Oil separators / catch cans

[Bobsp12]

Did you blow through the catch can discharge side hose to make sure the check valve is working correctly?

Blow - it should pop open, suck, and it will close.

6000 km's on mine, no issues.

Might put the original hose on at some stage and go for a drive to see if I can feel any difference.
[MENTION=14692]Aus-MustangGT[/MENTION], how's your UPR catch can going? [MENTION=15083]Bobsp12[/MENTION] what about yours?

No issues with mine at all.....its still collecting oil.

but Im sure the car now has 600HP :bolt:

I have noticed that everyone has 600HP when the roads are wet around here.

Someone has probably answered this somewhere, but what does Ford Australia think of this mod? Don't want to have something major go wrong in the engine and they say, sorry, you're modification caused it or some such crap.

From the amount of oil I'm seeing above, it looks like it's almost a must-have.

My car started acting strange only after installing the UPR catch CAN. So I took it off and all back to normal.
Yes it was installed as per install guide and you tube install videos. The hose on the CAN end were supplied connected already by UPR and I triple checked everything is connected the way it should be.
I only did around 100 KMs after installing it and noticed car started missing at startup and idling too.
Since this was the only change I made, I pulled the CAN out and it's back to Normal.

Does anyone else have something similar experience with UPR catch can? I sent a PM to Steve @UPR, no response yet. May be he is on holidays or something.
So I thought I should take advantage of the knowledge bank of fellow members.

Can anyone shed some light on this issue, please.

Difficult to say Kaps, sounds odd, but given that the whole PCV system works on a vacuum principle, I wonder if your connections were dodgy/not well manufactured and whether there's a vacuum leak of sorts (I'm guessing you didn't see any visible oil coming out) that's resulting in odd data being fed back to the ECU. Could be altering the timing/ignition as a result, hence lumpy idle. Either try again, or get them to replace it. Not a mechanic though, so there may be something else at play here.

thanks for the feedback mate, really appreciate it. I was reluctant to take it off considering the fact, how much oil they collect. But that was the only way to test it.
God knows if its the hose, valve or the CAN itself.

I might try putting it back and give it another go.

Still haven't heard from Steve@UPR though, he must be on holidays

I noticed you are in GC too, want to catch up sometime?

Given Ford Racing Performance has their own unit, I can't see Ford having a big problem with one...

Of course, I'm not a lawyer, blah blah.

Kaps,
I will venture a few thoughts that may help. I don't have my Mustang yet, so I can't speak from experience with this engine. My understanding of the Coyote engine (from web research) is that the PCV Valve is located in the top of the r/hand rocker box (where you attach the hose to your catch can). This means that the entire catch can and hoses are directly connected to your intake manifold. This is significant in that if any of your connections are loose (or not correctly seated), you will draw air directly from atmosphere into your intake manifold. This will have the effect of reducing the vacuum in the intake manifold and giving you a "rough idle". The same problem will be felt if the catch can itself is not entirely sealed (loose cover etc). I would carefully check all of the hose connections and the catch can itself to ensure that they are air tight, then refit it as suggested by others above. Make sure that the two connections into the engine (rocker box end and manifold end) connect and seal.
Hope it works for you.

I did ask my dealer about this actually and the response was 'Possibly, if something goes wrong within the engine - it would be what they call consequential damage, if they can make a connection to any damage from any part that is fitted'.
The big thing for me is that Ford do make and sell their own version of a catch can, and because of that I would hope the argument would be mute. They just kept the cost down by choosing not to supply these on our cars in my humble opinion. I didn't buy the Ford one because I didn't like the idea of having to undo 4 screws with the possibility of dropping them into the engine bay, and then using a syringe to empty the thing.

Just remember the dealer doesn't need to know you have it.

Keep the original hoses, re-attach for dealer servicing.

... and never mention Mustang forums to the dealer?

I believe that it is highly unlikely that a catch can would do anything but improve the health of an engine. The areas of concern would be the catch can allowing unfiltered air to enter the intake manifold (via loose connections, rubbed hoses, loose lid etc). I would suggest that any owners with catch cans that are not positively supported (by brackets attaching them to the engine or chassis) keep a close eye on the condition of hoses over time. The continual thermal cycling of the engine bay, added to the additional role of supporting the weight of the catch can could lead to problems after a couple of years.

haha I can see your point, but to be honest it's a bit all over the shop with the dealers.

Everytime I mention "on the forums...this is a common problem" or similar, the dealer says "don't believe everything you read on the forums".

No worries then - except for the fact that all of the information gained from this forum has been infinitely more useful than any Ford representative.

I'm certainly not bagging out my dealership, they've been really good, but in the end they need to 'diagnose' things and see it for themselves, instead of listening to my smart arse comments about the fact that i'd seen the problem before.

My car is stock

I spoke with the same person as you tantash as your conversation came up while I was querying the same thing. I mentioned the ford performance one as my preferred choice as per your logic as well and the response was "If Ford AU don't make or approve the part they could still use it against you".

Imho that sounds like bs as the entire car is made in the USA...but I guess anything to pick on in case of a failure.

I'm at Robina. Home of shopping centres and roundabouts!! I think there's a PM thing to get in contact. Got to run as wife has demanded I buy baby crap but, yeah, why not?

Let us know how you go with the catch can issue.
