So I guess pcv valve is holding fairly well under positive pressure. So as the intake manifold and underside of throttle plate are filthy I can only assume this is all coming in via pcv under vacuum. As a daily driver the manifold is in vacuum quite a bit...otherwise known as Brisbane traffic. So my questions are is this a normal amount for a 96k km vehicle(g6et) and is anybody running a catch can from pcv to manifold with the check on the outlet of the can and with what results? Or maybe a double can setup? I see most single cans are on breather to intake which makes sense if your in the boost alot,like a track car would be, or you have tons of blow by on an N/A pos . I'm thinking double baffled cans to stay emissions legal and keep the oil out of the inlet entirely. If this is normal which I suspect it is in higher k engines then why the feck did ford not just fit a freaking stupid little can you could empty at service intervals? That's a rhetorical. Question btw. Also I'd recommend checking the pcv at regular intervals and cleaning/ replacing as required. It's a check valve in a boosted application(has a spring in N/A applications I think)and mine was passing a little just under the pressure of my lungs let alone boost pressure.I was not able to make it pass after cleaning it.(don't suck through it after drowning it in carb cleaner like I did, wasted half a stubbie rinsing that sh*t out...) It's a potential boost leak and will also result in positive crank case pressure blowing crap out the breather and back into your turbo. End rant.

A catch can on the pcv valve will fix itI run one on both circuits. And a big one way valve as well ( silver valve next to crankcase breather) Edited 09/02/14 04:16 PM by arronm Link to comment Share on other sites More sharing options...
turbotrana Member 2,586 Member For: 21y 10m 9d Gender: Male Posted 09/02/14 04:20 PM Share Posted 09/02/14 04:20 PM I've built them for my hi-po engines. Oil catch can on the PCV side (idle, light cruise) and one on the engine overflow side (under load).The pic is for the PCV side. I put the stainless scrubbers inbetween the perforated tube and the air has to go from the outside void to the inside void. It traps 95% of oil. I also have a set of one way valves that allow oil to drain back into the sump on shut down.I need to do one for my FG as mine is just like yours.

The can I have on the PCV valve circuit is actually an oil separator and works great. The cheap catch cans really dont work that well. The oily air really needs to travel through a medium to work properly as turbotrana explained. Link to comment Share on other sites More sharing options...

Apparently short trips compound sludge problems as oil needs to get to 221 degrees to vaporise contaminates, which takes around 20mins. Add to this ford's 15k service intervals and you got yourself sludge. Ask my dead turbo about it...screen blocked and banjo full of sludge...thanks ford. I think arronm's setup is ideal and will keep 95% of sh*t out of the inlet whilst remaining emissions legal. Any idea what it cost mate? Been looking at the areoflow cans on fleebay. Baffled, $119.

Keeps all the oil out of the intake / turbo system. Done it many years ago.Its the PCV valve circuit that leaves oil pools in the intake runners.The crankcase breather (your circuit ) if not filtered coats the turbo and intercooler internals with oil.
