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.”

The Importance Of Antifreeze/Coolant Service
Take a look at these photos, notice the brown areas of clogging and material at the bottom of the radiator? Nowhere is this more frequent than on engines using an aluminum cylinder head, and cast iron block…like most modern cars.

And we also find this clogging not just in radiators, but also in heater cores. A heater core is a radiator-like device used in heating the cabin of a vehicle. Hot coolant from the vehicle’s engine is passed through a winding tube of the core.
Fins attached to the core tubes serve to increase […]

By | January 8th, 2021|Categories: Case Studies|Tags: , , , , , , , , , , , , , |Comments Off on Land Rover Evoque – Engine Problem With Timing Chain Sprocket

The Problem
This Land Rover client presented us with a 2015 Evoque with a Check Engine Light (CEL) on, and noise from the engine.

On inspection, our Land Rover technician verified that the CEL on, and carried out a visual assessment. Then using the diagnostic computer we checked and scanned for codes. We found the following fault codes, P052A – Cold start camshaft timing over advanced bank 1, P0011 – Intake camshaft position timing over advanced bank 1, P0341 – Camshaft position sensor A circuit/range performance bank 1.

Fault codes are only a starting point, we never […]

BMW and Mercedes Benz – Ceramic and Aluminum Fuse Problems – How and Why

By | November 10th, 2020|Categories: Case Studies|Tags: , , , |Comments Off on BMW and Mercedes Benz – Ceramic and Aluminum Fuse Problems – How and Why

About The Problem
One of the more common electrical issues we see with the vintage Mercedes vehicles are problems related to the fuses and fuse box. Like many of the older European models, these cars were designed and engineered with identical or similar parts, in this case, the ceramic and aluminum exposed fuses. At the time, this was an excellent solution, but now, some 20 years later, we frequently see a series of pattern failures on vintage Mercedes, and almost always the same issue over time: fuse failure. While the ceramic and aluminum fuse failure is particular to older European vehicles; however, it’s a simple problem to fix in the […]

Mercedes Benz Intake Manifold Problem Explained, And How To Correct It

By | July 15th, 2020|Categories: Case Studies|Tags: , , , , , , , , |Comments Off on Mercedes Benz Intake Manifold Problem Explained, And How To Correct It

Many owners of late-model Mercedes-Benz cars equipped with 3.0 and 3.5l V6 engines (M272 or M273), as well as some of the later V8s, have or will likely soon experience a near-universal Mercedes Benz intake manifold problem.  Generally, we find problems in performance, which include poor idle, loss of power, and a Check Engine Light.

The Mercedes Benz intake manifold problem is caused by one of the inlet manifold tuning flaps breaking, causing unexpected and deficient performance depending on the orientation of the flap that has broken.  To review the system, let’s describe what the Mercedes intake system is doing and […]

By | July 3rd, 2020|Categories: Case Studies|Tags: , , , , , , , , , , , |Comments Off on Jaguar Engine – Broken Timing Chains, Bent Valves

Problem
This is an excellent example of what you do not want to see happen to your Jaguar, you’ll note the broken secondary timing chain, and consequently the damaged engine valves.

On the early XK8 and XJ8 Jaguar vehicles, there is a known flaw in the upper timing chain tensioner. What happens is that the chain tensioner fails, causing the chain to slip or completely break like you see here, causing damage to the valves.

Symptoms
A noticeable engine noise while idling or during a cold start can indicate a timing chain tensioner problem. The engine noise may […]
