Lightweight

Powerhouse Racing Billet Valve Covers are precision machined from solid 6061 billet and retain OEM fitment. Weight comes in at only 5 lbs. 14 oz. compared to the stock valve covers at 7 lbs 9 oz.

Maximum Breathing

Designed for race cars, the rear ports are LARGE for maximum breathing. Multiple breather options are available for standard breather tanks to dry sump engines running pop-off valves, vacuum regulators and crankcase pressure sensors. For those needing an oil cap, one of the rear ports can be used for an oil cap while the second port is large enough to allow for lots of air to still vent to a catch can.

Additional -12ORB Ports: We've also incorporated two additional -12 orb ports near the front of these valve covers. We did this to even further enhance the breathing capability of these covers by providing locations for lines to PHR/Dailey Engineering Vacuum Pump Kit. But this also allows for even more breather setup possibilities.

Quick Release Coil Cover

Also available is the PHR quick release coil cover for those running coils that can fit between the valve covers. This coil cover uses simple quick release buttons to allow for removal in just seconds.

Features

• Removable baffles for easy cleaning
• Rear sensor port for measuring crank case pressure
• O-ring cord seal
• Only 5 lbs 14 oz combined weight
• Work on both 2JZ-GTE and 2JZ-GE engines. 2JZ-GE engines must use front facing intake manifold.

Valve Cover Options

These valve covers sport a single -20 ORB opening on each one. You are able to select your options for fittings. -12AN, -16 AN, -20 AN, -20 ORB oil cap, or -20 ORB plug each sold separately.

Sealing with common cord stock

They use o-ring cord stock for sealing, all the way around the cover, including over the front cam cap with very precise tolerances. This allows race teams to carry some cord stock in their trailers to replace is the valve covers ever need to come off with very minimal expense over the factory valve cover gaskets. 

The cord stock is fully compressed into the valve cover allowing the valve cover to come into full contact with the mating surface to act as a further heat sink as well as making a solid precise mount of the valve cover. A dab of gasket maker or "FIPG" is all that is needed in the corners of the front main cap to get a great seal and that very small amount of sealant makes cleanup simple.
