I'm not doing much with Goldie recently, due to lack of time to get her out of the garage, but the last two jobs I've done were mixture, timing and idle adjustment and replacement of the ignition ballast resistors.

As for the mixture, she was running a bit rich and CO was at 2.04%, idle at 700rpm. After adjustment, CO is at 1.4% (it was fluctuating between 1.37% and 1.43% at idle, actually), so maybe a little too lean this time? We've set idle back to 750rpm, but surprisingly the idle adjustment screw is maxed out - possible air leak somewhere on the intake path?

Either way, we've cancelled out the 3* timing retard I had originally setup to run on 95RON as I've found out recently the E5 fuel in Ireland is at 97RON these days. She's setup for 98 as per factory spec now, and I'm using an octane boosting additive to account for that last missing one ;)

The ballast resistors were still factory ones, but I've spotted last week that the 0.4 Beru has developed a hairline crack along the body. I've replaced both on principle, with genuine Bosch parts. Funny thing - both the original and replacement resistors read +0.2 Ohm above their rated value (0.6 and 0.8, respectively).

I'm taking her on another road trip across Europe over the next fortnight, so that'll add another 5k or so Autobahn kilometres to the clock.

In the meantime, my W124 is the go-to car for getting my hands dirty. So far I've replaced the throttle body, radiator, water pump, spark plugs, AC condenser, rebuilt the headlight wash/wipe motors, serviced the diff and tranny... and it's running as my daily, at 200k miles :)

I drove about 15 miles this morning to go have breakfast with my daughter and when I arrived I realized that after I turned the key to shut off the ignition, the car was still running. So I opened the hood and pressed the engine shut-off button to shut the engine off manually. When I returned to the vehicle to drive home about 20 minutes later, I unlocked the door and all the doors unlocked immediately. My doors haven't worked for over a year and every time I shutoff my car, I only had about a minute before I lost all the locking vacuum. I was amazed to say the least!

So I drove home and the engine still wouldn't shut off. I opened the hood and inspected the vacuum lines and when I wiggled the brown vacuum line going to the shut-off valve on the back of the IP, the engine immediately turned off! I looked at the small piece of vacuum tube and it was swollen and soft and had seen better days. I had some extra tubing from one of my door lock diaphragms that I'd replaced a few months ago, so I replaced the old one with that. I started up the car again and after a minute I turned it off and it shut off instantly. I just tested the locks after 45 minutes and all of the locks popped up quickly and then sucked right down again after locking. Even the fuel door is staying locked! It used to re-open after about 30 seconds even after replacing the entire assembly a few months ago.

I am very happy to have it all working again and the fact that all it took was the replacement of a simple tube, makes me even happier! Great success!

I learned after replacing the rubber vacuum hose connected to my vacuum shutoff valve, that there was oil on the hose meaning that the shutoff valve was on the way out. I ordered the part from my dealership, but since I'm cheap and have another baby on the way, I went the cheap route and installed an in-line filter. This way I'll know if oil is being sucked back into the vacuum system before it makes it into the ignition. I've heard of oil being found in the trunk diaphragms! The filter is definitely a little larger than I though, but it will work for now.

I have switched the Bosch carb with a Holley. Man what a difference! Runs really smooth and easy to adjust! And Since I am not a purist, I like the way it looks with the Holley airfilter, since you can see the whole engineblock now. Just a few minor details to sort out and I can have the car back on the road after 6 years in the garage.

The 6.9 was feeling a little bouncy...over the last few drives seemed to get more and more bouncy.  Replaced all 5 spheres/accumulators. (first time since I've owned it for four years)

WOW!

Feels soon good! What an awesome drive.
