It is the end for the year 2010 which we all welcome the year of 2011, and one of the notable news in the year of 2010 in Malaysia is the number of Bus crash accident, which a numbers of victims lost their life.
And after the all the investigation, which may lead to a lot of reason like human error (blaming on driver reckless), road condition (blaming on the road design which should not have a too dangerous curve) and the latest which had come up with the statement that it may cause by the bus parts itself.
Some said the duty of the bus parts should be reduce,
In my very own personal view, though parts did cause a lot of problem on the safety of a bus, but to prevent the use of imitation parts or low quality parts actually should come up a very stringent system.
Currently local bus operator may have their own designated repair workshop, but the maintenance flow for every workshop may vary and the purchasing procedure for the parts are also difference.
What we can do is to copy the system of our neighbour Singapore, on how they carry out their maintenance in their Taxi fleet belonging to ComfortDelGro Corporation Limited, which have over 15,000 Taxi under their Company.
I am personally very impress with their professionalism on carry out the maintenance and the best part is their strict requirement when purchasing the parts.
As one particular supplier wish to supply the parts for them, not only you need to give them a good quotation, but before the parts is use widely into their Taxi, you need to give a few sample for them to test on the lifespan of the parts in their Taxi running environment as their requirement is totally difference from those on passenger car.
As such, some parts may need to custom manufacture by the factory to meet this requirement.
So why not the Government with the related Ministry to setup a centralize Bus maintenance centre and carry out the Bus maintenance in a more systematic wise.

The SsangYong Musso is a SUV manufactured by the South Korean automobile manufacturer SsangYong Motor Company, from 1993 to 2005.
First produced in 1993, the car featured a Mercedes-Benz petrol engine or a diesel engine. The car was designed by Briton Ken Greenley and received the Auto Design Award from the Birmingham Auto Show hosted in 1994 and 1996. Also known for its off-road abilities, the vehicle won the Pharaohs Rally of Egypt for 4WD vehicles in October 1994.
The Musso seats five people and its wheels are fit for off-road driving, similar to its smaller sibling, the Korando. The SsangYong Musso Sports, a Musso variant with a truck bed, was released in later years.
The Musso is available in Russia as TagAZ Road Partner, produced by TagAZ in Taganrog, Russia (since 2008) and also in Iran as Musso, produced by Moratab Khodro Co. (since 2003). It was sold in Vietnam by Mekong Auto Corporation from 1997 to 2005.
The tough SsangYong Musso comes with a 2.9 litre intercooled turbo-diesel 5 cylinder engine. You have the choice of either a manual or automatic gearbox. Combine the powerhouse to your preferred gearbox option, and you have a vehicle that is great on fuel, while providing plenty of pulling power and refinement. Take the 4 wheel drive Musso off-road, and the impressive levels of grip and ground clearance become apparent when the going gets really tough.
As SsangYong had a technology-sharing deal with Mercedes-Benz at the time, the decision was made to sell the Musso as a badge-engineered Mercedes-Benz model in some markets. This was supposedly to allow SsangYong to gain footholds in new markets without having to build their own infrastructure (utilizing existing Mercedes-Benz networks) while giving Mercedes a competitor in the then-booming SUV market.

In the earlier post, we have touch about the Mitsubishi Lancer V6 engine 6A10 which is modified on some of the Proton Wira model locally, have the similar design of engine like Proton Perdana V6 6A12 engine, the only thing is the cylinder head gasket of 6A10 have a smaller gasket bore diameter.
Not only Proton Wira have the modification of engine, even for the Proton Perdana V6 model, some have install a imported version of 6A12, which some said it is MIVEC engine, since it is also from the 6Aseries, the more clear difference is the rocker cover design, under the photo on this post, the upper rocker cover gasket is for the imported 6A12 model in local market while the lower one is the normal use on Perdana V6.

Except for the TDO5 turbo housing gasket which use on Mitsubishi 4G63 range of engine like VR4 and EVO model, other engine model which bore on with turbo also need the similar gasket.
As the gasket on turbo housing need to stand on high temperature and pressure, it just can not use the normal gasket material unless you have the time to change it everytime it blown up.
Photo in this article show the gasket use on the Nissan SR20DET engine which Silvia or Primera turbo, some may call it Skyline but I prefer to call it Skyline when it is using RB25DET or RB26DET engine.

