice PCV valve also...I talked to the guys at AMW and they suggested that I switch back to the original style PCV valve (spring and plunger). The noise went away and the can's been working great

 

take the oil cap off while its running, if the sound changes that = pcv i hear that same wislting in my truck cause i have a 04 6.0 ( FOT no wonder i couldnt find the pcv valve on the new 6.0)

 

are you taling about the forced induction part? if so there is away around that. let me know if you wanna know how. and it will provide better cank case ventilation

 

Talk To Us.

 

Sorry guys but whats the benefit of a catch can. I know alot of pressure builds up in the crankcase but why do you need it?

 

let me se if i can still find the diagram for easier explanation gimmie a min

 

ok can't find it but i'll try to explain. you have two vent one pcv except for ours i guess and the vent on the passenger side. route both of those to a "T" fitting then to your catch can then from the catch can go to your intake piping ( before turbo intake or before supercharger intake) the get a small piece of hard tubing like 1/4" i guess and slash cut it at about a 45* angle then insert that into the intake tubing with the slash cut pointing toward the turbo intake or supercharger intake. this will couse a venturing affect (a vacuum from the air passing by it) this will create a vacuum in the crankcase lowering blowby and crank windage. inturn less resistance on the rotateing assembly releaseing hp.

 

but you want a catch before you do this or else you with get a lot of oil o the turbo or supercharger

 

the catch can is to pull the oil out of the air from the pcv before it goes to the intake helps keep the intake clean
