I'm assembling all the parts to install an oil catch can on my 2010 MCS Clubman. I've watched many vids on youtube on how to do it. One method was to cut the crank case breather hose (?) and connect a separate hose to it from the occ. And I see some where you connect just two hoses directly from the occ to the valve cover and where you removed the breather hose. I don't feel comfortable with the first method cutting this hose. What if the connections don't fit? But looking into the 2nd method, where do you get those adapters to connect the hose to the valve cover and breather hose? Sorry if I'm not using the correct terms for these parts. my occ did not come with the adapters like the ones in the vids did.
Also I'm seeing 2 different opinions on a pcv delete, one says its a must if you have a occ and one says don't do it, it'll be too much pressure build up and it will blow the gaskets.
Thanks for your advice.

 

You can get the adapters from M7Tuning separately. Watch their vid.

DIY OCC for under 50 bucks. DONT empty into solo cup, that’s why it red, gas eating cup. First empty after 2000 miles. Recommend check way more than that. I’m going to do it every fill up since I’m checking oil anyway. 140,000 on odu

 

only 2 videos needed and one of them has all the parts listed off of amazon.

Im with Islandguy here. The turbo inlet side is easy as it is a rubber hose. The rear pcv hose is actually plastic inside and I am not sure how to seal it once cut. I think this is his question.
I decided not to install any for this reason. I am not convinced that the turbo side was that important, as opposed to the rear one.

You deleted the hose completely on the rear with these...https://www.ecstuning.com/Checkout/?...srep=jcrabtree Buy 2 of them and boom no more oil into intake. 2000 miles no cel and I’m at 140,000. Watch this vid.

 

I have considered that, but not 100% convinced that it is a good idea as of yet.

It didn’t even notice that it was done. I know I’ve only had it for 3 months, but there are plenty of threads about it, and with a OCC in place you got nothing to lose other than the 20 bucks and the time to do it. It took me under 30 min to delete it. Flat head and a T25 only things needed. If you break your hose I’ll send you mine for cost of shipping.

 

I guess I was a bit vague. I am not sure if blocking off the rear is a good idea. The designers wouldn’t add a line (cost) instead of sealing it off originally unless it had a benefit. I am not sure the exact purpose of both vents are honestly.

if I’m not mistaken that’s is one of the design changes on the n18 to help with carbon build up on the intake valves. And those plugs are mini parts btw they knew of issue.

 

Good information on the install.

 

On the fence about one or two cans. Lines are under vacuum and if you don’t clamp up the hoses or your budget can doesn’t hold seal, look out. The other option is air/oil separator. Other option is engine with dual port/direct injection.
