Husmen 699 GTO Renderings
If you're new here, you may want to subscribe to my RSS feed. Thanks for visiting!
Emre Husmen, a Transportation Design student from Istituto Europeo di Design (IED) of Turin, Italy has released his renderings of the Husmen 699 GTO.
Husmen got his inspiration from past Ferrari models such as the 250 GTO, 250 TR, P4, and also from the current 599 GTB Fiorano and Alfa Romeo’s 8C Competizione.

The Functions Of Timing Belt
August 9, 2007 by Admin · Leave a Comment
When a timing belt breaks, costly internal damage could occur. Timing belt are normally used on smaller engines but hardly used on bigger engines.
The timing belt is not like the alternator belt, fan belt or power steering belt where by they can be easily seen during maintenance. The timing belt is made from the same material as the rest of the belts and will wear out. Timing belt will not last forever.
The function of timing belt is to keep the camshaft to be exactly synchronized with the crankshaft and distributor. The engine will not run if the camshaft and the crankshaft are not in synchronization.

Steering Wheel Vibrates When Speeding
June 6, 2007 by Admin · 2 Comments
When you drive at certain speeds over 40 km/hour, you feel that the steering wheel suddenly begin to vibrate. This is even when your tires are still in good condition and free of bulges and damaged threads. Sometimes you’ll feel slight vibration but other times you could hear thundering sound which only stops when you slow down your car.
When you drive at high speed, you must know that the balance of each wheel and tires are very important. Wheels will begin to vibrate if they are out of balance. The vibration is transmitted to the steering linkage and the suspension that holds the wheels to the car. If wheel-balance vibration is left unrepaired, the life span of the front and rear suspension will reduce. Apart from that, a wheel-balance vibration also causes premature tire wear, tire failure and damage tire tread.
There are 3 basic ways to diagnose and to solve this problem.

Sound at Tailpipe Out of Tune or Uneven
A good condition car normally produce even or smooth tone at the tailpipe as the engine idles. But if you notice that the sounds are no longer even, where the tone changes rapidly then there’s something wrong.
The simple explanation to this is maybe the spark plugs are not in good condition anymore. It could also caused by worn valve or piston ring.
All internal combustion engines are designed to work as a unit. The power contributed by each cylinder must be the same and in balance. The engine might still run even some part of the engine malfunction but it diminished its overall performance.
We are able to detect the problem by the change in sound or loss of power of the engine.

LifeHammer Original Emergency Hammer

When I first look at the description of the hammer, I was intrigue with its purpose. LifeHammer Original Emergency Hammer (Orange)
It’s a high-quality car escape tool, designed to help prevent automotive entrapment after an accident. The double-sided steel hammer heads allow the vehicle occupant to shatter side and rear windows with its double tipped steel heads, while a safely concealed razor-sharp blade cuts easily through safety belts should power locks become disabled or a safety belt jam after an accident. It comes with mounting bracket (made of tough ABS plastic) for convenient installation, a polypropylene grip and handle, and a florescent pin which glows in the dark for easy retrieval.
I’ll try to look if it’s available here in Malaysia, otherwise I would just buy it from Amazon. I hope I would never have to use this tool but you never know you might need it some day. Consider LifeHammer Original Emergency Hammer (Orange)
White Smoke From The Exhaust Tailpipe
March 30, 2007 by Admin · Leave a Comment
Before this I’ve written about what are the causes of blue smoke coming out from the tailpipe. Today we’re gonna see what’s going on if the smoke is white. Eventhough you’ll see white vapour from the tailpipe before on a cold or rainy day, but now you’re seeing it more often. You also notice that you have to top up water or antifreeze/coolant to the coolant-recovery tank or radiator.
To explain this we need to know how the engine is assembled. Between the cylinder head and the engine block, gaskets are placed. The purpose of the gaskets are to provide an air and water tight seal between the cylinder head and the engine block. When the seal begin to leak, the pressure of the combustion occuring in each cylinder can push air and fuel into the cooling system.

Accutire MS-46B Digital Key Chain Tire Gauge
I found this cool stuff from Amazon. I’ve never seen this in my country before. It’s amazing that you could find something cheap that if you use it regularly, could save you tons of money in term of tire maintenance or fuel milage.
This is because under-inflated tires may cause the vehicle to work harder and therefore decrease your gas mileage, but more importantly an under-inflated tire can actually damage your tires and your vehicle.
With the Accutire MS-46B Digital Key Chain Tire Gauge
The MS-46B is small (it is designed to hang from your key chain) so it won’t feel bulky in your pocket or take up a lot of space in your purse. It’s made with durable plastic to prolong its life span, whether you decide to keep it on your key chain, in your glove box, or stashed in the junk drawer. It has an easy-to-read LCD display that makes the process of airing up your tires more accurate than conventional tire gauges.

I hope we could get these kind of gadget easily here.
Light Blue Smoke from the Exhaust Tailpipe
February 12, 2007 by Admin · 3 Comments
If you notice a light blue smoke from the exhaust tailpipe when you first start the car. The smoke might dies out after a few minutes and will be back only after you restart the car. The blue smoke might also appear when you accelerates the car and also whenever the engine is running.
What happened here is the engine oil is getting into the air and fuel mixture. The engine might need major repair and this problem is caused by few factors. I’ll explain later how you could fix this problem. So basically it’s better if you could make it a habit or routine to check the tailpipe once in a while to observe the colour of the smoke.
First of all, if your car have a transmission which is equipped with a vacuum-operated modulator, the fluid from the transmission modulator maybe leak and being drawn up through the transmission modulator vacuum hose into the engine. Thus the transmission will eventually become low on fluid. It only takes a slight leak to create blue smoke.
Second possibility is that the engine oil return holes in the cylinder head are clogged and this will cause the blue smoke to occur only for a few moments when you initially start the engine. The clogged holes will cause the oil to pool and be drawn around the valve stems. What the mechanic will do is he/she will remove the valve rocker arm cover or covers and check the oil returns.
Another possiblity is the worn valve seals could cause blue smoke too. Valve seals are made of little rubber seals and their function is to keep engine oil from being drawn down between the engine valve and the hole in the cylinder head into which the valves is fitted. Oil can be drawn into the engine intake manifold when the valve seals wear out.
The mechanic still need to remove the rocker arm cover to be able to reach the valve seals. In a worse case scenario the valve guide or hole in the cylinder head might be worn out, allowing too much space between the valve stem and the valve guide hole. This will cause oil to leak into the air-fuel mixture and be burned together in the cylinders.
If the problem with the valve seals is not tackled, the presence of oil in the cylinder will cause fouling of one or more spark plugs. You’ll notice that the spark plugs need to be cleaned frequently as they become wet with engine oil.
Lastly, worn piston rings also could allow engine oil to be drawn into the combustion chamber and burnt together with air and fuel. We could assume that generally, but not always, worn piston rings will cause lowered compression. This could be analyzed during engine tuning and it’s best to discover a low compression cylinder before it becomes a major problem.

Why A Car Needs A Radiator
Since there are numerous moving mechanical parts in a car’s engine, the continuous movement of those engine parts creates friction which in turn creates heat.
To reduce the friction, the effected parts will be lubricated when the motor oil is pumped throughout the engine. However, as part of the engine normal operation, the motor oil alone is not enough to dissipate heat as other parts of the engine continue to generate heat and the heat produced often reaches boiling stage. This is where radiator is required.
