Looking at the M7 catch can or the ECS catch can. Anyone have an opinion on the best? Thanks.

 

I used a BSH on my R56. No complaints.

 

Our ECS system has a great design, but you will have to tap in your own hose connection. M7 is an exact fit but they use a mesh metal filter which works, just a simple way. We have not really put them up head to head to test. I dont think you can go wrong with either.
ECS one is Engineered and manufactured in the USA.

Unfortunately I won't be installing mine until next weekend, but I just got a cheapo from Amazon:


All aluminium, baffled, O-Ring seal for the canister itself, plus I prefer the dipstick to the sight tube, less places to have a vacuum leak.

 

I did the same. Got one on amazon. Have yet to install it but I’ve learned they all do the same **** lol. I’ve compared eBay ones with high end ones for my N54 cars and they basically a relabeled can lol

 

We offer several and the BSH is a complete kit

But with an R53 it is easy to just get a can and plumb it in, as I find the Mishimoto cans to be great.

Go cheap with some stainless steel scrubbers in there to act as a filter. Just make sure to install it correctly......NOT the way Alta or M7 say to.
Run the line from the passenger side valve cover line to the can and then reconnect it to the hard line under the IC. LEAVE the other side as it is.

 

I like the Saikou Michi dual can

 

BEST...best at what...?
It just holds blowby oil...how does one get the BEST oil container..?

When you go to the store, do you ask who has the BEST milk jug when you buy milk ?

Honestly, someone hasn't tried to install one on their mini nor has looked in the features. The SM can above has it all.

 

Pics of SM one on an r53? The above product is being shown as if made for r56.
