Here are some more information for Cylinder Covers:
Nowadays it is either Hybrids or Diesels and Volkswagen, our friendly neighborhood car manufacturer, has taken economy and the meaning of green a small step further by launching the latest Polo Bluemotion TDI. The small step taken is the fact that it has chopped off one cylinder from the four cylinder diesel and it is only 1.2-litres in size. This was recently paraded at the 31st International Vienna Motor Symposium.
1.2-litres, diesel, a turbo and three cylinders makes 74bhp and about 180Nm at 2,000rpm. This should be more than adequate to move the Polo Bluemotion TDI in city traffic. As an example, the petrol 1.5-litre Subaru Impreza has only about 142Nm torque made higher up the rev range of 3,200rpm.
Three cylinders also mean less engine weight and frictional power losses, and VW says that it has produced the best in terms of the most performance, maximum "acoustic comfort" and weight reduction from this configuration without compromising the engine's thermodynamic efficiency (some say that each cylinder should be around 333cc to around 600cc for efficient combustion to happen).
Well, the only three cylinder I've driven are the ones fitted on the smallest of the Peroduas sold around here. The Daihatsu three pot engines used are not the last word of refinement and are thrummy in nature, it has an off-beat warble that is kind of "full of character" so to speak. However these engines are petrol, and not diesel. So this Volkswagen may be slightly rough, but since it has the latest common rail injection and the turbo is a variable geometry unit, it could be as smooth as those petrol Daihatsu engines. So an assumption is made that there will not be too much refinement lost anyway.
Now back to the story at hand. According to Volkswagen, this car is expected to achieve 3.3-litres per 100 km while emitting only 87 g/km of CO2. The previous gen Polo Bluemotion's claimed figures was 3.8-litres per 100 km. So smaller is better for diesel sipping.
Bluemotion measures include stop/start functions (for those longer than usual traffic light waiting), higher gearing (It is hooked up to a five-speed manual transmission which boasts extra-long ratios - fifth gives 35mph for every 1,000rpm), regenerative braking, tweaked aerodynamics and 14inch low rolling resistance tires on special alloy wheels. The air-conditioning has been removed in this model as well, similarly to the electric adjustment for the door mirror and the remote central locking. So much for getting yourself some cool air during the sunny weather then.
It is already on sale in Europe where oil burners like this is king nowadays. Now who in their right frame of mind would go buy a Toyota Prius which uses a hefty 4.7litres per 100km of petrol? A hybrid makes no sense after this. Buy a diesel. This diesel car saves more of the black stuff than that purportedly green hybrid. In other words, more money saved as well. And if you were to ask me, I'd say way to go, Volks!

Valve Cover Gasket: a Way to Prevent Oil Seepage
Oil leakage from the upper engine is a common problem in automobiles. Sometimes, the oil pumped through the valve oozes gradually through the cylinder. Oil leakage may greatly harm the different engine components. To avoid this problem, vehicle owners should equip their automobiles with a high quality valve cover gasket. This auto part is very important in protecting the entire engine and the cylinder head from oil and water leaks and other fragments.
To fully understand the function of a valve cover gasket, vehicle owners should first know the function of a valve cover. The valve cover protects the valve trains. To lubricate the valve train, oil is pushed through the pushrod and diffused directly beneath the valve cover. The valve cover is the one that lubricates the rocker arms of the engine. To avoid leakage while the oil is in circulation, it is very important that the valve cover is oil-tight. However, some valve covers are prone to wear and tear. Since valve covers are made of very slim pieces of metal, they fail to withstand the pressure caused by tensing up the screws.
Strengthening the function of the valve cover is the task assumed by the valve cover gasket. The valve cover gasket is a protective rubber material designed to make sure that the valve cover properly seals the cylinder. This greatly prevents oil from seeping through the cylinder through which it passes.
Just like any other auto components, the valve cover gasket may be worn out in the long run. This is due to either a breakage caused by engine pressure or natural old-age breakdown. A smell of burning oil inside the passenger cabin of the automobile can be a sign that something is wrong with the valve cover gasket. When this happens, the vehicle owner should check on the valve cover gasket and other engine components right away. If the valve cover gasket is indeed damaged, it is best to have it immediately replaced.

On a DOHC, is the "camshaft housing cover" and the "cylinder head" the same thing?
I think my cylinder head i leaking. But then when I look in the book it says its the camshaft housing cover. Is it the same thing?
No, the cover is just that - a cover. The cylinder head is the top half of the combustion chamber and contains the valves and spark plug and on a DOHC (double overhead cam) engine also has the intake and exhuast cams. As far as replacement, Rakel is right.
Largest atlas of nuclear galactic rings unveiled
An international team of astrophysicists has just unveiled the most complete atlas of nuclear rings, enormous star-forming ring-shaped regions that circle certain galactic nuclei. The catalogue, published in the Monthly Notices of the Royal Astronomical Society, includes 113 such rings in 107 galaxies.
