Which part is the most important component of your car?

Tires and brakes are the most important and literally the most neglected component of any automobile.

Why this two most vital components are the most neglected on the majority of the cars around us?

Tires and brakes get the least amount of respect despite they are the most important, the most used and abused components on any car. Tires are all black and round and they all look the same. Sorry nothing could be further from the truth.

Tire carcass the structure the material consisting the way it is woven and the belt and materials chosen with the secret recipe of the compound makes it some really complicated piece of engineering.

Look no further than F1 or Le Mans or pretty much any high end motorsport where tire choice will determine of the outcome of any race.  Furthermore without perfectly performing brakes the whole effort is wasted by the entire team.

Braking control and vehicle performance relies on proper traction. Your tires are your only contact between your car and the road so tire choice is the out most importance.

Tire choice should be not decided by on price only it should be guided by a knowledgeable technician an expert in the field wit decades of experience to guide you thru a very important decision with choices based on know how rather than price and or appearance or perhaps by brand recognition only.

Yokohama winter tireProbably you realized too, winter is just around the corner.  The temperature drops and we might get some snow at anytime. This time of the year driving on bald tires has it’s consequences, in most cases sudden, expensive or tragic at worst.

Bald or slick tires belong on a race track only,  please keep in mind race tires are compound specific to maximize traction at all times, which brings us to the point as the current weather in November quite unpredictable we need to optimize traction by installing winter tires.

Winter tires as said above are specific compound to stay soft and pliable in cold temperatures.  The benchmark is 7 Celsius,  at 7 Celsius summer or three season tires will turn into hard rubber like a hockey puck.

Literally any modern winter tire is superior to any 3 season tire commonly called “all season” tires in the late fall and in the winter season. To optimize tire wear and traction, tire pressures should be checked at least once a month and alignment should be checked at least once a year.

BMW Classic Cars in the BMW Zentrum Museum, US

The classic BMW Bubble

One of the car is in the museum, the BMW bubble car from 1950’s. It was called the Isetta and that picture is at above in the front of the Isetta coffee in Spartanburg SC. According to the New York Times, that BMW Isetta looks like a refrigerator on wheels, and someone put on a BMW badge. Its a not an average car, that is for sure!

However after World War II, this car was one of Germany’s premiere luxury brands. It may not seem like much today, but it is the car that the saved BMW, and made them possible to produce some of the most engaging motor vehicles of the last 60 years.

In 1955, the BMW bubble car became the world’s first mass production automobile to achieve a fuel consumption of 3 L/100 km. It was the top selling single cylinder car in the world, with 161,728 units sold.

Classic BMW 319 sedan

The other popular and classic BMW was the BMW 319, see at above. It built from 1935 to 1937 in Eisenach, and had a 1.9L, six cylinder in line engine. The 1911 cc produced 45 HP (33kw) at 3750 rpm and had a top speed of 115 km/h.

Body types were available either in Convertible or Touring Limousine style the Convertible has been a modified version of the Limousine automobile.

Winter tire time is coming soon

Welcome to fall again.

As always and somewhat predictably, as this year again we have the fall in full swing, meaning the temperatures drop. With it naturally road temperatures and tire  temperatures drop, together reducing the  traction available for braking or turning.

When is the time right to install winter tires?

Yokohama winter tire

The magic number is 7 degrees of Celsius. The so called “all season” and all performance tires will become brittle as their compound will partially become nearly hard as solid plastic.

Tire friction requires warm road surface or pliable tire surface to generate any meaningful friction to slow down a moving vehicle at all times.  Since the road temperature is given and cannot be influenced by the driver than we got no choice but choose the softest tire for the job, which are the winter tires.

Winter tires  formulated to stay soft and pliable in extreme cold temperatures.

What we have learned is, winter tires are not only meant for snow or ice but for cold weather driving,  which what they are really engineered for ultimately.

Maximum traction requires the best weather specific rubber to be put to the road for ultimate safety and optimal vehicle performance .

BMW N20 timing chain and oil pump chain issues

Why does early timing  chain stretching happen?

