Oil Catch Can Install Guide

They exist. I had to do this on my Polaris Ranger. I have the diesel Ranger and put a turbo on it. The engine routes it's crankcase vent out to the intake and the turbo kit runs it to a fitting in the intake tract of the turbo. I put an ADD W1 catch can in it and used a barb to barb brass fitting to mate two hose sizes.

Just search something like 3/8 barb to 1/2 barb.

 

So the catch can I'm buying doesn't include hoses. Uses 3/4 hose barbs. Do I need any specific kind of hosing?

 

Truck hoses are 3/8.

 

I use 3/8 fuel line, the vacuum line from auto parts store was too weak and collapsed easily under vacuum. Fuel line is much thicker and I have never seen it collapse under vacuum

 

Is there any need for these on a non turbo engine?

 

Sub'd to hear about non-forced induction benefits.

 

“Need”? No. But definitely a benefit for your engine. It will help your top end internals stay cleaner longer by in essence adding a “filter” to the PCV system. An ounce of prevention and all that. If you’ve ever seen a 300k mile plus engine apart and how nasty they get inside, this will minimize a lot of that build up. While many engines run to that mileage without a catch can, you’re giving yourself more time by adding one.

 

It also moves me closer to to having a supercharger ready platform!

Another question. Another question. I'm going to put a Pelfreybuilt aux fuse panel in. It appears that the traditional mounting point for this would be blocked by the panel. Is there another handy place that doesn't require drilling / adaptation?

 

If you go back in the thread there’s a couple options but really you can mount it anywhere you want. There’s only a few considerations to keep in mind:
First and foremost you want it to be accessible. There’s no point in adding the can if you can’t get to it to actually empty it out.
Secondly, the optimum place would keep the can as close to the original inlet/outlet as possible. The shorter the run, the less stress you’re putting on the vacuum lines. Think about drinking liquid from a very long straw versus a short straw.
Lastly you’ll want to avoid and hard turns in the line when you install the can. This kind of goes in line with the above but for another reason: the can works by creating a condensation point for the PCV vapors that then drip into the can itself to be collected. That being said, if you use right angle fittings or have otherwise tight bends in your hoses, you’re adding a place where the vapor can collect and condense.

It’s tight in the engine bay but there are still a few options where to mount if you’re creative enough.

Good luck.

 

Like Ghost Ship said, mount it close. Preferably keep the can lower than the PCV. You're going to get some condensation in the lines no matter what you do. Having the can inlet lower than the PCV valve lets any condensate flow to the can. Flowing from the can up to the manifold isn't a big issue, there should be less vapor at that point, plus any condensate you do have would drain back to the can.

For what it's worth, in my Tacoma the can is about halfway between the PCV and the manifold measuring vertically. I collect a tablespoon or two every tank of fuel and the line to the can from the PCV will have a little residue in it with a little pooling near the end of the run at the PCV if you disconnect the line. I've only done this once when changing the PCV valve. What pools up after shutdown is cleared the next run.

 

Is there a preferred brand?

 

Slick set up. Any details on how its mounted?

 

I've got the ADDW1 non vented can on my Tacoma. A threaded captive nut on the drivers side fender provides a good place to mount it using the attachment point provided. You can put some steel wool (I've used stainless before but now use copper) in a threaded chamber in the can to give the vapors more area to condense on. If you do this you'll need to change it out every once in a while too. To drain it you have to unscrew the can and dump the contents. I go over my Tacoma once a week, typically Saturday, since its my daily driver checking oil, tires, etc. I dump the can once a week, it has a couple tablespoons of fuel/oil/water condensate in it. If something comes up you can miss a week or two without problems. Some members go lots longer!

On my BRZ I have a Moroso can with a drain port. This is a good can with lots of good material in it. I don't drive my BRZ much but check it when I do a check before going out. I've got a couple tablespoons out after waiting a few hundred miles to check it. Your name suggests you have an FRS. If you do, the Moroso can is mounted on the passenger side strut tower bar that is tied to the middle of the firewall. The PCV valve is on the top of the engine at the rear, easy to find and connect to. I bought this can as it can easily handle boost if I ever decide to go that route. Even then I'll have another check in the line ahead of the catch can. If I supercharge the BRZ, I'll also add a can to the crankcase vent from the other side of the engine.

I put an ADD-W1 on my 2013 Tacoma 4.0, and I just ordered another one to go on my Wife's 2017 4 Runner Limited. They work great.

 

Back in the day I used to race a FSR Comp mountain bike. I accidentally transposed a letter when I made this title for a MB forum at that time, but the name stuck. These days I stick to KTMs rather than pedals. Maybe I should update that?! My twitter handle is Semifamous Dave. Can I change my name without loosing all my old posts and what not?

 

Light bar mount. Unbolted the bolt that holds the intake brace on and used it as the location. Works really well since the PCv lines are right there

 

So kind of an old thread, but I just ordered an ADD W1 catch can and I think I understand about everything with the install and function except one thing. Do you have to add oil inbetween changes since this is removing a small amount of oil from the system?

 

No, I never add. The stuff you get out is a mixture of oil and fuel vapors and water. You lose a bit of oil but not enough to worry about at least on a healthy engine.

Look at it like this, before you added the catch can, the engine was taking in the same mixture and burning it. You just didn't know what and how much it was.

Just check your oil level like normal and add accordingly.

 

Thank you for the info!

 

The inlet hose should be oil or trany hose, or, at the very least, PCV rated. Otherwise the oil going through it will eventually degrade the hose from the inside out.

The $70 ADD-W1 cans look identical to the $35 Ruien cans on Amazon. I'm ordering a Ruien can for my daughter's Corolla.

I paid a little more for a Saikou Michi can for my Taco but haven't installed it yet. http://www.saikoumichi.com/s1_oil_catch_can.html
