Hi...
I've been looking and looking and cannot find my answer on the forums or online.
What does the hose coming from the oil filler cap, going into the air intake do?
Everyone seems to be installing their catch can on the left side of the engine to the other ports.
My hose is removed from the oil fill cap location, and replaced with a stand alone filter, it is no longer feeding into the air intake.
So here is my question....
-what is that going back into the air intake for?
-why is everyone installing the catch can on the left side of the engine?
-it seems the hose feeding back into the air intake would be throwing oil spray through my air intake and into the throttle body?
So is something wrong and that is why my filter is getting saturated (where the hose used to feed back into the air intake)?
And, also why would you want all that crap going into your air intake?:serious:
erm.....the catch can fits on the right of the engine (seen from the driver's seat).
No-one wants 'all that crap' going into the intake....it retards the ignition. Thats why we fit a catch can.
The factory is obliged to recirculate the oily vapour from the crankcase to be burned for environmental reasons. In days gone by cars would just let it drip. So the PCV and oil filler neck feed back into the system to achieve a 'closed loop'. They dont fit a catch can as standard because it obligates the owner to empty the thing occasionally. The way they set it up, a dimwit can't muck it up
your little filter will probably be wet for a couple of reasons....1st is that your oil level is on the high or low side - if its low it will 'churn' more readily as the crank turns. Too high - speaks for itself. 2nd - if the oil is a lighter weight, or its a hot climate, the thinner oil will be easier to beat into a vapour suspension
Right, I follow you there. It seems it could almost use a dual catch can set up.
Also, I have a question I cannot seem to find instructions on for our SRT engines...
The tube at the top of the engine right behind the throttle body.... is that what they are referring to as the "intake manifold"?
And, the tube on the lower side where the catch can is installed, is that the PCV valve?
So the lower PCV valve is to connect to the input side of the catch can, and the output goes to the top side to the inlet right by the throttle body?
I've watched all the youtube videos for our Gen 1 SRTs, and no one specifies this (probably because its obvious to everyone else), and no one states which should be to the input/output of the catch can.
Any guidance is appreciated.
I'd like to post pictures of all my high mileage maintenance I'm doing, but seems the forum's drag attach files section isn't working for me.
It is installed on the right side of the engine which provides for the shortest run of hose from the PCV & intake manifold to the can.
The catch can will function with either hose attached to either connection on the top of the can. It simply "catches" the oil filled vapors when placed in the PCV circuit. There is no specific "input" or "output" side of the can.
Oh sweet okay. Got her installed... I'm thinking of installing a second catch can from the "breather" near the oil fill cap (which used to feed into the intake but I removed the line and just slapped a filter on it).
And see what I can eliminate and monitor as far as fluids... has anyone else done this?
I noticed a vacuum pulling into the intake manifold... so I just hooked my output into the intake manifold even though it probably is not an issue one way or another.
Can anyone advise how I can load pictures? The drag and drop section does not work for me.
I would really like to share things I've done with my car over the years.
I used to work at Ford Paint & Body, so I've always gone for subtle mods to the stock appearance. I have had about 3 different looks, and it is about to go into a 4th change.
Also, to post any mechanical changes or upgrades/fixes.
I only have one catch can as the breather on the left side of the engine simply provides a vent to the crankcase. I clean the filter routinely and have had very little material blow through it. I use a K&N there.
