KE Jetronic EHA Adjustment

I discovered at the MBCNSW Dyno day that my 560SEC was running dangerously lean. Lean enough to cause damage to the engine. While I was in the USA for work, I went to the Mid Florida Auto show. I met Pierre Hedary there (who runs an independent Mercedes workshop), who suggested that I should start […]

MBCNSW Dyno Day

The MBCNSW held a tech day at a dyno equipped performance shop today. I was keen to attend as I wanted to understand how much power my ECE 560SEC is making. Geting dyno time independently can be expensive, but through the club day it was very affordable. The tech day was held at SR Performance […]

NSW Historic Plate Adapter

It was just announced that the NSW 60 day logbook ‘trial’ has been made permanent. This is great news as its a really good system. The two minor drawbacks – the amount of paperwork and the size of the plates. The plates are tiny and really ugly. They are so small that they don’t line […]

M117 lower oil pan replacement

One of the things I noticed when I first changed the oil on my 560SEC was the dent in the lower oil pan. Presumably it hit a curb or rock at some point. It was also leaking. the dent was likely too small to interfere with the oil pump, or oil pickup but I wanted […]

Mercedes self-leveling rear suspension flush

A common feature of Mercedes cars from the mid 70s through the mid 2000s is the self-leveling rear suspension. This system is standard on the wagons, but was commonly specified on the higher end sedans too. Mercedes-Benz Australia was particularly keen on the system fitting it to coupes and even mid size saloons.

The system […]

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. […]