There are multiple factors contributing to this problem, not withstanding the 8 speed automatic transmission is one of the factors in my opinion. North American drivers prefer their cars to be automatic, in this case, the automatic is more economical, than the standard version which is preferred by the Europeans.

You may ask; Why is there a problem with the 8 speed automatic? The problem occurs with our driving habits and the programming of the automatic transmission. In normal ECO mode (the default mode) it will shift up quickly and efficiently to the highest possible gear to keep the fuel consumption at minimum, hence called the ECO mode.

N20 4 cylinder BMW engine 4 Cylinder BMW  N20 Engine

The quick up-shifting in daily driving will keep the engine’s rpm very low, which will cause the 4 cylinder engine to oscillate a lot more than would have been, if it driven on the autobahn at high rpm, where there are no oscillations are really present.

Naturally the chains, the guides are fairly weak design to make them light as possible. Our stop and go driving at low engine loads paired with an efficient automatic exacerbates the problem. Furthermore the extended oil changes also does not help to keep the whole thing properly lubricated for long life.

Needless to say the newer engines and their timing chains has been extensively redesigned to counter this common and often fatal problem.

In any case, if the chain makes noise it must be addressed immediately. All the components has to be replaced. For replacement, only an improved version available from the manufacturer. The replacement components must include the oil pump drive assembly as well, according to BMW repair instructions, also a revised, improved component.

There are multiple special tools required and attention to detail is essential to complete this rather delicate repair procedure properly and permanently.

BMW N63 coolant leak

Most BMW 550, 650, 750 i engines did or will develop a common coolant leak which perhaps resembles a funny slightly stinky smell in the cabin, in turn could escalate to an electrical burning smell over time.

The burning electrical smell could be your alternator being damaged by coolant leaking into it.

Always check inspect the turbocharger cooling lines passing right above the alternator or you will be replacing the lines – hoses and plus the alternator as well, at the same time.

This is not an easy job, due to the dual turbo arrangement in the middle of the engine block V configuration.

Performing a pressure test after repairs is essential due to system complexity.  Both after run electrical pumps should be also tested to prevent turbo charger premature early failure.

There are additional lines under the alternator which should be also inspected with a fiber optic camera to ensure system reliability and performance in the long term.

A picture is worth a thousand words they say, judge it by yourself.

My car’s engine burns a lot of oil. Why?

A car engine that burns oil not only wastes oil, but can damage spark plugs, which will end up in ignition system problem (engine misfire). Sooner or later it  will affect the catalytic converter.  Oil burning can and will also cause higher emissions, resulting in failed emissions tests due to excess hydrocarbon production.

All cars consume oil, at different rates depending on the engine model, driving patterns, engine load, maintenance history, age of the engine, driven km, motor oil quality, etc.

But excessive engine oil consumption should be taken seriously. If you know your car engine burns too much oil,  get the problem diagnosed, before it cause some serious and costly damage.

On occasion could be a simple fix to the problem perhaps a damaged, aged gasket. However there are a few things you should know as follows.

The modern engines of late went thru some serious diet to increase horsepower and to reduce fuel consumption.

The law of physics has not changed, skinny piston rings and valve stems has one thing in common they reduce friction and fail to seal properly in the internal combustion engines of late.

Take a look at to the next photos, to see the differences. Click on the thumbnail to view bigger images.

Today most of the engines are turbo charged for efficiency reasons, in particular to reduce pumping losses. Turbo charging will increase the thermal heat load on the internal components. Once you got thin parts with double the heat exerted on them, equates to baked valve seals, clogged oil scraping rings with clogged piston oil drain holes.

The efficiency war on the internal combustion engines has produced some remarkable output at the expense of engine life and longevity.

For comparison see when I started working as a mechanic a 1.5 liter engine produced 74 horsepower on average. Today they can make as much as 230 horsepower in a moderate automobile.

As I said earlier the law of physics has not changed, the internal parts has been reduced to the bare minimum, so efficiency is the new magic word, unfortunately comes at the expense of reliability.

German Oil Filters. Superior Oil Filtration For Increased Engine Protection

Neglected Porsche Boxster

We often talk about poor quality maintenance where most emphasis put on either on price or lack of time, or both at the same time .

