Oil Restrictors
Oil Restrictor for Merlin II Engines has an oil restrictor kit. It should not be used with hydrau. lifters. There are Merlin II blocks. It screws into the existing lifter gallery cleaning plug holes at the back of the block. It has a 1/16 inch orifice dia. with oil lifter galley bosses. It is flush with a bell housing face. There are 2 per pack.
Allstar 0.055 inch I.D Aluminum Hole Engine Oil Restrictor with Hex Head - Pair features engine oil restrictors that fit small block Chevy bowtie block applications. They have .055 inches i.d. hole and are made from high-quality steel featuring an allen head. The oil restrictors replace the production oil galley plugs at the rear of the block. They restrict oil flow to the top end, forcing more oil to bearings to cut power loss from windage. They are sold as one pair and have two extra o-ring seals which are also included. They are backed by a 90-day limited factory warranty.
These plugs solve the common high-performance engine problem of too much oil in the head area. The plug restricts approximately 75 per cent of the oil to the top end of the engine for better lubrication and prevents oil wastage at the lifters (which will cause windage problems). This also keeps the sump better supplied with oil. Installs easily into the back of the block in place of the stock plugs. Not for use with hydraulic lifters.
