Oil Catch Cans
 

Thinking of ordering an oil catch can.

So which one should I go with? Moshomoto or Morrosso? The latter is 50 bucks more is it that much better?
Also probably will order from AM unless there's some other Canadian options for me, close to home and comparable price. If I order from AM there wont be any shipping since I'll go there and get it, so really just wondering what you guys got/think.

Also there's a NAPA in town, anyone know if they got stuff like this.......:)

I went with the JLT one, Nice clean good looking unit! Easy install plug and play! :tup

^^ cool thanks

And its even cheaper than the Moshimoto. Looks good under the hood. Is that where I'd mount it on my 4.6?

ummm I think it would mount here in this picture...

Cool thanks. Thats what I was thinking. Why do you have it on the passenger side of your 5.4, it was my understanding they should be on the drivers side as is in the photo you so nicely posted for me.

GT500's PCV is on passenger side.
My pal has one on each side of his shelby looks nice but no oil is ever found in the drivers side...
I usually recover 1/4 cup between oil changes.:tup

I've heard nothing but good things about the JLT

I have the JLT on my 06(drivers side), have had it for a long time. Looks good, works good, no problems.

Thanks for the reply's guys. I'll probably go with the JLT then, the price is right and looks good too.

I went with the JLT as well:

Where are you guys getting the JLT catch can? Hopefully a Canadian suppplier. I want to put one on mine too. I put a CC on my 09 Envoy but used an air filter with some of that copper pot scrubber inside. Works great but I want a better looking one for the 'stang.

Got mine from DaSilva Racing, ask for Joe or Matt tell them Scott sent you.

Thanks Scott. Looks like they offer lots of services! Very tempting as I can see by your mods.

Too tempting! lol

They just put up the online store last month. If you do not see the catch can for your car, just give them a call I know they can get it.

Oil separator pics
 

Pics of my oil separator set up...

Looks great, what do you use for hose connection on the intake and valve cover ends? Do you have any pictures of them?

I just cut the quick connect from the Roush PVC hose ends. I believe the stock quick connectors fit the -AN 10 hose The barbed connector ends slide right on with a bit of elbow grease and a touch of oil.I'm sure ford would have those barbed quick connect hose ends. I then taped the end of the hose after trimming and used a very small hose clamp. One is under the intake tube and one is at the back by the firewall.Very hard to see. Try for some pics tomorrow.

Some close up pictures would be great, thanks!

heres a couple
 

Here is a couple.Hope you can get the idea.

Great thanks and it is -10AN hose?

Yes -AN 10 hose

The JLT looks really nice. I used a commercial Air Filter from Princess Auto and tubed it in to see if I would get much oil. To my surprise I do catch about 1/3 cup of oil between changes. Most forums say you won't really catch anything unless your car is SC but mine is stock. I like keeping that oil mist out of the CAI and the TB seems to stay cleaner.

I havn't purchased one, honestly havn't done any motor mods at all, but I've heard the jlt or any of them don't catch everything. Some guys at S197forums.com actually have to in series or just put vents on the heads instead.

The type of hose is important. I originally used some 5/8" Goodyear rubber heater hose. I figured it was going to mostly air inside so it should work. Wrong! After a few months I noticed that this tubing was 'sweating' oil all over the outside of the hose. I replaced it with clear plastic tubing and that is working well and I can see what's inside the tubing although it is yellowing a bit. There is a small accumulation of oil around the fittings (elbows and connectors) as well as in the catch can of course. Interesting to see.

I tried a few different types of hose, they would either collapse or sweat oil. Finally went with hard tubing (same as the original PCV hose) & reused the factory fittings. Just used a little heat to custom bend it.

Little bit of an old thread, but ill add my experience here.

I've ran JLT and Steeda cans on my drivers side. Both trapped oil very well. I have also ran breathers...what a mess, slobbering oil out of the passenger more so than the drivers side...I assume because of the PCV valve in the drivers head stopping some of the oil.

