Case Studies – Our Service Solutions

A Collection of the Odd, Unusual and Interesting Found While Servicing our Client Vehicles.

Originally intended as a showcase for customers of our workshop and staff’s abilities, this page has evolved in an interesting and informative teaching tool, and one of the most popular pages on our site!

By nature, these are rather extreme examples of failures, and not what we typically find during service. Our goal at Atlantic Motorcar is to prevent these from happening to you and your car. But rest assured, if we can fix these challenges, regular maintenance is breeze!

We like to call this our “YES WE CAN!” page. You can also view many of these concerns on our Facebook page. Each photo can be enlarged by clicking on it.”

Tire Wear – Tire Cupping, Causes and Correction

By | January 6th, 2020|Categories: Case Studies|Tags: , , , , |Comments Off on Tire Wear – Tire Cupping, Causes and Correction

What Does Cupping Look Like?
Tire cupping is an uneven wear pattern, which occurs due to irregular up-and-down motions of a wheel (bouncing). It interferes with the proper contact of the tire with the road, scooping rubber in spots.

When it comes to your tires, cupping is a bad sign and typically means you have other problems with your car that are affecting your tires.

The term “tire cupping” is unfamiliar to many drivers, but it’s a problem that happens more frequently than you’d think. Cupping, also known as tire scalloping, refers to when a car […]

Why An Oil Filter Housing Leak On A BMW Engine Shouldn’t Be Ignored

By | December 13th, 2019|Categories: Case Studies|Comments Off on Why An Oil Filter Housing Leak On A BMW Engine Shouldn’t Be Ignored

What Happens
Oil leaks on any engine are both a nuisance and fact of life but few can cause damage like the BMW oil filter housing gasket.
I haven’t seen too many higher mileage BMWs that don’t have some kind of oil leak that goes without repair. The N 54 and series of engines have been excellent, and very durable, once the oil leaks are handled. However, they are not engines that do well when the oil leaks are not promptly and professionally addressed.

If there’s one oil leak on these engines that is critical to address, it’s the oil […]

By | December 8th, 2019|Categories: Case Studies|Tags: , , , , , , , , , |Comments Off on Volvo Trailing Arm (Rear Control Arm) Bushings – The Correct Repair

The Problem
We often come across 2008-20015 Volvos that come with for concerns of excessive tire wear, or “loose handling” issues. Often the customer has been at other shops and paid for multiple parts, repairs or alignments in an attempt to correct the issue. Yet it remains, and the car is then referred to our facility for evaluation.

What Happens
Almost invariably we find that the rear trailing arm bushings, a rubber and steel mount, and the only part that secures and locates a critical part of the rear suspension system to the body (attaching to the […]

Porsche Water Leaks and Electrical Problems – Drains Aren’t Just For The Sink

By | November 5th, 2019|Categories: Case Studies|Tags: , , , , , , , |Comments Off on Porsche Water Leaks and Electrical Problems – Drains Aren’t Just For The Sink

Drains aren’t just for bathtubs, or the kitchen sink, they also exist in your car to drain away from the effects of rain, ice, and snow. Yet, they’re one of the most neglected of service items. Often considered only when it’s too late.

The Problem
If your car has persistent condensation in colder weather and damp mildew smell, chances are that the foam pads in the footwells and on the floor behind the seats are saturated with water. A cursory check will confirm this for you: have a feel around the join of the floor carpet […]

How to Fix Squeaky Brakes

By | October 15th, 2019|Categories: Case Studies|Tags: , , , , , , , |Comments Off on How to Fix Squeaky Brakes

What Causes Breaks to Squeak?
Don’t expect brakes to be totally quiet—sometimes, they’re going to make some noises. Don’t panic, because a squeaky brake can stop a car just like a silent one can.

What causes the squeal? Modern brakes use a cast-iron disc squeezed between two brake pads lined with friction material. Under the right conditions, the disc, the pads and the caliper they’re mounted in can start to vibrate—in exactly the same way a violin’s string vibrates when stroked by the horsehairs on the bow. Most brake squeals occur at a single discrete […]

Mercedes Brake Line Repair – Rust Damage

Mercedes Brake Line Repair – Rust Damage
If you look at this late model Mercedes, you’d think that it hardly would have a problem with rusted brake lines, a safety issue that has afflicted domestic cars for decades, but until recently, was quite rarely seen on European autos.

Why This Happened
We’ve seen the transition from the older bonded phosphate brake lines used on the European cars that never rusted, to painted lines. We’ve found that the painted lines are much more susceptible to cracking the coating and then rusting the exposed metal.

But knowing where to […]
