Important parts are starved of oil and wear down quickly.

Oil passages that keep bearings and moving parts lubricated become blocked. This sludge is a gooey, sticky black tarlike substance that plugs everything up. If the 5.3-liter engine doesnвЂ™t receive oil changes on time, sludge can quickly build up on internal components. We all know how important engine maintenance is to long-term vehicle health. ThatвЂ™s not the end of the 5.3 Chevy engine problems, unfortunately. Either the engine is removed, stripped down to a bare engine block and undergo an engine rebuild with new piston rings, seals, and gaskets, or the complete engine assembly is replaced with a new one. Both cost thousands of dollars in parts and labor. To fix it, there are two common corrections. On some trucks, the problem shows signs as early as 15,000 miles, and it only gets worse. Exhaust is tinged blue from all the oil blowing out the tailpipe. Spark plugs continuously foul because engine oil gets past the piston rings into the combustion chamber. Why does the Chevy Silverado burn oil? It isnвЂ™t an external leak but rather an internal one. WeвЂ™re talking about 3 or 4 quarts between oil changes, and sometimes more. For 1999 to 2017 models, especially the V6 and 5.3-liter V8 engines, oil consumption was a real concern. ChevyвЂ™s Excessive Oil ConsumptionД¬hevrolet Silverado engine problems arenвЂ™t restricted to faulty sensors. ItвЂ™s three to four hours of labor to change, and itвЂ™s just a nuisance to undergo this kind of engine diagnosis for an engine problem that might not be there. The sensor just canвЂ™t get an accurate reading, and it throws the light on for low pressure. ThereвЂ™s a small screen that plugs up with sludge and debris.

The false low oil pressure reading on a 2007 Chevy Silverado and newer trucks is an oil pressure sensor located under the plenum. The 2007 and newer models, though, is a different story. ItвЂ™s a minor problem thatвЂ™s a serious pain to fix because the switch is located behind the intake manifold. Older trucks, previous to the 2007 redesign, have an oil pressure switch that tends to fail. But one of the flaws that plagues Chevy trucks is a faulty oil pressure switch or sensor. WeвЂ™ll talk about true low oil pressure soon. The low oil pressure warning comes on due to one of two things: true low oil pressure, or an oil pressure sensor issue. Have you really driven your Chevy Silverado if you havenвЂ™t seen the вЂњLOW OIL PRESSUREвЂќ warning come on? ItвЂ™s one of the signals that many a Chevrolet and GMC truck owner has experienced firsthand. ThatвЂ™s when the biggest offender comes into play вЂ“ the 5.3 Chevy engine problems. For the sake of this article, weвЂ™re going to focus on the 1999 and newer models.
