Here's a brief article explaining the stock Mazdaspeed/Eco Boost PCV setup, it's limitations, and how PERM's Dual Port PCV Plate may be used to improve upon it. All cars generate pressure in their crankcase, it's the nature of the beast with piston engines, and the Mazdaspeeds are no different. A majority of this pressure results from combustion gasses pushing past the piston rings and entering the crankcase, hence the coined term "blow by". As the rings wear, and this seal degrades... the amount of blow by will increase. Blow by will also increase as the power output of motor increases... Increased power comes from increased cylinder pressure... which will naturally increase blow by. In stock form, there are two ports on the engine that are used to mitigate this issue: one on the valve cover, and one on the short block (just under the intake manifold). And, since the Mazdaspeed/Eco...
Difficulty Level (1-10): 3 Time Required: ~2 hrs Tools Needed: 8mm socket with various extensions & 8mm box end wrench (ratcheting is best) Pliers and needle nose Flat head screw driver Additional Parts Needed for Install: Several feet of 5/8" hose (suitable for PCV gasses and oil) Hose clamps If the PCV Plate was purchased without a Check-Valve Kit ( coming soon ), you'll need a good quality check valve with 5/8" barbs Depending on where the new PCV port will be routed, you may need a 5/8" barb 'T', or various other fittings Before diving in on this install, give this tech article a quick read to make sure you have a solid understanding of the principles behind this product. PCV Theory Installations for this product will vary depending on the current state of your car's PCV setup. Some cars may already be running a sealed catch can between...
