To the running engine, the lubrication system is much like the heart and blood of the entire operation. The pump, valves, bearings and oil play a large role in bringing modern engines to the couple hundred thousand miles plus they see these days. The high pressure safety valve, or oil pressure relief valve, is just one of the devices implemented to keep things running smoothly.

While the engine is running, oil is picked up from the reservoir or oil pan for most vehicles. The oil is drawn into the pump, compressed and distributed throughout the engine. At lower speeds the pump generates enough volume to support the rotating assembly. As the engine speed increases, so does pump output. At a certain point the pump is moving more oil than the engine is demanding and the pressure inside the system can reach a level where it can blow seals. The pressure relief valve opens to send oil back to the reservoir and keep the volume and pressure steady.

Oil cools the engine as well so a consistent flow allows the oil to do it’s job, drain and cool off in the pan before returning to the engine. Heavy-duty vehicles generally require an added oil cooler because of the added load.

Problems arise when the demand for oil is greater than the available supply. In this case, the pressure relief valve may be stuck open and allowing too much oil to bypass the system and dump back into the reservoir. If the oil pressure relief valve sticks closed, pressures inside the system can spike high enough to burst oil filter housings or damage oil cooler cores and seals. A stuck-closed valve and low oil level together can run the reservoir dry as well and cause damage to all of the components of the lubrication system including the pump itself.

Modern vehicles include the pressure relief valve in the oil pump housing which can be found inside the engine behind the timing cover or the oil pan. Because of this, a vehicle service manual is mandatory to find the location of the valve as the design varies.

Step 1: Do some homework. Familiarize yourself with the instructions in the manual and the locations of the parts on the vehicle before tearing anything apart. Doing this beforehand may enlighten you about any possible special tools required for the job.

Step 2: Prepare your safety materials. Always wear eye protection when working on a vehicle and it is necessary to use protective gloves to keep the chemicals off of your skin.

Step 4: Drain the engine oil. Drain the engine oil and replace the drain plug now so it doesn’t get lost. Remove the engine oil filter. Once the work is done, you will add new oil and a new filter.

Step 5: Gain access to the pressure relief valve. Locate and remove the relief valve if your vehicle is equipped with an external unit near the oil filter housing. It may be necessary to remove the oil filter housing or oil pan to access the relief valve on some models.

Note: Never reuse an old oil seal as many are made of rubber and petroleum products will weaken rubber materials over time. The seal may not have been leaking before you removed the part, but it surely will leak if the old gasket is used again.

Step 9: Top off fluids. Fill the engine with oil and if you haven’t done so, put on the new oil filter. There are few things worse than starting a vehicle with no oil filter and wasting a gallon of fresh oil.

Note: If the oil filter mounts vertically with the open side up, fill the oil filter with fresh oil. This method avoids a dry start and get the oil moving quickly.

Step 10: Start the car. With the fluids full and all fasteners tight, you are ready to start the vehicle. Start the vehicle and allow it to run for about 10 seconds. After 10 seconds turn the vehicle off and check the oil level. Top off if necessary.

The engine"s lubrication system is back in working order with the proper safety measures intact. Always use the type of oil recommended by the manufacturer to avoid fluctuations in oil pressure that may cause major damage to the engine assembly. The oil pressure relief valve is designed to the grade of oil to be used in the engines service life and you must adhere to the proper recommendations for the best results and longevity of the engine.

All internal combustion engines rely on some form of engine lubrication to keep the metal components of the engine from overheating and becoming damaged due to metal on metal contact. The engine oil pump is responsible for pressurizing and pumping engine oil to the various places throughout the engine where lubrication is required. It is the job of the high pressure safety valve to regulate the oil pressure and make sure that it is always at a safe level, never too high or too low, and always at the correct pressure.

The high pressure safety valve is usually located near the oil pump, and is not usually considered routine maintenance to service, however it can sometimes fail and cause mechanical issues with the engine. Usually a bad or failing high pressure safety valve will produce a few symptoms that can alert the driver of a potential issue.

One of the most common symptoms of an issue with the high pressure safety valve is an illuminated oil light. If the high pressure safety valve fails or has an issue, the engine oil pressure may be disrupted. A change in the oil pressure, especially if unsafe, will be detected by the oil pressure switch, which will set off the Oil Pressure Light.

Another symptom of an issue with the vehicle’s high pressure safety valve is increased engine noise. If the high pressure safety valve fails and oil pressure is compromised it may be possible for the engine to be starved of oil in certain places. Aside from the potential of serious engine damage due to oil starvation, this will cause the engine to produce loud mechanical noises, such as whirring, grinding, or scraping. If you suddenly notice your engine making loud mechanical sounds that change according to engine speed stop the engine and have the vehicle looked at to prevent the potential of serious engine damage.

Another symptom of a faulty high pressure safety valve, one for vehicles equipped with oil pressure gauges, is sudden changes in oil pressure. The high pressure safety valve is meant to regulate the oil pressure, making sure that it stays at a safe level throughout the engine, at both high and low engine speeds. If the safety valve fails, the oil pressure and flow may be disrupted, which may lead to sudden changes in oil pressure. The oil pressure gauge may suddenly change from being in the center, to high or low, or may fluctuate erratically.

High pressure safety valve failure is not generally considered a common issue, however problems can occur under certain circumstances. If you suspect that your engine’s high pressure safety valve may be having an issue, have the vehicle inspected by a professional technician, such as one from YourMechanic, to determine if the valve should be replaced.

Surface-controlled subsurface safety valves (SCSSVs) are critical components of well completions, preventing uncontrolled flow in the case of catastrophic damage to wellhead equipment. Fail-safe closure must be certain to ensure proper security of the well. However, this is not the only function in which it must be reliable—the valve must remain open to produce the well. Schlumberger surface controlled subsurface safety valves exceed all ISO 10432 and API Spec 14A requirements for pressure integrity, leakage acceptance criteria, and slam closure.

Through decades of innovation and experience, Schlumberger safety valve flapper systems are proven robust and reliable. The multizone dynamic seal technology for hydraulic actuation of subsurface safety valves is a further improvement in reliability performance when compared with traditional seal systems in the industry.

The multizone seal technology is currently available in the GeoGuard high-performance deepwater safety valves, which is validated to API Spec 14A V1 and V1-H.

Siemens VOG15 is an electro-hydraulic actuator three-way oil valve design. It provides safety shut-off control for industrial and commercial burner applications. The normally closed port on the valve is rated for safety shut-off function. The normally open port location is on the bottom of the valve is typically used for recirculation of heavier oils.  A 3/4-inch NPT pipe plug (comes with VOG) is in the bottom port for two-way applications. The compact VOG15 actuator opens slowly when power is on and if power interrupts, it closes in less than a second. A visible position indicator on the front of the actuator displays position, and a light indicates when the actuator is on.

The electro-hydraulic actuator consists of a cylinder filled with oil, a piston containing an electric oscillating pump, and a relief system. Supply power to the actuator, then the relief system closes, and the pump moves the piston downward in the cylinder, opening the oil valve. If power interrupts to the actuator, the relief system opens and the oil valve closes in less than one second. A position indicator, visible through the transparent portion of the terminal cover, shows the entire stroke range of the actuator. The oil valve only uses about 1/4-inch of the actuator’s stroke. A light, which is visible through the lower left transparent portion of the terminal cover, indicates when the actuator receives power.

A non-adjustable SPDT POC over travel switch signals the valve closed position after the oil valve has closed. If optional equipment supplies an SPDT auxiliary switch, it changes state when the oil valve is more than 80% open.
