MOROSO CATCH CAN INSTALL 2019 TRD OR

Hello all!

I installed a Moroso oil/air separator (catch can) on my 2019 Tacoma TRD OR – 2GR-FKS 3.5L V6. This can has been used on two of my previous vehicles with very good results. 2016 Honda Fit EX and 2007 Tacoma SR5 2.7L. It has removed oil/fuel vapor/moisture in both vehicles that otherwise would have been ingested into the intake track and onto the intake valves. I check and empty it every 500-1000 miles. It definitely works! Whether you are yay or nay regarding catch cans, here is the fairly simple install procedure.

Materials:

Moroso Universal Black Anodized 85497 Air/Oil Separator (purchased from summitracing.com)
The kit includes 3’ of 3/8” PCV hose. I preferred using higher quality/better flexibility Continental PCV hose from Amazon. It includes 4 smooth back hose clamps for use on the engine side only. The 90 degree barbed hose fittings mount very tightly into the hose on the can side – no clamps are needed. Lubricating the inside of the hose and barb exterior with silicone spray makes the process much easier.

All materials below purchased at Ace Hardware:

¼” x 1” x 4’ Aluminum Flat Bar
Length: 5” inside bar (fender attachment) 9” outside bar (can attachment)
Use two existing 8mm threaded fittings on fender wall to mount.
Drill aluminum bars & outer steel can mounting bracket holes with 5/16” bit.

(2) 8mm x 30mm 1.25 pitch stainless button head socket cap screw
(Aluminum bar to fender wall)

(1) 8mm x 20mm 1.25 pitch stainless button head socket cap screw
(Aluminum bar to can mount/cap head facing fender wall)

(1) 8mm 1.25 pitch stainless stop nut (nylon insert)
(Aluminum bar to can mount)

(4) 8mm stainless flat washers

(2) 1.5” rubber washers (aluminum bar to fender wall)

Have fun and let's go places!

Not sold on the "benefits" of a catch can but it looks cool.

 

I’m with you on this one. Maybe if it was some high horsepower engine maybe it would have a place but to me doing this is like putting drag radials on a stock minivan lol. Too each there own though.

 

Wondering what a dealer would think about a catch can, seems like the ammo they would want to void a claim. Anyone got any experience with catch cans and warranty issues?

 

In Fords eco boost engines carbon buildup on the backs of the intake valves from recirculating emissions is caused by direct fuel injection as no fuel is washing over the backs of the valves. Port fuel injection sees fuel from the injectors wash the backs of the intake valves, so they stay clean, or cleaner than direct injection which affords no cleaning. In the case of the 3.5 6 cylinder in the Tacoma’s 3rd gens, there is both types of fuel injection, but it remains to be seen if the port injection, as only one half of the fuel being introduced, is enough to keep the back of the intake valves clean. An oil separator guarantees the reduction/ removal of the oil in the recirculated intake air, but may not be necessary and may come with warranty issues.

 

Please show me one document customer case of a 2.7 or 3.5 Ecoboost with this problem. Not someone saying it can happen but someone it happened to (people selling them don't count). I'll wait.

 

not the first time i heard about the dirty valves and direct injection in the ecoboost

 

Yep they work @state48overland and I hooked it up on my 19' after 500 miles I check it every so often. Forgot the brand name but it came local here from Tucson and he has them on the website I believe. Dont care what anyone says it's just more peace of mind for me. And easy to take off if any warranty issue came about

I come from high hp cars so always been about it

 

It would take quite a bit of time to search again through the multiple youtube videos identifying this problem, which is one of the reasons Toyota elected to use Port injection for at least part of the fueling of the 3.5 including in the Tacoma. There is a ford mechanic who identifies this in a youtube, and many youtube videos by auto industry engine experts who support this opinion and it makes sense that this can/does occur. Obviously I have no ecoboost engine intakes or carbon valve stems to show you, but it's a common opinion and images of this problem are shown on sites/videos in any number of locations on the web. Not looking for an argument, just sharing info. If anyone wants to hedge their bets against this problem, a catch can/oil separator is identified to help reduce or eliminate this problem regardless of the engine's manufacturer, Ford, Toyota, any of them that use direct injection solely or in part. There are many oil separators for the 3.5 liter that require no little or no extensive mechanical knowledge to install them that work.

 

I mean, like, here's a thread talking about it?

https://www.f150ecoboost.net/threads/ecoboost-sludge-build-up-on-intake-vavles-possible-fix.5849/

It is super common in the DI Subaru world and leads to recommendations like walnut blasting intervals. I was excited to find out the Tacoma uses the D4S with a cleaning function.

Also coming from higher HP stuff, I run them there...but don't imagine I'll put one on the Tacoma. However, if it is worth it to you, run it. Cheap peace of mind to let you sleep at night is great.

 

Correct a thread saying it could be a problem (that pic is not from an ecoboost) but nobody in the thread actually had the problem. I know it has been an issue in other early DI only engines but Ford and most others have figured it out. Ford actually has a patent on a way to clean the backside of the valves with fuel on DI only motors.

Catch cans have their place and I have one on my supercharged Cobra. I run it to keep my intercooler clean though and not the intake valves. Ecoboosts did/do have some well documented issues just carbon build up is not one of them. That's all I'm saying...

 

Yeah, it's a common opinion that it will happen yet there is now well documented cases of it happening. Took a look on the F150 forums and you'll see well documented cases of timing component issues, leaking oil pans, new 5.0s drinking oil, etc. but no carbon issues.

And the Ford mechanic you're quoting is a selling catch cans... wonder why he recommends them? I've been down this road. I had 3.5 ecoboost before my Tacoma and was set on getting a catch can because of everyone saying it will be an issue. When it cames down to you wont find anyone really having the issue.

 

Adding a AOS to the 2GR-FKS particularly a decent capacity one placed in front of the engine will help dramatically if you Offroad and do any steep inclines.

 

You wouldn't have any information on where to purchase this particular can would you?

 

i can ask, they seemed to removed them off their website. not sure if they are producing them anymore

 

Carbon issues on DI engines are a thing. The FKS uses Toyotas proven 4DS system which makes it not a thing. In this application, a catch can is not needed.

 

Update: Yes – 2GR-FKS is direct and port injected. Catch can certainly can't hurt, eh? Drain interval is now 3K miles. At that interval, 22ML or bit more than a generous tablespoon of oil and other nasty muck is consistently captured by the can.
I don't want that gooping up the intake manifold or valves, even though they are washed somewhat by the port injectors. How much oil will be injested over the service life of the engine? Do the math.
Don't install one if it's not a concern. In other words...don't worry...be happy
