    It's a good mod for direct injection only or forced induction neither of which the factory 2.5gen Tundra is. I've had many catch cans on vehicles. My Subaru WRXs caught a tiny amount not enough to be worth it or concerning, my 5.3L Chevys caught more than I could get rid of, like a full water bottle every 800 miles of crap. My Honda Civic Type-R and SI caught almost nothing. All of those vehicles were direct injection only. With the strictly port injection of the Tundra, the only real benefit might be a smidge of MPG and power. By smidge I mean seat of the pants feel from what I got in the worst case scenario Chevy trucks that still have their POS engines run 100k+ outside of the craptastic current gen.

    Not to mention most people get rid of their trucks before they can even tell if the catch can was a good investment. Granted for the price they cost, its not a big investment.

    Interesting. I ordered one this weekend and just got off the phone with JLT in Virginia... They told me they ad them in stock and could ship right away.

    Someone posted a picture of frothy yellow foam/gel on their oil cap.
    Researched it and determined it can come from the high pressure in the engine during combustion causes blow by gases and/or a faulty PCV. These gases are released by the valve cover to intake manifold thru the PCV. These gases are mostly water, alcohol(from ethanol) and oil. Not good - reduces oil viscosity, lowers octane and causes knock.
    "When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV "check" valve closes and, thus, this hose experiences no flow. Conversely, the PCV hose will experience "metered" vacuum when the engine is idling, low load cruising, and decelerating. This would normally draw unwanted crankcase vapor, unspent fuel, and oil sludge into the intake manifold immediately after a high load run." Radium website
    Youtube videos by Flatirons Tuning provide good information too.
    I am looking at and trying to decide between the Radium and the JLT.
    If I get the Radium 2 can system or 2 JLT cans, I might mount the PCV near the battery and the CCV on the passenger side firewall to cut down on the length of the hoses. Doesn't appear that the CCV can gets a lot of fluid. But I plan on adding or SABM modifying my intake so I figure it might help to prevent a MAF sensor code.
    Someone asked a question why the units are not mounted lower than the intakes they are returning to. Asked if oil/moisture would collect in the long hoses, cool and roll back into the PCV and CCV exit valves. Figure I will call JLT or Radium and see what their answer is to this question.

    I really looked into the Radium 2 catch can system. But after talking with JLT and some guys with supercharged units says they do not get anything on the CCV side I went with JLT. Also, the JLT team took a lot more time to go over and explain their product with me so I figured I would deal with them haha

    A dual can set up is purely unnecessary.
    A PCV can is redundant for your N/A motor, but you do actually benefit from it.
    You made a good choice.

    Here is a pic of my jlt catch can after about 500 miles. When I poured it out it was probably a teaspoon, looks like more in the pic tho. Good to know the can is doing its job.

    How much trouble would it be to install the single PCV version of the Radium can over on the battery side?

    Looking at pictures of the engine bay with it installed, it looks like it sits where the secondary intake tube runs for the Stillen CAI.

    I’ve been considering the JLT for the guaranteed Stillen compatibility but from the scattered posts I’ve been reading it’s been theorized that the Radium has a more elaborate baffle/filter system that would catch more oil that would otherwise be missed by some of the competing products. Not entirely sure if that’s significant enough to justify the pricetag but I’m a big believer in “buy once cry once”.

    Update: I have spent WAY too much time looking into this.

    Update 11/29/21

    I decided on the Radium system.
    Unfortunately Radium did not have a Black Friday sale.

    The final determination was for the Radium is a complete kit for the Tundra that requires not ANY extra parts.

    I found the Radium Tundra PCV and CCV kit on sale for $427.45 at 3 Stage Motorsports with free shipping.

    I found the 2 Radium Peacock drain kits for $28.45 each at FRSport.

    Also found several other companies that make the devices.
    Moroso has a good one along with a bunch of other companies.

    Summit Racing has A LOT of OTHER catch cans on their site that I did not research for this post.

    Original Post:
    I am looking at the Morosos, JLT and Radium brands.

