Oil Catch Can vs. Breather

Who can help me out here? I've never had experience with either. Which one do you all recommend? How do they both work? Any info would be great

Breathers are the only way to go. Just make sure you remove the check valve ( little metal ball and a small pin) on the passenger side pcv fitting coming out of the coil cover.

The catch cans suck. They still let oil into the intake.

And no the breathers do not let oil onto your valve covers

Breathers are cheaper when you think about all the plumbing and mounting of a catch can.

Breathers are the way to go. If you want to save money, there are TONS on ebay that are exactly the same as blow by and JPC for a fraction of the cost.

12mm 1 2" 0 5" Gunmetal Grey Crankcase Vent Valve Cover Oil Air Breather Filter | eBay

You get the 12mm or 1/2" grommet. Also on the passenger side, you can trim the valve stim downa 1/2" so the filter sits lower to the coil cover.

Finally got off my *** and did it this afternoon. I trimmed down the passenger side PCV about 1.5cm so it didn't stick up, and also removed the checkvalve inside it.

Quick note, normal vacuum caps won't cover the holes left in the intake and the engine side of the pcv hose. They are about 1/2", and the 'advance o'reilly zones' around my area didn't carry vacuum caps that were any bigger than 3/8". I had to get a cap meant for the cooling system to fit. Looks great, fits perfectly.

Might eventually paint the passenger side PCV valve to something other than bright blue at some point. Just me being OCD I guess.

----edit----
The breathers I used were the el cheapo ones at O'reillys. Spectre, part number 3991. Watch your fingers when drilling out the bung to 1/2", I about made a nice hole in my dumb hand today.

Aye, they weren't with the normal vacuum caps. Had to go over near the area with the cooling system hoses and fluids to find what I needed.

The breathers delete the lines that go to the air intake right? Those aren't needed? & do the filters eventually have to be changed at all?

No the lines are not needed. All you have to so is clean the filters. Just like a CAI.

The catch cans are a ripoff, for people that are sold on advertising and such. Aka have no clue about ****

I figured a cleaning like a CAI would do..Awesome thanks! Yea they seam expensive for what they are..the breathers look way better IMO! I've quickly figured out doing your research before being anything will save u lost of $ & headaches in the long run.

You only need one catch can or breather filter, and that's on the passenger side. The drivers side is where the engine draws air into the crankcase, so that side drawing air from the stock tube via the air intake to the engine cover is fine. Adding one for looks or "balance" works though.

The passenger side is the culprit for the oil mist, so either a catch can (you can make your own using the existing tube and plum in your own can) or the breather works. The breather will need to be cleaned, and yes, it will eventually dump oil onto the passenger side engine cover if you don't clean it. With around 650 highway miles I frive a month, I see around 4 tablespoons of oil; that's alot for a breather filter to be expected to hold without periodic cleaning. Breathers are certainly the cheaper way to do it, just be sure to inspect them.

You do need 2 of them. For proper venting of the pcv gasses. Just Like you have to remove the check valve on the passenger side . and if your getting 4 tablespoons in 650 miles you have a problem.

There an oil consumption issue with the 5.0 that would require changes to the PCV system?

They have blow by stock. The 4 tablespoons in 600 miles is ridiculous. Best way to properly eliminate oil going back to the intake is with breathers, Also alows the pcv gasses to properly vent.

This fairly common? Granted I only have 700 miles on my 5.0. She's still full.

BTW. Whoever decided to put the dipstick in its current location. Should be dragged into the street and shot.

Thanks for the heads up.

The Magnum 360's have similar issues. I fixed it with a baffled canister. Completely stopped my oil consumption and anything that did make its way into the canister. Drained back into the motor.

If my 5.0 exhibits this behavior I'll have to try it again.

Not to hijack the thread, but I didn't see this mentioned on the 3.7 side. Are these available for us 3.7 guys?

Examine the crankcase ventilation setup. On the drivers side, theres a tube that runs from near the air cleaner box (stock) or CAI tube to the drivers side head cover. This is the engines crankcase intake. On the right side (passenger), the crankcase gases/oil mist is drawn out via the PCV valve, through a tube that connects to the intake.

It is on this side that the oil vapor is going to exist, nothing on the drivers side.

Since air is drawn in from the drivers side via the tube that runs near the air filter box to the head cover, you don't need a breather on that side, but by installing one, it makes the engine bay look nice and balanced with the one thats required on the passenger side.

Either a breather or a can works. Your choice.

I've had a catch can on my 3.7 since it had 2K on it back in 2011. It now has 59K, and I've emptied anywhere from a few tablespoons to about 4 within a months driving. Can't say this would be the case with the 5.0's but it is the case with my 3.7. If I do city driving, it's less, but with highway driving of 70 MPH plus, It captures more.

It does not matter to me if you go the route of a breather or a catch can, but the passenger side is where the oil mist is going to be captured.


Here's a few links to read on your own:

http://www.teamshelby.com/forums/ind...s-really-work/

Look here at post #5...only 90 miles on a 5.0:

http://forums.themustangsource.com/f...erator-490315/

And many posts on the subject with catch cans, breathers, and some homemade units to keep the oil mist out of the intake:

http://forums.themustangsource.com/f...528638/index2/

I don't care what you go with, but keeping it (oil mist) out of your intake is a good idea. If your a non believer, borrow onr from your friend who installed one, run it for about 200 to 300 miles, then see how much oil it captured. You'll be a believer then. And there's nothing wrong with the engine; they produce oil mist.
