So last weekend I installed the BSH catch can (OCC) and so far after this week of heavy driving the can is still absolutely bone dry.

I know I should probably wait a bit longer but I took a flashlight to look inside and there wasn't even a spec of oil or sludge or residue of any kind, just a nice shiny oil catch can.

Maybe I installed it wrong or maybe i'm not waiting long enough, who knows? Hopefully someone here.

I've heard only great things on here and other forums about these catch cans but so far I feel like I just wasted close to $200 on extra tubing.

I should also note that when I had my HPFP and fuel rail replaced four thousand miles ago I was told that I had massive carbon deposits. So if you take MINI of Dallas' word for it then this thing should be catching at the very least something, right? Any suggestions here would be a huge help or at least ease my mind a bit that I didn't just throw a bunch of money out the window.

I've attached two photos, one of the setup (I know I haven't gotten the other hose clamp yet) and the other is the dip stick, and that is obviously without it being wiped beforehand.

 

I think that you need to wait a little longer. After I installed my catch can and direct dual boost tap I waited about a month and got the results you see in the picture attached. Also, do you have the direct dual boost tap? Because if you don't the can will not catch as much.

 

No, I don't have the direct duel boost tap because I don't really have any need for it, so I thought. I was under the impression that it would only be needed if I was going to actually tap into it as a source for a boost gauge or whatever. I mean I'm still not totally sure what it does to improve the OCC. If the duel boost port is necessary for the OCC to operate properly then why isn't it sold as a package?

 

Try connecting it up to the other side(the vent into the intake manifold) and you'll have some oil in that can in no time.

 

Why don't they include the direct dual boost tap? That is a good question and one that i do not know. To answer your question, technically you should be running two catch cans, one where you have it now and one where oxybluecoop was talking about(vent into the intake manifold). The direct dual boost tap blocks off the intake manifold side that it forces everything through the one catch can eliminating your need to run two catch cans.

 

Side note MDL...how did you mount it with the alarm switch still in place? I've wanted one of the cans, but I have the factory alarm too. I didn't think there was a solution to this yet...

 

I have the factory alarm so I bought a bracket(basically the same one that comes with the BSH OCC) from BSH and just drilled a hole in the bulkhead. I would like to know how the OP did it though.

 

You can see some more pics of the install at this thread as NAM did not let me re-post the pictures https://www.northamericanmotoring.co...install-6.html

 

I took the switch out, removed the bracket and drilled the hole out a bit larger. I then remounted the bracket, found a longer bolt with matching teflon locking nut and mounted it all up. There is plenty of room at the bottom of the bracket to still mount the alarm switch but it does push the switch up a bit further by a few centimeters since there is now another bracket (the one holding the OCC) stuffed in there. It was a bit tedous but I like the seemlessness of it all.

Overall, as it stands, I'm not that happy with it since it hasn't caught a damn thing. I shouldn't have to buy a separate part or mount it in a different location than the instructions say just to get it to do its original intended purpose.

 

All that location will catch is stuff from gunking up your intercooler WHILE under boost when the PCV system is running that direction.

Mine has also just caught a little there....But that little bit could coat an intercooler pretty well

 

Installed on 4-22-2010. Emptied about 6 ounces from the catch can on 6-5-2010. This is with the boost tap in place. I removed this goop with a syringe via the dipstick hole.

 

Ok, now I'm nervous. I installed mine in April using the boost tap plug on the PCV port to make sure all the airflow was routed through the CC. Checked it last night and it was bone dry. Not one drop came out when I pulled the drain plug and tilted it into the funnel. WTF? Anyone know what might be happening?

 

Hook it up backwards?

 

I don't see how. The CC doesn't have any indicators to suggest ports are air-flow directional.

 

OPC how many miles have you driven since you installed the OCC and boost tap?

 

Since April, I would say 2000miles.

 

I am not finding anything other than a few drops as well. I have driven about 4k miles since install and only a little goop on the screw but nothing comes out.

 

I have the BSH OCC also, as well as the alarm.

I have started to see small deposits on the dipstick after 500 miles. I have no boost port tap either. 20000 miles on my clock.

I managed to mount my OCC on the hood alarm mount just by taking the alarm switch out of the mount, unscrewing the mount and just slid the can bracket in and screwed it back in place. I still run the fresh air intake hose so I had to use just one screw to attach the can to the bracket and mount it high.

here is a quick picture, although it doesn't help much to show the mounting.

And BTW, it is not possible to hook the BSH OCC up backwards. It will operate with the hoses on either way.

 

Unless you need a ring job, the relative humidity of where you live is the biggest factor in phlegm accumulation in the can. When the motor cools down at night that humidity condenses in the motor and then gets blown into the can when you start up in the AM. The baffles then trap it there along with the nasty crud. Unless you've got a long commute the engine bay heat doesn't have time to boil it off. Around these parts, humidity is the least of our worries, LOL.

 

Ah, humidity. That is not something we often worry about here in Central Arizona. Thanks for the analysis, Dwight.

 

Just thought I'd add my 2 pfennigs to the OCC confusion, LoL. I'm using the 42 Draft Design OCC with the BSH boost port. IMHO, their baffling is more efficient than BSH's and is designed so that all the vapors are forced through the baffles. Check their site. After ~12K miles, I emptied mine for the first time. Had at most 2tbsp of incredibly nasty gack in it. The main thing is that the outlet tube of the can was bone dry. Wasn't really expecting that, but I'll definitely take it!

PS: Here's a pic showing install.

 

I have since added the dual boost tap/ blockoff and forgot to empty mine for about a month.. It was almost too late! I have about a half liter of REALLY nasty stuff I dumped out. Some of is was so thick I had to spray the inside of the can with brake cleaner to loosen it up.. I now will attempt to do this every 2 weeks at a minimum!!

I installed my BSH and boost tap in the summer and for the most part, the can was DRY as a bone. Then as the months got colder and winter struck, the can has been loaded up with water and yellow guck. So it does work.

Everyone should have a can like this on their mini. Too many proven cases of bad things happening in the head without it given the design of the fuel delivery.
