I'm just bummed. I thought I made a pretty good joke on page 1, but after 4 more page...nothing.

One of our cars has the standard EE-can, and it does great. I think we get about a tea spoon to table spoon out every oil change (which is probably about every 700-miles). I just pulled the lid off, and it was pretty dang clean, like seen in the video. There was little to no puddling anywhere.

I think any and all these cans are worth at least something. That MM might be better for bigger power cars, but I think I have what suits my build and plans.

the MM just seems illegal with a vent to atmos on road or on a track. id be shocked if it passed race inspection. the other looking sealed up just seems better.

When excess pressure builds in the crankcase, it has to go somewhere, the crank front main seal can potentially blow out under high boost applications, so the breather helps prevent this. On a stock vehicle, it may not be needed but when you start raising the boost, a breather should be a necessity. The MM catch can doesn't vent all the time, the one way check valve prevents that. It only vents when there's any excess crankcase pressure. The filter stops any oil residue from escaping only allowing the excess air to vent. its a very smart design which incorporates two valuable pieces of equipment in in one.

I understand how it works, but could still be a reason for denial of a warranty claim with a stock car.

Elite filters and vents back to the intake (closed loop) which is how most catch can systems work

Extremely well documented problem with DI engines. Savagegeese (and others) have videos on it

I’ve seen GM deny claims with a closed loop can too. So toss that argument out. I have a friend now that’s facing this problem. Stock with catch can, I believe it’s a Tracey Lewis can. He’s got very low compression on cyl 5 and they are blaming the catch can.

“ Tampering with emission systems causing a rise in crankcase pressure” Basically blaming it for damaging the ring pack. So now he’s fighting with corporate on it.

He should of took it off yes, but point here is even for dumb stuff like this they can deny a claim. So now his attorney has written in asking to show proof how this damaged his ring seal(s).

Burden is on them.

Crazy - vents to intake and it's a relatively low air flow

[Evansa22]

The MM also vents back to the intake tract. Its only when pressure exceeds the check valve on the breather that it vents to atmosphere. With the road course top their is no breather on top, just a hose that comes off that position which can be routed to a location of your choosing. Just for clarification

My mighty mouse wild gets a lot more than a tablespoon, but I drain it at every 3k mile oil change. It's about 2-3 ounces. My blower is dry, no oil pudddling. Again, I'm not proclaiming one to be better than another unlike most Elite owners. I'm sure both do their job, the built in breather is just a bonus.

+1 I get a close to an oz every 3-4k miles, def more than a tablespoon

That's the one thing, in my curiosity, that seems like it could be a very small liability, but probably easily defeat-able, IF it has any merit. I get the venting, and that makes sense, and seems great. But what about the vapor from the venting? I'm, honestly, asking if there's any problem with it dripping or the vapor leading the oily film where it shouldn't be? I could easily see zip-tie'ing a small rag around the filter if I were that concerned, but I'm just wondering for anyone with one that might be willing to add to conversation.

I don't really like the idea of venting to atmosphere, and the emissions-part of that, but I'm less concerned about that (and what little, if any, impact it honestly might have) than the benefit of relieving crankcase pressure. I'm seeing 15-16-lbs of boost (not making power a lot of you are making at that level with H/C/LTs/etc.), but boost is boost, and pressure is pressure, so I'm kinda' wondering if I might want to jump ship and try a MM.

And for clarification - I stated MAYBE 700-miles between oil changes. If I changed at 3K-miles, it would, obviously, be more

I thought the same thing. But someone here mentioned the Metco Valve Cover Breather. I kept my installed CC and added the breather. That seems more practical than replacing your CC.

Ps. Just ship it to me and I'll forward it to you

MM sells a sock that goes over the filter.
I never had oil residue around it.



If you don't like the venting to atmosphere part, you could upgrade to their fitting top conversion. And route that hose to the oem air filter box. I did that before I switched to the wild kit.

AH!!! Sweet!!! Thanks for the info!

[Joshinator99]

I’ve been running my MM Wild for 2 years with many dyno pulls and drag strips runs. I’ve never had any oil residue in my engine bay at all. It’s spotless.