Is engine keeping exhausting white smoke after the head set gasket replacement have anything to do with the failure of the said replace gasket? When a foreman wanted to claim the gasket due to this reason it is really headach, as the real problem may not come from the gasket, it may occur due to Head Bolt didn't replace, or engine valve failure.
Any way we may give a quick glance on the engine smoke problem as below,
A glance at an engine's exhaust pipe can be both frightening and enlightening. There's a moment of panic when a thick cloud of black smoke rolls out of the tailpipe. Sometimes the cloud is gray or white. What does it all mean? Should you shut down the engine and call for help? The good news is that most engine smoke signals don't mean immediate trouble. Some smoke is a normal sign of a healthy engine. And some of it means the power plant is headed for serious surgery. But it's easy to interpret engine smoke. Just consider the chemicals and combustion process inside the engine, and take note of the outside air temperature. Normal engine exhaust is composed primarily of water and carbon dioxide (the bubbly stuff in soft drinks). Gasoline and diesel fuel is a hydrocarbon that creates intense heat when combined with oxygen from the air. The fuel's carbon atoms go into (CO2); the hydrogen atoms go to produce (H2O).
When the engine and exhaust pipe system is fully warmed up, the exhaust is a hot stream of moist carbon dioxide (and traces of other chemicals). The mixture is colorless and invisible, except in cold weather when most engines produce white exhaust for a minute or two after first starting. This is because the exhaust gas cools down when it runs through the pipes and muffler. The cool water droplets can freeze rapidly when they hit the outside air, producing a visible cloud of ice crystals. As the pipes heat up, so does the exhaust gas. It still ends up freezing, but over a wider zone because it takes longer for the water drops to cool down, and they're farther from the tailpipe. But white exhaust can mean problems. Here's a rundown of colors and conditions and what troubles they may indicate.
Steady white smoke; warm engine; any air temperature. This is bad news. The engine's coolant is leaking into the combustion chamber and creating a steady flow of steam. Caused by a leaking head gasket or a crack in a cylinder head, most commonly in the exhaust port area. Usually requires serious surgery on the engine.
Puff of white smoke during cranking, before the engine starts; cold engine; gas or diesel. This smoke is unburned fuel vapor being pumped out the exhaust pipe. The white is tiny droplets of fuel. In a gas engine, the spark plugs aren't firing, or the fuel mixture is too rich to ignite. It may mean the choke plate is stuck closed, or a load of bad gasoline. In a diesel, this cranking smoke indicates defective glow plugs, but may also come from low compression caused by worn rings or valves.
Gray smoke seen only briefly when the engine first fires up; gas or diesel. This is engine oil that has gotten into the cylinder head combustion area or onto the back side of the exhaust valves as a result of worn valve stems or seals. The oil smolders and smokes at first, but then burns off when the engine gets running, and the smoke disappears. This can be an early warning sign of serious trouble. But if the engine isn't using a lot of oil, it's not a fatal condition.
Gray smoke when the engine is warmed up. Usually appears when the engine is accelerated and may be especially notable when the engine is idling. This is unburned oil drawn into the combustion chamber past worn rings or valve guides. In the best case, the oil is just too thin (old oil, wrong weight) and is slipping past the piston rings and valve seals. The oil sump may be overfull. The cure is a simple oil change. But that won't solve gray smoke resulting from a worn engine. In the worst case, gray smoke means the engine needs replacement or serious internal repair.
Black smoke in a steady stream; cold engine, gas or diesel. Black smoke contains carbon particles from fuel molecules that have broken down but have not burned completely. On gas engines, this can mean the choke is not fully opened, the air filter is badly clogged, the ignition system is not firing every time or the carburetor or fuel injection system is set too rich. Normally fixable without tearing down the engine. On diesels, black smoke during warmup can result from a plugged air filter. It can also be a sign of weak compression in one or more cylinders or a maladjusted injection system. In gas and diesel engines, black smoke means excess fuel in the combustion chamber, which washes vital lubricating oil off the cylinder walls. Get it fixed quickly.
Black smoke, in occasional puffs, warm engine. In diesels, black smoke is normal when the engine is suddenly put under load. Modern (mid-'90s and newer) diesels generally limit this puff of particulates, but it may still be visible. The diesel's governor injects extra fuel to kick up the engine speed and power, and this excess fuel makes black smoke while the engine is revving up. It usually disappears in a few seconds. If it continues while under steady load, there may be a leaking fuel injector or incorrect adjustment of the fuel injection governor. Gasoline engines typically don't belch black smoke under sudden load, but they can if the accelerator pump is set wrong, the choke plate is partially closed, or the air filter is filthy. If everything checks out mechanically with the engine, there may be something in the drive line (like dragging brakes) that is causing excess load.

