Driving in second gear at 65+ mph It's definitely not great. The redline is there for a reason. The speed limiter can be either an ignition cutoff or a fuel cutoff - both will make the car feel very shaky. The most common bad consequence of an overspeed condition when the engine speed limiter fails to thwart the operator is a bent valve.

CSI: Engine Bearings: When Good Bearings Go Bad Overloading may be caused by vehicle operator error. Excessive idling can result in an oil film that can’t support the load needed. Engine lugging can distort either (or both) the crankcase or crankshaft, affecting either (or both) the connecting rod and/or main bearings. Hot rodding, or forcing excessive loads, can similarly affect the bearings.

Dieseling Potential causes. Dieseling can occur for several reasons: Built-up carbon in the ignition chamber can glow red after the engine is off, providing a mechanism for igniting unburnt fuel. Such a thing can happen when the engine runs very rich, depositing unspent fuel and particles on the pistons and valves.

- You generally don't. Expect the pistons and cylinders to be badly damaged, and the pistons may even be permanently galled to the cylinder walls. Expect every bearing to be destroyed, and expect your connecting rods and crankshaft to have been warped by the overheating associated with underlubrication.

- Do NOT run an engine like this. Oil and water don't mix and, in an engine's combustion chambers, water is very abrasive and can cause damage to everything …from sensors to seals to pistons and cylinders. Plus water will also bind up the oil and prevent it from lubricating anything which makes a bad situation worse.

Squish (piston engine) Squish is an effect in internal combustion engines which creates sudden turbulence of the fuel/air mixture as the piston approaches top dead centre (TDC).In an engine designed to use the squish effect, at top dead centre (TDC) the piston crown comes very close, (typically less than 1mm), to the cylinder head.quish is an effect in internal combustion engines which creates sudden turbulence of the fuel/air mixture as the piston approaches top dead centre (TDC).

- Where you really get wear and tear from high revolutions is when the engine isn't warmed up. That's because the engine oil hasn't had a chance to reach its proper viscosity and coat all the moving parts. If you see an engine burning oil, it's probably because it was rev'd too high, too often without being warmed up.

4 Reasons Why Engines Lose Power Over Time And How To Win Your Horses Back 3. Compression. For old engines, maintaining compression can be a bit of challenge. Compression-related issues are often a major contributing factor to a loss of power, and the fixes aren’t as easy as some of the other reasons, simply because metal components have worn over time. There are several different ways an engine can lose compression: Worn Piston Rings.

Oil sludge Oil sludge or black sludge is a solid or gel in motor oil caused by the oil gelling or solidifying, usually at temperatures lower than 100 degrees Celsius.Oil sludge can be a major contributor to internal combustion engine problems, and can require the engine to be replaced, if the damage is severe.ludge is usually caused by a poorly designed or defective crankcase ventilation system, low engine operating temperatures, the presence of water in the oil or crankshaft-induced cavitation, and can accumulate with use.

National Motorists Association Blog And water does not work too well as a fuel in an internal combustion engine. Water contamination can cause hard starting and rough running until the excess H20 is purged from the system. More seriously, it can also contribute to internal rusting of the fuel lines and tank.

- “Wet stacking” is a term that originally described a diesel engine dripping a thick, dark substance from its exhaust pipes or, as they’re often called, “stacks.” The dripping exhaust stacks were called “wet stacks,” and the engine was said to be “wet stacking.” The condition is caused by operating the engine at light load for extended periods, ...

- You can't undo the flush. About all you can do is make sure all the flushing chemicals are now out of the motor to reduce potential damage. To me that means another oil change perhaps in a few days and a few hundred miles. Take that TSB to the oil change place and negotiate for another oil change on them.

- Here I run the Yanmar on the shop fuel. I think the computerized diesels (E350's and the GLK250)bad shifting and hesitation can be explained. If the computer has to inject more fuel to maintain the same power because this fuel is crap, the calculated load on the engine is higher than it should be.

Subaru Forester -- check engine light, flashing cruise control, misfiring cylinder, rough idling Subaru Forester -- check engine light, flashing cruise control, misfiring cylinder, rough idling. I have 2006 Subaru Forester that is idling roughly. 90k – oil change every 3k miles. Per diagnostic codes I learned that the 2nd cylinder was misfiring. I replaced the coil, spark plugs, ignition wires, and an airflow sensor. Yet, my car still idles rough. The check engine light is solid and the cruise control is flashing.

The Seven Most Common Hydraulic Equipment Mistakes A clogging indicator is the crudest form of this device. A better solution is continuous monitoring of pressure drop across the filter. Mistake No. 3 – Running too hot. Few equipment owners or operators continue to operate an engine that is overheating. Unfortunately, the same cannot be said when the hydraulic system gets too hot. But like an engine, the fastest way to destroy hydraulic components, seals, hoses and the oil itself is high-temperature operation.

What Can Cause a Car to Hesitate? Engine hesitation can be a result of low fuel pressure, vacuum leaks, worn or dirty spark plugs or bad spark plug wires. A weak ignition system can lead to misfiring, which can also cause hesitation. Continue Reading.

- Avoid overfilling your crankcase. Too much oil can cause the same type of engine damage as not having enough. Air bubbles form in the oil, reducing overall lubrication. The resulting friction and metal-to-metal contact can cause premature part failure.ark oil is not only dirty; it has also lost much of its ability to coat and protect engine components. Manufacturers recommend changing the oil in your small engine after every 25 hours of operation. For a new engine, you'll also need to change the oil after the first five hours of operation.

Leg Extensions Vs. Dumbbell Lunges By definition, dumbbell lunges are done using dumbbells as resistance. However, if the size of dumbbells you want to use for your lunges is being used by someone else, you can always improvise by holding the appropriate size weight plates in each hand instead. Leg extensions can be done using various equipment.

What is the redline of an engine? What is the redline of an engine? All engines have a redline, which is the maximum rpm value they can accommodate. Beyond the redline, the engine will explode. Since you would probably prefer that your engine not explode, you have to keep an eye on the redline, especially in a manual-transmission car. When you shift gears in a manual transmission car, you're making sure that the engine stays below the redline. To shift gears, you move the gear shift and hold down the clutch. The shift lever controls rods that control forks that engage the gears. The clutch is what connects the engine to the transmission.

Is engine flush safe? Is engine flush safe? I just bought a 1985 ford bronco XLT...it seems to be a little sluggish because it's sat for quite a while. I read that engine flush can completly ruin your engine because it breaks down the oil deposits and it gets into places where it can jam up stuff and seize the motor. I need some advice here.

Diagnose Engine Noise ENGINE CLICKING NOISES. A clicking or tapping noise that gets louder when you rev the engine is probably tappet or upper valvetrain noise caused by one of several things: low oil pressure, excessive valve lash, or worn or damaged parts.n engines with hydraulic lifters, oil pressure pumps up the lifters when the engine is running to maintain zero lash in the valvetrain. This results in quiet operation. So if the rocker arms are clattering, it tells you something is amiss (bad lifter or worn or damaged parts) or the rocker arms need adjusting.
