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.
A note for the exhaust cam sensor
The Rigid Ultralight covers, when needing to use the exhaust cam sensor, utilize dowels that perfectly align the valve cover to the 2JZ cylinder head using existing machining in the factory 2JZ head. This allows certainty that the exhaust cam sensor will be located in as perfect and repeatable position as possible. A custom camshaft must be used in order to use this valve cover in this fashion.
