W126 Bonnet insulation

All W126 models have an insulation pad under the bonnet to protect the paintwork and reduce engine noise. Over time, the W126 bonnet insulation degrades and starts crumbling down onto the engine. At this point most owners simply remove it.

I own two W126 models with the remnants of their insulation pads. A few months […]

The 560SEC has stopped smoking

My 560SEC had a problem where it would emit a puff of smoke after idling. This was rather embarrassing taking off from the lights. It did give me the advantage of keeping people back who got too close. My assumption was that it was cause by old valve stem seals. As the seals get old, […]

560SEC Timing chain and valve stem seals

The Timing chain replacement is almost finished on the 560SEC. The new chain is installed, guides fitted and valve stem seals replaced. I stopped by the workshop to pick something up that I had left in the car and I was able to see it almost done.

The photo shows the new chain in […]

560SEC fuel leak

When I last used my 560SEC before Xmas, I noticed a rather large puddle of petrol underneath it. I’ve not driven the car since as it is rather dangerous to drive with such a leak. I had assumed it was probably fuel hoses. Many cars run on E10 rot their hoses. I purchased a few […]

560SEC Upcoming Projects

I’ve been preparing for the next round of improvement projects for the 560SEC. The most important is the Timing Chain and Valve Stem seals. I’m not going to do this job myself and am hoping to save a little labour cost by having both the stem seals and the chain done at the same time. […]

560SEC Major Checks

My two biggest concerns buying this 560SEC was the potential for rust being a UK car, and the condition of the timing chain. I was pleasantly surprised when I looked underneath the 560SEC and found that it was not a rusty car.

The other common W126 rust area is under the rear windscreen. This is […]

New alloy wheels for the 560SEC

My 560SEC came with a set of Simmons wheels. These wheels are not to my taste and were too wide for the car. The wheels had been mounted with spacers which I do not like. On Thursday, I secured a great set of 15×7 Mercedes wheels which I fitted to the 450SLC. This meant that […]

Road trip to MB Spares and Service

My 560SEC came with a set of aftermarket wheels from Simmons. The Simmons wheels are a locally made wheel, and this set are two piece 16″ variants. They are shod with 245mm tyres so the fronts rub on sweeping corners and the backs on higher speed bumps. I prefer a more stock look so the […]

560SEC Improvements Part 2

Today I continued working on the 560SEC. I gave the car a quick wash to get a better sense of the condition of the paint. Overall it is pretty good for its age, with the usual minor chips and scrapes here and there. The worst is a small amount of damage on the passengers side […]

560SEC Improvements

I spent the afternoon going over the 560SEC, making small improvements and evaluating the car. The first order of business was to look at the original factory wheels that came with it. As was the norm back in 1987, there are five factory alloy wheels. They were in a really sorry state when I removed […]
