may be falsely blamed. Establish a monitoring program to verify the optimized supply or level is consistently achieved. Then, other suspect causes (the bearing, lubricant, operator, etc.) If so, then a dry-sump system will be preferred over a wet sump. What would be great to see is a option to simulate certain damage like "damaged piston rings" to see what sort of impact prolonged driving with that will have, without having to wreak your car to get there which normally means a radiator has blown … Simply put, if you have either oil contamination or even oil starvation, then this can lead to turbo failure. The late-model crankshaft-driven oil pumps are much larger to accommodate assembly over the nose of the crankshaft. “It may be better streamlined for gas mileage attributes, but as far as the functionality of the oil pump, he says it ends up being detrimental to the cause.”. The older camshaft-driven pumps typically utilized a ½” driveshaft. Oil Contamination. “When we compare the operating speeds, the older camshaft driven oil pumps run at half engine speed and sit in the oil sump,” Osterhaus explains. They’re worried about the 30 GPM of oil that is going through the engine.”, Components: Tips For Selecting Performance Connecting Rods, Products: Champion Modern Muscle 0W-40 for Gen III Hemi, Engine News: Metalworking Fluids and Machining Webinar, Diesel of the Week: Twin Turbo 5.9L Cummins Engine, Engine News: Sonoma Appoints Nick Bublitz as Drag Strip Manager, Service Issues on Ford 4.6L SOHC & DOHC Engines, Carburetor Tuning: A/F Mixture, Air/Fuel Equation, Cleaning Engine Blocks & Engine Cylinder Heads, Ticking, Knocking Noise Complaints: Ford 4.6L / 5.4L 3V Engines. 95% of turbo failures are because of problems with oil starvation, oil contamination or foreign object damage. Catching on Fire. Some racing classes will not allow a dry-sump system. If oil is not present at start-up and while the turbo is running, the bearings will fail. “I’ll go back to the NASCAR example: They’re not worried about 15-20 pounds of oil pressure. Why did the NASCAR guys go down to 15 pounds of oil pressure? • Accidental contamination of new oil during servicing. Lubricating oil needs reinforcement, which is lost when flow becomes restricted or static. As turbochargers can operate at over 240,000 rpm and endure temperatures of 950°C, turbo bearings are under great stress. > In severe cases, irreversible damage to the engine is caused when metallic debris is forced into the combustion chamber, and impacts the piston, valves and cylinder head. “Their pickup tubes are typically much shorter as compared to late-model crankshaft-driven oil pumps, which are located on the front of the crankshaft and run at engine speed. All information as of version 0.15. Starvation may also be used as a means of torture or execution. When the oil light came on, I was in an unsafe area and had to drive another 2 km's (roughly just over a mile). Mounting Errors of Constant-Level Oilers. Piston seizure or piston broken? Released as of version 0.5.3. Even if I had good oil level in the dipstick, it was not enough, because I need more oil to feed the turbo and the oil cooler. Oil Starvation. What causes contaminated oil? “The original LS7 oil pan design allowed the end of the pickup tube to be exposed during high-speed cornering, causing oil starvation. “A couple of late-model applications that come to mind are the GM LS7 and the Ford modular V8s,” says Osterhaus. Any line that carries oil under 60 PSI will also sling oil all over. eSource Archive Subscribe to eSource Follow Us Whether operating equipment is grease lubricated or is oil lubricated, lubrication starvation can hasten equipment damage and unplanned downtime. Oil starvation from mowing at too steep an angle? What is lack of lubrication and oil starvation? Identify the required lube supply or level to optimize reliability.
