Where do I mount a Catch Can in my Genesis Sedan 3.8 engine bay?

[Jalvin Cohnson]

I am shopping around for a catch can, but I just noticed that the 3.8 Sedan has less space than the Coupe in the engine bay to mount the can. I don't want the can to be too far away from the PVC tubing, and I don't want to make any modifications to the stock air intake box, so I need help figuring out where I can mount the can.

Also, I was about to buy a Saiko Michi can, but they are bigger than I thought, so I am not sure if I should stick with that one, or buy a smaller one that is easier to fit in the engine bay.

Does anyone have pictures of their catch can mounted in their 3.8 Sedans? Any help is appreciated.

And put it here: (Didn't use the crap hose it came with and made my own aluminum bracket)

how easy is that to get to when it needs drained? also personally I prefer catch cans that you can see the fluid level so you can know when to drain them, in the winter they catch a lot of condensation and mine needed drained about every other week, although it is on the smaller size.

If you want to save a little money and you're a DIY kinda guy i did a write up on how to make a catch can from a water/air seperator, should be able to do everything for under $30-$40 bucks.

$10 catch can install

As mentioned by Jalvin, there isn't much room for mounting a catch can in the 3.8 sedan engine bay. The can I installed has a dipstick so you can check the level and empty the can as needed. One 10mm nut then remove the hoses to drain the can, takes 5 minutes . I spent about $35 on the above setup. The home made can looks like a pain to assemble and just as tight to install in the 3.8

Looking at my '13 3.8 Sedan engine bay, I'd venture the best place I see is the drivers side fender well, near the Oil dipstick.

The hoses really don't care how long they are as long as it's sealed. Admittedly, would be nice to be short-Er.

Looking at my '13 3.8 Sedan engine bay, I'd venture the best place I see is the right side fender well, near the Oil dipstick.

The hoses really don't care how long they are as long as it's sealed. Admittedly, would be nice to be short-Er.

I have found 3 decent spots that it can be installed in. One of them is where you mention, I was only worried about the length of the can. Some cans, like the Saiko I was going to buy, are almost 9" long, from the top of the in tube, to the bottom of the drain. I was looking at a Michimoto compact can which is only around 5" long. It will need to be emptied more often, but it would allow me to install the can in a spot that is really easy to empty.

Thanks brother! I am sure this will be helpful to a lot of 3.8 owners who are trying to stay under $50 for the mod.

haha. . .funny, I hadn't really noticed how little room there was in there. I'd done the Plugs, oil service,etc. It all looked nicely put together and easy. Then you began this thread and I thought, easy-peasy. . .until I looked. Not so much.

ETA: where are the other two spots you like or noticed?

I will try to remember to upload some pics of the 3 spots sometime this week. Catch Can took a backseat this week for me because I instead bought a Dip Your Car wheel kit to plasti dip my wheels black. Catch can will probably be my next project.

I looked at a few other spots but none of them allowed me to reach under the can and unscrew it without removing the whole thing. Also didn't want to drill into the car so opted for a spot that already had a stud sticking out that i could use.

Put mine in the exact spot. My hose was long enough that pressure warrants no need to use a mounting bracket. I bought this one(link below) and went to a local parts store to buy a 1 sided 90 degree 3/8s hose for 12 bucks.

But on my placement, I have a Ultra Racing Front strut bar installed, and was not really wanting to remove it. So mine was based on convenience. No need to even remove the engine cover (because I couldn't anyway).

Which model Genesis do you have? Could you show me a picture of the strut bar you mentioned and tell me about it? Any noticeable difference in performance? How easy was the install?

2012 Genesis Sedan 3.8

Very easy to install, only really need to jack the passenger side up, at least I did as my car is lowered with my struts.

It feels tighter on turns, but could be because I know it's there. I don't really push my car to the limits, really just wanted it just to burn some cash and for looks. I know that's not an expert opinion, but it's the truth for me.

I do plan on buying the whole set, again to be candid, just because. And I like having these things, because what else am I going to spend money on!

Man what is this? I bought a dip you car kit as well! Black Genesis, got the Brass Monkey Matte.

You and I need to stay connected on here. We have the same car and same year, so everything I do, you can, and vise versa. I am glad we linked up.

Thank you for the picture! I will look into the strut bar.

Also, I have another question:
What are the best websites you have found to have the most aftermarket parts for our sedans? I have been doing non stop research online and I always seem to find websites that have like 3-4 parts and that's it. I wish there was one website that sold all sedan aftermarket parts, but outside of Ebay, I haven't found much.

For my future mods:
1. Plasti dipping my wheels Matte Black tomorrow morning.
2. Just ordered a Michimoto Catch Can on amazon today.
3. I am going to wrap my hood with carbon fiber vynil.
4. I ordered a M&S black mesh grille to replace the stock one, which will look great with the black wheels and black hood.

Update:

I found a perfect spot to install Catch Cans in the 3.8 Sedans.

If you look in the picture, there is a nice spot by the oil dip stick, where you can mount an L bracket, then mount the can to it. All I needed is a 1/2" Fuel Hose, a 5/8" Fuel Hose that EITHER tapers to 1/2" on one end, or what I did, which was couple a 1/2" and 5/8" to recreate the stock tapered out from the PVC to the intake.

I bought this can:
Amazon.com: Mishimoto MMBCC-MSTWO-BK Compact Baffled Oil Catch Can, 2-Port, Black: Automotive

 

[Ozy44]

CATCH CAN UPDATE:
3,746 miles of mixed driving produced 60ml or about a 1/4 cup of blow-by pcv oil that would have been splattered and baked onto my intake valves had I not installed the catch can. My 2012 3.8 now has 75,648 miles on it.

Glad you posted. Just changed my oil over the weekend and blanked on dumping my catch can! 106000 miles for me.

2 Questions:
Jalvin: Can you empty your can easily without disassembly?
Everyone: Vented or closed and why?

 

[JgenG]

Do you know if there are any adverse effects of using a catch can with a bronze filter? do they increase crankcase pressure?
