What does the Damond Motorsports PCV Plate do, and what does it offer?

The PCV plate is a fully machined replacement of the factory PCV oil separator plate, with a port machined to accept an OEM Mazda PCV valve and o-ring, as well as two additional large -10 ports, thus allowing you to run a variety of PCV and OCC set-ups. With this latest version we have added a baffle plate to help reduce the amount of blow-by out of the PCV plate. 

Incorporating a PCV valve port onto our plate means you are able to maintain the correct amount of vacuum on the crankcase, under all engine vacuum conditions. With the additional ports, you’re now able to easily and cleanly run dual OCC set-ups in whatever configuration that suits your car best to relieve excess crankcase pressure. The PCV valve is held into the the DM PCV plate with a retaining ring, allowing for easier install and removal of the valve.

Damond PCV Plate

I am by no means an expert on these things.

With that said, the functional difference between the OEM plate and Damonds is obvious. The crevices and shaping on the internals of the OEM (which is just plastic) leads to build up and around the PCV output. My vehicle has ~120k and there was a nice layer of build-up on the internals of the OEM plate (to be expected). With Damond's, the simplicity of the design lends to better flow. There is no excess room within the internals (both have baffles, but I believe Damond's is a dimensionally larger) so you get a single PCV flat plate, snug against your block. Plus, the additional ports accommodate different OCC setups - a very good feature for those who do wish to push their engines even further.

A major difference is the angle at which the PCV valve is located. OEM has it sticking up, which, with an OEM setup may be cumbersome to disconnect and reconnect (assuming no new hose is added), but Damond's is coming out perpendicular to the block, giving you a different angle of approach for hose connections for the OCC.

I would suggest this to anyone looking to upgrade the plate to fit an OCC setup, but I do not believe it would be something you should have without an OCC planned. This plate is meant for OCC use, and future growth.

Good product

Great build quality and design. Just a bit tricky to install by needing to take the intake manifold off.