Honda "Insight" hybrid engine has an eco-freindly heart. The Insight hybrid uses two distinct power sources- an electric motor and i-VTEC engine. The hybrid system enables the Insight Hybrid to achieve better fuel efficiency and enhanced performance.
IMA which stand for 'Intergrated Motor Assist', with 1.3L i-VTEC + IMA which will produce maximum power of 65kW [88PS] + 10kW [14ps] and maximum torque of 121Nm [12.3kg-m] + 78Nm [8.0kg-m]
While the 1.3Li-VTEC engine serves as the main power source, the IMA system provides the additional power as and when it is needed. The acceleration performance is comparable to what one might expect from a 1.6L engines.
The Mitsubishi i-MiEV SPORT AIR explores the future possibilities for zero-emission vehicles, placing a greater focus on exhilarating driving pleasure. The concept model exemplifies the balance between environment and dynamic performance implied in the tagline Drive@earth, and highlights the benefits of Mitsubishi electric vehicle drivetrain - powerful, instant torque, superb handling with lower center of gravity, zero on-road CO2 emissions.
Together, these features along with the car's "clear cutaway" top allows the driver to enjoy the exhilaration of fresh-air motoring while also highlighting its eco-friendly qualities.
PX-MiEV, powered by Mitsubishi Motors' new plug-in hybrid system, this eco-friendly crossover concept pushes the envelope for electric-powered vehicles with extended range. The front and rear wheels are powered by two permanent magnet synchronous motors and a 1.6L DOHC MIVEC petrol engine gives additional generation for longer distances or supplemental power of higher speeds.
With these, a pleasing, safe and comfortable ride is acieved while conserving energy. In addition, to maximize effective use of the drive battery, the vehicle also doubles up as an emergency power source in the event of natural disaster.
The next generation of speed and good looks is realized in the all-new Nissan 370Z Roadster - a dashing two-seat convertible with fully automatic power-operated soft top.
With a shorter wheelbase, reduced weight, 7-speed A/T with paddle shifters and an advanced VQ37VHR 3.7L engine, it gives exceptional levels of acceleration and handling, while providing a comfortable interior with minimun wind buffeting - even with the top open.
Its dynamic design is built for style and speed, with aerodynamic shape that accentuates the 370Z's curvaceous features. More importantly, it delivers the performance of a sport car - and looks good, with the top open or closed.
The Nissan Juke ushers an all-new genre of automobiles known as the compact sports crossover. The Juke's unique design is proof of nissan's constant need to challenge conventions, and take everything we know about automobile design to the next level.
The Juke is a dynamic blend of compact sports car agility with SUV toughness. With a brand new 1.6L Direct Injection Gasoline Turbo (DIG-T) engine, a new-generation XTRONIC CVT transmission system and rigid suspension, the JUKE provides smooth acceleration, superior handling, improved driving stability and unsurpassed comfort. So you can enjoy an easy driving experience with a very unique car.

When I'm importing the "KP" brand full set gasket and head set gasket for Mitsubishi 4G63 VR4 model, it is interesting for me to find out the content include the gasket as above picture which it is not included in other brand.
After that with some info from friend, they tell me it is for the gasket on the turbo housing which they call it TDO5.
And what is TDO5, just upload an image as above for a clearer picture, it should be not too strange for those playing on EVO turbo engine.
Where is the gasket place to? It should be place in this area.
