What have you done for your W116 today?

[Jan S]

I did the return trip this weekend (see previous post). A total of 4.777 km (2.970 miles) since the car left home in May.

A fantastic driving machine, a pleasure to drive.

The fuel consumption for the return trip was 1,55 liter/10 km (15,2 mpg), which is very good and normal I would say for a 6.9 ... more so than 1,41 liter/10 kilometers (16,7 miles per gallon) I measured during the beginning of the trip in May.

A few issues require some attention:
1. Need a new power steering pump (I knew this before I started the trip)
2. Need new headlight bulbs
3. Check the front wheel bearing on the right side ... something is not right (grease has been coming out of the center cap, and traces of grease can be found on the lower parts of the two doors and the rear end of the car. This has never happened before)
4. A thorough wash and polish

Fall/Winter is coming, hence this was probably the last big tour this year.

Very nice consumption    For the grease to come out from under the cap would be unusual as the fit of that grease cap is super tight but I guess not impossible.  Maybe the bearing is overheating and melting the grease into liquid form?  Likely you will have to completely strip out the bearing and have a look but my guess would be the bearing is cooking the grease out.  You can do a quick test after driving.  If the wheel is very hot to the touch after a drive then likely you have a bearing too tight (preload not set properly), or dragging caliper(or both of course).

I love to see these cars being used! That is excellent fuel consumption, your car must be pretty well dialed in to get that after 45 years!

Yes, very satisfied with fuel consumption. Either "well dialed in" (as you say) or something is not right (fuel distribution not properly working, .....)

Yes, agree ... I believe the bearing is cooking the grease. Could it be bearing too tight or too loose? Calipers are relatively new (3 years). I've been on long trips before, but this has never happened before. I will do the test you suggested.

Likely too tight.  Regardless you'll have to strip it out then the correct way is to set the preload with a dial indicator but a lot of people just do it by feel though it takes experience of course.

Regarding the fuel consumption , i think it has to do with the driving in Norway my 6.9 also took around 15 liter per 100 km in Norway , but it also took 6 Hours to drive 350 KM  .
In Germany i usually get 18 - 25 L per 100 KM .

Getting the car ready today for my high school graduation tomorrow, with a good interior vac and light wash. I've spent the past 3 days polishing all the chrome in the car, down to the Becker Mexico Radio I have. Did a really good wash last week, and just neatened it up today, and she really shines. I also fixed a few odd things in the past two weeks, seatbelts, factory trim and screws, headlights, bonnet cable. (I bought a bonnet cable from VenessAuto, the quality of the part is good, but the extension is poor, and the grommet didn't fit well. I ended up utilising some crafty zip ties and reusing the original grommet.)

In a months time I want to tackle the climate control and central locking system. Any tips?