Porsche TireWorn Porsche  Tire. Click on the thumbnail for bigger photo.

You can judge it by yourself, this poor Porsche  has been badly neglected has been driven in with bold tires and a completely sucked in distorted poor quality oil filter. Probably the oil was also inferior quality as well.

Note! Brand name tires, include factory installed tire on brand new  Porsche have built in tire wear indicators. They are molded into the bottom of the tread grooves and will appear as approximately 1/2 in. (12 mm) bands when the tire tread depth is down to 1/16 of an in (1.6 mm).

When the indicators appear in two or more adjacent grooves, it is time to replace the tires. We recommend, however, that you do not let the tires wear down to the extent that you can see on the above photo at top left.

Driving a high performance sport car, like a Porsche with worn tires, can result in loss of control of the vehicle and could cause serious personal injuries or death.

Porsche engineers a magnificent car, engineering excellence is built into every Porsche model, with thousands of finely tuned and intricate parts working in harmony, but they need regular maintenance like most other cars. When you invest in a fine tuned high tech sports car wouldn’t make sense to give it the best care possible, ensuring your initial investment will last years to come reliably?

The answer is clear, give it proper care by providing the best fuel, the best lubricant and German filters. Perform essential services on proven time and distance based by established specialist with the proper know how, as they were designed and intended by the respective manufacturers and engineers.

Tires Care

Every tire tells a story, well this one needs no comment I think. This one has been driven all the way until complete delamination.

Never mind it has been deflated severely, and  it has been completely ignored as the picture shows. Complete carcass failure is the result of zero care of this tire.

overused tiresOverused Tires

Tires are one of the most essential purchases you ever going to make for your car. Choose carefully, price and brand name usually provides an expected quality in most cases, in some instances this theory may not hold that well.

Tire care is essential if you don’t want to get stranded or towed.

Conventional radial tires are resilient to a point, except if they are under inflated. That will destroy the flexible frame of the tire, which depending on the material, perhaps made from nylon or steel or high performance applications Kevlar or any combination of the above.

Run flat tires are less prone to sudden tire failure due to stiffer sidewall construction, this is why more and more manufacturers choosing them on modern late model high end automobiles.

Never rely on visual inflation check on run flat tires, since they will not reveal if they are under inflated as usually clearly visible on conventional radial tires.

Tires should be regularly inspected and inflated cared for especially before and during the summer as heat generated by the tires friction with the hot road surface will highlight any flaws in the short term.

We recommend the best product in our experience for your fine automobile based on decades of experience and know how.

SL65 AMG Mercedes Engine Mount

There are many things could go wrong on a high performance automobile.

SL65 AMG MercedesClick on the image to view bigger photo.

Here is a perfect example of a Mercedes SL65 AMG broken engine mount, which is quiet common on this vehicle due to the powerful engine and the compact size of the engine mounts.

The driver side mount has been broken into two pieces, became two halves as the twin turbo V12 engine tore it into two under load .

These mounts are hydraulic fluid filled when new and will fail predictably after 5 years of driving.

Worth to note! They also collapse as they are being compressed by the large engine sitting on them for 24/7.

Driving or owning a high performance Mercedes and or any other high performance  car, has its cost associated with it.  This is one of them and needles to say it’s very important to have this fine pieces of engineering being inspected and maintained by qualified senior technicians regularly.

Knowing what to look for on this special build cars is half of the battle as decades of experience working on this cars reveals the known issues with them.

This is ever more important to find a real specialist where the decades of expertise will pay off instantly.

SL65-AMG Mercedes engine mountAnother view of broken SL65 AMG Mercedes engine mount  at left .Click on the thumbnail to view bigger photo.

This is a perfect example of issues caught in time before the monster engine would tore into pricey components and in turn perhaps destroy the hood and everything in it’s way in the engine bay if driven spiritedly.

We also replaced the active body control hydraulic lines as well at the same time and naturally performed a 4 wheel alignment when all has been put back together.

Let’s not forget, the 2 front ABC struts has been renewed, the ABC filter and fluid has been refreshed, so it will be ready for the oncoming driving season.
