While the Chevy LS Engine is one of the most popular powerplants for hotrods today, they all suffer from this same issue. The oil pump is no longer sitting in the oil during cold starts. When the pump reaches this maximum desired pressure set by the relief spring, the spring compresses, opening the valve, which then bypasses a given amount of oil to maintain the maximum pressure. The tray traps the oil as soon as it leaves the crankshaft, and retains it below, allowing the scavenge pumps to do their job. Proper oil management will ensure that there is enough oil volume in the sump to keep the end of the pickup tube submerged in oil, adds Osterhaus. Start the motor up with the drain plug out, and the oil pressure gauge will read almost where it was. And since LS30 has higher levels of ZDDP than other passenger car motor oils, its the best choice for high output engines that regularly see high rpms. Oil Pressure Problems!!! 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. We'll send you raw engine tech articles, news, features, and videos every week from EngineLabs. He says that improper modifications to the oil pickup can result in aeration and cavitation. The criteria for setting the code is very basic. They are both positive displacement pumps. Why did the NASCAR guys go down to 15 pounds of oil pressure? This will reduce the pumps volumetric efficiency. Over the last 10 years the LS engine has rose to prominence. One notable item brought to light is that the oil pump in past engines like the small-block Chevy was driven from the camshaft, which turns at half engine speed, and the LS-style pumps are driven at full engine speed from the crankshaft. And then that valve will find a place that it likes and float there. Engine Oil System Technology. We implemented dry sumps on those vehicles because of the lateral G capabilities and anticipated track usage., The new LT1 engine in the 2014 Corvette Stingray also uses a dry-sump oiling system.

Verne Schumann of Schumanns Sales & Service says that youve got a couple of inherent problems with the LS engine. The higher the volatility rate, the more oil disappears from the engine. Some racing classes will not allow a dry-sump system. The deep skirt block can create more issues than it solves, however. They started introducing better-flowing cylinder heads, larger-displacement engines, and freer-flowing intake and exhaust systems that allowed the engine RPM limits to go from what was originally 5,800 to whats about the moon these days. It permits the air conditioner and other accessory-driven items to remain in place. Thanks for getting back to us on what you found. Other advantages of a dry sump system include a remotely mounted oil tank for increased capacity, the ability to easily add remote oil coolers, more consistent oil pressure, adjustable oil pressure, improved scavenging and increased ring seal due to greater oil pan vacuum.. OE engineers calculate the total volume of oil necessary to lubricate a given engine at maximum load and then size the pump accordingly. Often it is much easier to add a slightly higher volume pump than to refurbish the lifter bores with aftermarket bushings. Its typically the O-ring on the pickup or if you had a issue with the cam retainer plate. oil pressure light to flicker when staging the car or at low engine speed situations. There is a large, 8mm Allen plug in the front of the engine on the driver side that, when removed, has direct access to the oil pump. All small- and big-block Chevys employed a simple spur gear pump driven off the camshaft.

He explains that the engines highest specific rate of demand (gallons per engine revolution) is at hot idle. Also, theres our fluidic dry sump pan that has cavities to make oil even more accessible to the scavenge pumps. With oil pumps, more pressure is not necessarily better. Traditional methods are not as effective to overcome some of the common LS oiling issues. This issue can cause oil consumption issues. These will occur in any pump as the speed increases to the point where the oil can no longer fill the internal pumping chambers. This creates deposits that impede exhaust flow and reduce power output. There is quite a bit of confusion surrounding this simple little seal since there are two different seals that can be used. My car is about as extreme as they come. The OHC engine has featured up to 5 valves per cylinder to increase it's performance capabilities.