    For me it is boiling down to how well they filter and baffle the oil and contaminants so that only filtered air is returning to my engine and that it has a drain.

    Moroso $188.90
    [​IMG]


    $164.90
    [​IMG]


    $162.90
    [​IMG]

    The JLT has a fine mesh stainless steel filter and a honey comb screen. $159.00
    [​IMG]
    "Filtering consists of a fine mesh stainless steel screen that traps fine oil vapors and releases them once heavy enough to fall. They then pass through a 1/2" thick 1/16th" aluminum honeycomb filter where they grow every larger and then fall into the bottom. By the time the oil gets through the filter it's too heavy to be passed on into the intake."

    No description/rating of filter efficiency.

    The JLT 3105D is $159.00 for the Tundra kit. I do not see a peacock drain available and did not see a drain port in photos or any videos.
    They do have a 3.0 Oil Can extension that turns it into a 6 oz. unit for $39.00.

    The Radium has a stainless steel medium as their filter. Looks kind of like "steel wool" type filter on some model and a screen on others. No description/rating of filter efficiency. The Radium dual can (CCV and PCV) Tundra kit is $449.95. Single can is $254.95. Peacock drain kit is $29.95.
    [​IMG]




    I still plan to get one for the PCV side and one for the CCV side. Going to mount one like the JLT by the battery for the PCV side. The other is going on the firewall by the CCV vent to cut down on lengthy hoses. I may get a 9 oz. can for the PCV side and a 7.5 oz. can for the CCV side.

    People say you don't need one of the CCV side. But I keep seeing posts of people having air flow sensor issues and dirty intakes and needing to have their throttle bodies cleaned. Figure it might cut down of these issues. Just seems that if you are using clean air filters in your intake you should not have dirt in these areas. So if it is coming into the closed system this seems to be the only source of the dirt and contaminates. So I will try it out and let you know if it works for these issues.

    Radium sells this filter and has directions for using it to stop any air flow back into the engine. But it does produce vapors and is not the "best" for the environment.
    Filter attaches to the exit port of the Oil Can.
    [​IMG]
    From Radium website:

    Shown below is an open system using a catch can on each line. For this system to work properly, some customization must be done. First, the port on the intake pipe that was connecting to the crankcase vent line must be capped. The same goes for the port on the intake manifold for the PCV line. Furthermore, the PCV valve should be removed and replaced with a large diameter straight-through fitting. This may require some modification to the valve cover or creation of a special fitting depending on the vehicle.

    (NOTE: Eliminating the PCV valve and the corresponding connection to the intake manifold will remove the ability of the PCV system draw out moisture from the crankcase.)

    This system essentially creates two large, high-flowing ventilation points through which the crankcase can breathe.

    Radium Engineering offers optional breather filters that install on the outlet port of the catch can. They can be found HERE.
    Note: There may be "smells" coming from the catch cans and entering the engine bay. These "smells" can make their way into the fresh air intake of the HVAC system and can be noticeable inside the cabin.
    [​IMG]
    Wonder if you could put a hose on the outlet and run it past the area the cabin air intakes in thru the firewall. Could run the hose past this area and then put the filter on it or not use a filter at all. I would use a filter because we have these "Dirt Doobers" - flying wasp like creatures that love to build mud nests in narrow tubes and crevices.

    Have you looked at RX Performance? (RXP) They sorta wrote the book on catch cans.
    After lots of my own research I talked to James (owner) and settled on their system. It works very well and I dump 2-3oz of shit jizz every time I empty it. I drain and clean it every oil change (5kmiles). I am SC'd too.

    Ugh, another thing to spend $$ on .

    So if going with one catch can, which is better for N/A trucks?

    The Radium system, and all modern catch cans are sealed systems. I have a Ford performance catch can on my 2020 Bullitt, as it has DI (and PI).

    I like the idea of the dual, and may just do it and cringe... LoL. I'm going to be towing alot the next few years, and plan to keep my truck 10+ more years. Currently have 60K.
