For these reasons, healthy levels of magnesium have been linked to deep, undisturbed sleep. Consequently, low levels of magnesium can contribute to frequent nighttime wakings. Magnesium deficiency has been linked to several insomnia-inducing conditions, including restless leg syndrome (RLS) and night terrors.
Scuffing is another condition that can damage pistons. Scuffing is often the result of overheating, but loss of lubrication, detonation and preignition can also be contributing factors. When an engine runs hot, the pistons swell. This reduces the clearance between the piston and cylinder walls. The cylinder bore can also distort adding to the problem.
Your car's engine compression can tell you a lot about the overall health of the engine. If your car is blowing blue smoke out of the tailpipe, or if your car is losing lots of oil, you could have a bad piston ring. This will also cause low compression in that cylinder, and a compression test will tell you.
