OK, sorry for the dead thread bump.

I recently installed a BSH OCC and a BSH Dual port boost tap. The way I am reading this and please correct me if I am wrong is to put the Dual Port in with the block off plate and route the OCC as ususal?

 

Yes.

 

I've just been through the entire thread and am still a bit confused. I just had the walnut blasting done, car is running great. To help avoid this confusion I should buy the two block off plates AND an OCC?

 

Yes. Or two cans

 

Do you have anymore? If so how much to ship to 95125?

 

I do indeed, however there really is no need to purchase them from me anymore, simply call into your local MINI dealership and ask for the blanking cap, part number 11617596034 this is exactly the same as I supply, also it's exactly the same blanking cap which you can purchase from Peugeot, Citroen or Audi.

 

To the people that have been running this setup for longer (Blocking the rear PCV):

1) Do you guys unblock the rear PCV for track use?

2) Any issues have been reported in the long run because of any supposedly increase in crankcase pressure?

I believe some of you may have up to 2 years using this set up. So its effectiveness could be proved I supposed.

Any info is much appreciated, thanks!

 

I've had my rear PCV blocked off for about 2 years with a catch can in the front PCV, and now 3 additional months without a catch can in the front PCV.

I don't track the car but try to keep the RPMs in the 3-4K range to hopefully lessen carbon buildup. I also drive the car pretty hard and redline at least once a day.

Car has 36k miles, I blocked off the rear PCV at about 13k miles. No problems to report.

 

Alternately you could get the can, which has a two stage filtration system, from MC2 and which installs directly to the valve cover and hose on the driver's side. No need for blanking caps or the BSH boost tap.

 

I was using the block off and while on track the dip stick blew out and oil spewed everywhere. My car is running extra boost. I always remove the little blocker for race/track days. Not happened since.

 

Is this post dead?
Has anyone actually addressed how the oil separator in the VC works?
It seems their is a valve in the OS that needs/uses vacuum to pull the plunger in the OS up to allow cc gases to pass through. Really vague on its operation. I'm not sure but the Shop Foreman from local Mini dealer is gonna advise me exactly how it works.
I think you attach both PCV vent lines to VC and "T" them together into OCC on only ONE side. Then u run a small amount of vacuum to the other outlet on the OCC to another OCC on the vacuum side for additional oil separating action. This way u have the original vacuum as designed by very bright engineers but you have triple oil separating going on via the 2 OCC and the original OS in the valve cover. You get proper CC venting, proper3 way oil sep action and do not vent to atmosphere.

 

Hahaha. No, just no. We know how it works that has been posted many times

 

New to this thread, but I am considering the PCV delete as I just got my 2010 Clubman S back from dealer for carbon blasting and other things. The car has 45k on it, and I've been running a tune with increased boost fairly regularly for the last two years. More recently I experimented briefly with the PCV delete for about 5 days, then backed off thinking I'd do it after the carbon blasting. Anyway, the dealer did the carbon blasting, and fixed the timing chain, but also found and fixed a coolant leak at the thermostat housing, a valve cover leaking at the PCV diaphram. (Intake tract covered in oil) and finally an oil leak from the turbo supply line fitting. So my question is, can any of this be related to my brief experiment with the PCV delete, or the increased boost? Or is this just a run of typical Mini S problems?

No, I ran the PCV delete with catch can for over 2 years in my clubman and never had any of your issues. I was running a high boost tune and meth injection.

 

Tx Killerfox. That's good to hear. I assume you took it off because you sold the mini?

 

yes, I sold the mini.

 

Also...did you think the CC and delete really worked to keep off the carbon?

 

What is the extra outlet nexy to the crank breather off the manifold?
It appears to be blocked off.
Does anyone know
C above pic. It's the open port so to speak.

 

Old thread but I'm here to report Unequivocally that although you run a crank case delete system, carbon or more accurately "coke" still builds up on the back of the intake valves (did not inspect exhaust valves). In this case only 8k miles. Without the benefit of fuel washing over the valves, this issue will always persist. A meth system would help greatly. Or in another words; DI kinda sucks!!!

 

I got the blanking caps at the local Mini dealer. Had to struggle with the parts guy because he was questioning my motives for looking up the blanking caps with his drawings. Got through with it after explaining numerous time my intentions. Had to have him pull the drawings for a N18 motor intake throttle body. And the part on the drawing is number 12. Ordered the 2 and they were 5.88 each. Also, have BSH catch can on the way. Can't wait to install.

 

Bump.

Anyone still running the pass side pcv delete? Any long term effects?

 

My passenger side PCV had been blocked off for seven years and I have had no problems.

 

Rather than use a CC could one just run a long hose down to the bottom of the car? Thats a pretty common mod on DI diesel trucks...

 

That's called a draft tube, it was common on cars before pollution controls.
They were designed to protrude down into the air stream under the car so that the venturi effect would produce a vacuum to draw out crankcase fumes. That slight negative pressure is important for crankcase sacvenging.

 

No not exactly a downdraft, i mean just to drain the oil drips to the ground instead of into a CC. Thats a mod that a TON of ford powerstroke owners make to keep oil out of the intake system. You run the tube up (to avoid the downdraft effect) and then down below the level of the engine. Environmentally friendly no, but when you drive a diesel truck thats not really a concern for most Folks.