I finally went back to a UPR catch can on my passenger side and a vent on the drivers side. I did this when I added the procharger, what I found was I was still getting oil into the system, so I hooked up my Steeda down stream of the UPR can. Its working very well now.

Maybe with non blown applications a vent set up will work better...but with forced induction I wouldn't recommend venting.

my 2 cents

Thanks for the input.

I am looking at a JLT mainly due to the plug and play factor with the hoses and connectors.
What are your thoughts on the JLT seeing as you had one?

Thanks

Go with JLT The one I have on the passenger side of my car looks great and actually catches oil I have the driver side on order right now.. I think they were the originator.

sorry I missed this post...the JLT was to small for my application. are you boostd? or N/A?

For a daily driver under normal conditions the JLT will be ok if you check it often. If you drive your car like I do, you will want a bigger can.

I went with Moroso, here’s what I did for my catch can:
The following parts were required for the install:
Moroso Catch Can – 85477 (comes with a mounting bracket) $129.00
5/8’’ Black Fuel rated Hose (NOT water hose)
NPT to 5/8 Barb Fittings (x2) $6
Stock PCV Tube $14
15/16 Corbin style hose clamps (4 required)

https://www.cmoc.ca/attachment.php?a...ine=1423675812

I choose the Moroso catch can because it came with a metal mounting bracket designed specifically for 05-09 Mustangs. The unit has a valve on the bottom that is used to drain any captured oil blow-by. I could have used braided hoses and colourful hose fittings but I wanted to keep the OEM look under the hood.

The threads on the catch can were very tight, preventing me from getting the barb fitting adapters threaded very far into the can. So I decided to loosen up the threads on the can using a 3/8-18 NPT pipe tap (previously used to tap a hole in my intake manifold for an IAT sensor relocation project).

https://www.cmoc.ca/attachment.php?a...ine=1423675812

I still wasn’t able to get the fittings screwed in far enough for my liking. So I purchased some black rubber o-rings to cover the exposed threads. I coated them with silicon lube to prevent them from drying out or cracking down the road.

https://www.cmoc.ca/attachment.php?a...ine=1423675812

Here’s the unit all assembled. I made sure to apply Teflon sealant to all the pipe threads.

https://www.cmoc.ca/attachment.php?a...ine=1423675812

The metal bracket that came with catch can was made of bare unpainted steel and would’ve been a major eye sore. So I painted the bracket with some stainless steel coloured metal paint; that just so happened to match the exterior paint under the hood.

I then attached the bracket to one of the strut tower bolts and re-torqued the bolt to spec.
Here’s the can mounted to the strut tower

Here’s the modified PCV hose that was added during the supercharger install. The stock PCV hose was much smaller in comparison. The supercharger required a much bigger hose (5/8th) to accommodate for the increased air flow.

https://www.cmoc.ca/attachment.php?a...ine=1423675812

And removed

https://www.cmoc.ca/attachment.php?a...ine=1423675812

For the hoses I followed the same procedure that I used for the supercharger install. As mentioned the hose diameter was increased to 5/8ths to account for the additional airflow. A black fuel rated hose was used for this purpose. The only issue with using rubber hose is that it can collapse under the heavy vacuum pressure created by the supercharger. The solution was to reinforce the hose with some solid tubing taken from the stock PCV hoses (the same method used in the whipple instructions). The existing reinforced PCV hose would be used to connect one end of the catch can to the intake, but a second hose was required to connect the catch can to the valve cover. So an additional stock PCV was purchased (Motorcraft Part# KVC166) to reinforce the second hose.

https://www.cmoc.ca/attachment.php?a...ine=1423675812

To modify the stock PCV hose I simply cut off the protective sleeve and the quick connect fittings

https://www.cmoc.ca/attachment.php?a...ine=1423675812

From there I measured out the length of hose required to connect the valve cover to the catch can (approximately 22’’). Then I cut the stock PCV tube in two pieces and inserted them into the new 5/8th hose where additional reinforcement was required. The stock PCV tube has a curve in it, so I made sure to position the curved tube where the hose would naturally curve when installed. Inserting the reinforcement tubing into the hose was by far the most difficult part of the install.

