I'm not sure the oil pressure would drop with a bent valve. I wouldn't drive it at all but if your driving to shop or home and don't want to pay to have it towed, drive real slow.
The VG30E motor is an interference motor, with 0 valve clearance.
pressure relief valve relief the excess pressure which is developed in the syatem, while pressure reducing valve reduces the pressure and supply it to the system.
Depends the engine, it is usually on the side of the engine. On the VG30E it is on the drives side, and if you had the new part, or knew what it looked like, you would see it.
IF YOUR ENGINE IS A VG30E..ITS ON THE BACK OF THE TOP PART OF THE INTAKE MANIFOLD TOWARDS THE DRIVERS SIDE IT THREADS IN AND HAS A HOSE RETURNING TO THE REAR VALVE COVER............ALL THE BEST .............BUDDY MACK..
no pressure release valve
The 1987 Nissan Maxima VG30E engine uses hydraulic valve adjusters (also known as "cam followers") which cannot be adjusted. Therefore, there is no specific valve clearance. If you hear valve noise, it could indicate that there's either excessive wear of valve train parts or clogged hydraulic adjusters.
A pressure valve is usually installed on water systems to prevent excess water pressure from destroying fixtures or other plumbing components. When the pressure exceeds the valve ratings the valve opens and releases water/pressure from the line.
Too much pressure or defective valve.
pressure-relief valve
The set pressure is the pressure at which a relief valve starts to open. When the valve is open and relieving, the pressure will be higher or lower than the set pressure, depending on the system and the valve design. That is the blow-off pressure.
A pressure regulator is a control valve that reduces the input pressure of a fluid to a desired value at its output.
To regulate the pressure to a pre-determined amount.
