A normal filter can be used to go on the PCV inlet on the valve cover, but at most Emissions testing facilities, the filter will be illegal. You
can easily make a turbo catch can however, that will allow the PCV system to work normally, yet not let oil get into the turbo charge piping. The can will need to have the inlet (from the valve cover) mounted lower then the outlet (to the turbo’s intake), to prevent oil from draining into the turbo intake). Just place a paper towel in the can, and it will prevent oil vapor from getting into the line. As long as the can is placed in a place far from the engine heat, it shouldn’t melt. It
obviously help’s if you get a can (tub-a-ware) with a screw on lid, and also one that is made of a hard durable plastic. Also make sure the fitting’s (from Home Depot) are sealed with an epoxy so they don’t leak. Try to use a 90-degree fitting in the intake tube instead of the stock "slash cut tube". The 90-degree fitting will respond better to the pressure and keep more oil in the engine then the can. |