As mentioned the existing reinforced PCV hose would be used to connect the catch can to the intake manifold. The hose just needed to be trimmed down a bit (to approximately 11’’). From there I just attached the new quick connect fitting that came with the stock PCV tube using a couple 15/16th hose clamps. And that’s it for the hoses.

Here’s the original modified PCV hose running from the catch can to the intake manifold

https://www.cmoc.ca/attachment.php?a...ine=1423675812

And here’s the new PCV hose running from the catch can to the valve cover. The curved sections of the hose are where the curved PCV tubes were positioned to prevent kinks and to keep the hose from collapsing under heavy vacuum.

https://www.cmoc.ca/attachment.php?a...ine=1423675812

And that’s it. A simple modification that will help keep oil residue from baking onto the intake manifold, the intercooler core and any intake sensors. I drain the can every oil change and get about 1-2 table spoons of oil each time.

Definitely a good investment if you have a blower.

How is your passenger side routed?

I didn't add a catch can to the passenger side, it's just routed from the passenger side manifold to the air intake tube. It was my understanding that a catch can isn't required on the passenger side. The line that runs from the air intake to the passenger side valve cover is the engine's fresh air inlet. That is why you don't need to worry about putting a catch can or separator on the passenger side...it should actually just be filtered fresh air flowing into the passenger side valve cover. The PCV line that runs from the driver's side valve cover into either your supercharger inlet elbow or your plastic intake manifold if you aren't blown is the line that sucks harmful fumes out of the engine. That is the line that, if you don't have a catch can, and ESPECIALLY if you are boosted, sucks oil from the driver's side valve cover and deposits it into your intercooler, your throttle body, and can deposit on valves, foul spark plugs, and cause detonation (effectively lowering your fuel's octane).

I've checked my passenger side hose a couple times and it always seemed bone dry with no visible oil residue (compared to the drivers side anyways). I heard a few people who had catch cans on their passenger side say that the passenger side can barely caught anything; a few of those people actually removed their passenger side can because it didn't appear to be doing anything. But it sounds like a few people on this thread are catching oil on their passenger side so I guess it might be warranted?

very warranted if you are boosted.

Im running 20 psi with my drivers side vented to atmosphere and running DUAL catch cans off my passenger side in series.

Procharger actually calls for you to plug off the drivers side in the manual. I went with just venting it.

There seems to be a different way to run catch cans depending on who you talk to. I go off of my own results, by running it a certain way, then pulling off the intake and charge piping and inspecting everything to see if its working. That's how I found out that one can alone wasn't keeping up on the passenger side...for my application anyways.

Nice wright up Sally, thanks.
Isn't it if you're blown it goes on the passenger side and if not drivers side?

The passenger side is essential sucking in air, when you’re under boost it could actually be reversing the airflow and pushing crank vapours out that side (thus warranting a passenger side catch can). If you’re not blown, I would say there’s no need for a catch can on the passenger side.
If you cap off the driver’s side all together as the Procharger manual recommends, then I would expect a lot more vapours would be pushed out the passenger side. I agree with 07procharger about using the breather instead of capping it off. I think it’d be a little safer to vent that excess pressure somewhere, but I am not as familiar with how the crankcase venting works centri blowers.
It’s really a matter of preference, some do a catch can(s), some do two breathers then cap off the inlet on the throttle body and some do a hybrid system.
When I replaced the stock passenger side pcv hose when installing the blower there was no oil residue in it all. So I’d say if you not blown, do the drivers side and call’er a day. Just my 2 cents

id say hook it up the way its going to work the best for your application. What Is important is to check the system to make sure its working, just don't assume because you are draining oil that its working, a lot can still be getting past the catch can. Inspect all the piping downstream of the catch can periodicity to be sure.
