Oil catch can that will fit with an AP intake?

Relique · 10-16-2019, 09:28 AM

I have a 440xi GC with an AP intake. It is a pretty big intake and leaves little room. I have a turbo upgrade coming up and wanted to install an oil catch can. Are there any options that will fit with an AP intake? Apparently the BMS oil catch can requires their intake to fit. Here are comparison shots between intakes. First one has the catch can pipes installed around it but that won't fit around the AP intake I don't think.

Best bet is to do something custom. You can get A/N adapters for the PCV fittings and then buy a universal kit and mount it behind the intake over the turbo, or on the opposite side of the engine bay. Possibly even under the cowl if you find space.

You'd need something along the lines of this that will clip into the OEM connectors and allow universal AN braided lines to screw in.

It'll be more robust than the silicone hoses that BMS uses too.

That is a good suggestion. Any universal kit you can recommend?

I have this one on another car. Has a few different bracket options. Then you just need braided lines and the adapter.

You're making me want to dig around my engine bay and see where one could be installed. I really feel like there's room under the cowl cover, but not sure how the lines would route in and out of there.

Just mount the BMS OCC in a different location if your intake is where they suggest placing it. Looks it plenty of space next to your air filter.

I'd be concerned about pinching the silicone hoses.

It looks like there is plenty of space to me, your filter probably can slide in a little more too if needed. The nice thing about the BMS kit is the plug and play adapter for the bottom line so you don't wind up having to cut or undo anything you can't easily put back together to stock.
