That's what I tell my wife when I gas the car every now and again. I'm getting rid of the carbon build up

Ok back on topic here. What about water/meth injection for constant cleaning of the intake runners/valves in addition to a catch can or AOS? Would that work?

I started a thread on this. If you want to resurrect it, I wouldn't be opposed to discussing this idea there.

Default SOA - Mish oil cans and warranty

I will call SOA in next few days about warranty and Mishi oil cans - I cant imagine this would void warranty - I will find out and post. I am new to Subaru - first on / so I will do my research and report back unless someone out there already has done so - Im calling tomorrow.

I'm very interested in the warranty voidance/lack of voidance from a catch can. I'm not really trying to shell out $500 for some fancy brackets and 2 cans, but the fact that it's all comprehensive, clean, and direct fit seems legit enough to make me comfortable if I do spend it.

When you call SoA please don't ask specifically about THIS can, ask in general, and see if there's any difference with a quality name brand like Mishi vs a DIY job.

Except that really doesn't apply to carbon buildup in a DI engine. Carbon buildup is on the intake valve, not the exhaust valves, rings, or piston like a non-DI engine.

Doesn't matter, anything they TELL you is pointless. You need it in writing that the catch can will not affect (notice, no mention of void) warranty coverage in any way. I can say with 99.9% certainty SOA will not give you that in writing. As far as splitting hairs of terms, they can tell you it won't void warranty coverage, but in reality any engine/powertrain coverage will be DENIED coverage on your still valid warranty.

The clamps included are of high quality. If you insist on sourcing your own, our clamps secure a range of 16mm-25mm.

Thanks

The vent shoots oil out and I go through oil very regularly (started my car one day and the oil pressure light came on, almost drove it dry, been checking oil a lot more regularly and bought a oil pressure gauge, just needs to be installed). If I bought an oil catch can would that take the oil from the vent line and put it back into the oil pan? I tried to make as much sense as possible but I don't really know what I'm talking about. Thanks in advance.
Adding a catch can is a great way to prevent oil and fuel byproduct from negatively impacting your intake tract and valves. Check out our writeup at the link below for more information.

Thanks!

Looks interesting. I will finish breaking in my motor and consider this as an option.

At 5,000 mile service I checked both catch cans. After 4000 miles with catch-cans installed there was an estimated Tablespoon of "blow-by" of oil caught in these cans. Anybody else having same results?

Noticed about that same amount, but that was after only a dyno session and a few weekends of VERY hard driving. Our can design is a bit different than the dual can though.

babying the car or running it hard wont do jack for a direct injected engine. There is no way to "burn off the carbon" that gets deposited on the valves -- valves that in a regular fuel injected engine get continually sprayed with gasoline which helps to clean them.

The catch can should remove some of the oil residue and moisture being vented from the engine and recirculated past (behind) those valves - where fuel never goes - recirculated because those crankcase emissions cannot be vented legally into the atmosphere.

+1 for SOA answer on warranty work, specifically getting it in writing. I would love to read an official confirmation of this not affecting warranty.

No 100% response from SOA - dealership was not very decisive either - they made it sound like any alteration could alter warranty...

Typically when you ask people about something they don't know anything about nor understand, but know it's being installed by an end user - not a professional... You'll always get vague answers. Nobody is going to give you their word and everyone will be hesitant.

Chances are if you have an oil related issue with your engine and they pull the catch cans to find they're full, you'll be out of luck.

However if you come in with a jacked up cam gear sensor, they're probably not likely to deny the claim.

Just chiming in here to let everyone know our installation guide for the Mishimoto catch can system is now up! Sorry for the delay in getting this out to everyone!

Or you could save yourself a few hundred dollars....

http://www.subaruforester.org/vbulle...nstall-426265/

And before you start flaming, NO, the can is not in contact with the ECU wiring loom.

Not intending to be disrespectful to Mishimoto in any way. I love your products but by the time they land here in Australia $500US works out to over $700AU. This whole setup cost less than $150 to install.

Default 2015 WRX catch can

Yes, the mishimoto is a bit pricey but the setup is top notch. A friend purchased an off brand model that felt hollow and cheap for his speed3. You really can't compare the quality amongst anything out there. Remember this set up offers you two cans and really nice hose kit. My only complaint is ease of draining. The cans need to be unscrewed and then taken apart to drain. I find it difficult to get my hand in the tight spaces where mounted. It would be nice if they would install drains on the bottom of the cans with tubes. Honestly, it takes minimal time to remove them and I would purchase again. If price is a concern look out for sales, I've seen them a good deal less than the advertised price.

Thanks for the kind words regarding our kit! Thanks for the feedback regarding the draining of fluid. We are actually working on a drain-valve which would thread into the port on the base of our can. This may be offered as an add-on item in the near future. This would certainly make draining a bit quicker and cleaner.

For those with concerns regarding pricing. Be sure you check with our vendors for this kit, they will have the best available pricing on all of our products.

Thanks

Got around to installing my Mishimoto catch cans last night, ended up following the install video Mishi provided after taking a look at install guides online. Quality on the catch cans is great and the fitment is perfect. Couple of things that I noticed

One of the holes for the passenger side catch can mount on my WRX chassis is not threaded. Mishi provides two 10mm bolts, I was able to secure one side where the intake box is mounted but the other I ended up just using a zip tie. Will most likely source a nut and bolt for a more secure fit.

Removing the catch cans looks to be a little difficult due to placement, a drain valve would be much appreciated. I attempted to unscrew the catch cans after performing the install and didn't have enough energy to do it from where they were mounted.

The driver side catch can has a hose that sort of blocks the oil fill cap. A minor annoyance but in my opinion if the catch can were shifted back an inch or so it would have resolved this issue.

Installation took a few hours with some breaks in between, this was my first time pulling anything apart in the engine bay so I was cross referencing the video a lot to make sure I was attaching the hoses to the right parts. My hands and arms are rather large so working in the tight spaces was a little difficult but manageable. Would highly recommend mechanic gloves as there are some places where you can scrape your hands. I didn't remove the bottom tray of the car and did remove the serpentine belt to be able to move the AC compressor easier.

Thanks for the feedback from your installation! Great to hear you found the components to be of high quality. Sorry you had issues with mounting the passenger side bracket. The front hole should be threaded and reuses the factory bolt for the airbox. We include a nut and bolt for the rear mounting hole. Was this included in your package?

We actually just released a drain valve system specifically for the catch cans included in this kit. Check it out below!




Looking forward to your response!

Thanks again!
-John

Don't recall seeing a nut for the passenger side rear mount, there were two 10mm bolts of different length. I'll double check my work area to see if I missed it.

The stock tune uses cam phasing as internal egr. It opens the intake valve early and exhaust gases backflow into the intake to re-burn HC and reduce NOx. This happens under light load/partial throttle or what I would call "babying your car"
