1976 Mercedes 350SL

Always Learning – Handing over our 1976 Mercedes 350SL to a marque specialist

The story with our Aztec Gold 1976 Mercedes 350SL continues but this time at marque specialist Derrick Wells.

After looking into the starting issues that we have had with the car since it came over to be with us at Bridge Classic Cars from Ireland, our in-house technicians thought it best to get the opinion of a true singularly focus specialist.

As you may have known, we bought this car on the understanding that it was in good aesthetic and mechanical condition. That didn’t quite turn out to be true… sometimes you do have to be careful with what you buy even with a car such as this.

As soon as we get an update on the car then expect to see that right here on Bridge Classic Cars.

Investigation work continues on the Mercedes engine…

Ady has been investigating the engine on the 1976 Mercedes 350SL. Initially we were lead to believe this to be a running car but unfortunately it has arrived with us as a non-runner, and he’s found that this is probably due to an electrical fault.

There are two sides to the V8 engine and only one bank works. the right hand bank looks to have been tampered with.

The wiring to the injectors on that bank have been cut and rewired to earth. We don’t understand why someone has done this unless they are trying to cover up something more. There would be no other obvious reasoning. Rewiring to earth could possibly mean the engine can still run, albeit on 4 cylinders as it will hopefully not be sending any fuel into the ‘dead’ side. If it has then we have a problem.

We have replaced the points and adjusted the timing but the car remains on 4 cylinders.

We have then removed the plugs and checked the condition of the number 6 plug which looks to have a carbon build up. We have checked easy access compressions on all cylinders.

We have refuelled the vehicle but as before, the engine can only run on 4 cylinders and is therefore running dangerously rich.

Mercedes SL350 Electrical Issues

Not the results we were expecting but our 1976 Mercedes SL350 has arrived. This was presented to us as a much loved, beautiful example of the iconic R107 Mercedes SL. Aesthetically speaking, the car is beautiful but our workshops will need to dig a little deeper as we have some underlying issues that need to be addressed.

Unfortunately we have been unable to get the car running. Upon further investigation the car is only running on one of it’s two bank V8 engine. We believe this is due to a wiring issue. Our auto-electrician will hopefully be able to find the fault and hopefully it won’t be too big a job!

Aztec Gold Mercedes coming this way!

Another car which we have recently purchased is this 1976 Mercedes R107 350 SL. With the exterior of the car painted in Aztec Gold and the interior being Chocolate Tex colour, it screams the 1970s. The exterior of the car is in great condition and with the seats being made of vinyl, they’ve done extremely well with the age of the car. In terms of the engine, the vehicle has been kept very original but has had work done to it in the past couple of years. Watch this space to find out when it’s made its way to our workshop!
