Improved Racing Adjustable PCV and Turbo Oiling Restrictor Valves
Replace your traditional PCV valve with Improved Racing adjustable PCV restrictor valves for better reliability and increased crankcase vacuum. They are perfect for LS engines with aftermarket valley covers that do not have a built-in PCV restrictor like the factory cover, and they can also restrict oil flow to a turbocharger to avoid flooding the turbo. Improved Racing's restrictor valves can be used on their own, replacing traditional PCV valves in naturally aspirated engines, or combined with a check valve to prevent pressurizing the crankcase under boost in turbocharged applications. Features and benefits: * Adjustable PCV restrictor with 5 pre-drilled sizes: -- 2.6mm, 3.0mm, 3.5mm, 4.0mm, 4.5mm -- Plus, a blank disc with a 1mm pilot hole for custom-drilled sizes * Female -6 O-ring boss ports on each end -- Can be adapted to many different fitting types and sizes (male AN, hose barb, quick connect, etc.) * All-aluminum 6061 T-6 construction with black Type II anodized housing * Each plate is laser-marked with the restrictor hole diameter in millimeters * No moving parts for improved durability over traditional PCV valves

Engine Works Oil Restrictors
Engine Works offers oil restrictors for a variety of engine applications from the 1950s and up. Machined from aluminum, they fit in most small and big block Chevy blocks (except Bowtie) at the rear of the block. Simply replace the oil galley plugs (tapping may be required). These restrictors are not for use with hydraulic lifters. An oil restrictor installs in the oil passages of the engine block. It limits the flow of oil to certain parts of the engine. Engine oil lubricates and cools vital engine components. In most cases, more oil usually means the engine will run cooler and last longer. However, in some specific RACING applications, more oil can actually reduce the performance of the engine. When roller rockers and solid lifters are installed, the amount of oil required by the valvetrain is reduced greatly. Installing an oil restrictor kit will limit the oil flow, reducing the windage created from excess oil draining past the rotating assembly. This keeps the oil flowing where it is needed most—to the rod and main bearings.

Milodon Oil Flow Restrictor Plugs
Don't let oil go to your head! Milodon oil flow restrictor plugs solve the common high performance engine problem of too much oil in the head area. They restrict approximately 75 percent of the oil to the top end of the engine for better lubrication and prevent oil wastage at the lifters (which will cause windage problems). This also keeps the sump better supplied with oil. These plugs install easily into the back of the block in place of the stock plugs. They're not for use with hydraulic lifters.
