My idle is about 500 in drive and even hot the oil pressure is around 2 to 2.25 Bar. I am using horrendously expensive Red-line 20-50 but it hasn't used a drop in the year I have owned the car. My car rocks a bit on idle so I might raise it a bit to your 650 in drive and see what happens. I...

When setting up correct valve clearances in M100, and M117 motors with hydraulic compensators the manual calls for the use of tool 117 589 03 61 00 for 117's and tool 100 589 04 23 00 for M100's which is a simple dropping pin in a support structure. Does anyone have the specifications to make...

Had a day to get a few fluids changed for which I have been preparing for a while. 1) Unsure how old brake fluid was so changed brake fluid for M-B Dot 4 plus. 2) Changed fluid and filter in power steering - probable wast of time as both seemed fresh and clean albeit pink and not the correct...

Having read S Classes epic struggle he mentioned a "MacGuyver" power brake bleeder which I assume means a home made or in my parlance a "Heath-Robinson" bleeder. This led me to think that I might be able to use my radiator tester with internally expanding bladder to seal at the top of the...

The old battery in my 450 (From my wife's previous 163 ML - 6 1/2 years old) finally died and refused to take a charge this weekend so I decided my 6.9 needed a new Mercedes Battery with original stickers etc and it's present perfectly good one transferred to the 450. I came home after a half...

I will be replacing the gearbox output seal as it has a small leak and the front flex joint has oil on it. All procedures I can see seem to show that the whole driveshaft has to be removed and if this is the case I wll replace the rear pinion seal as well but is it possible to only remove the...

Hi Des, Here is the standard aircleaner in the first photo. And here is the second photo showing the 560 aircleaner with the right horn (left side of the photo) sitting on the airconditioning hoses. I think the LHD runs the hoses low down on the left side of the motor more like the 450...

A post on the M-100 site yesterday about re-siting the battery in the boot for an LPG installation in a 6.9 led me to again contemplate using the twin intake 560 aircleaner and ducting that is gathering dust in my shed. It is not difficult to mount the battery in the boot, arrange an earth and...

The following tool is used to press the steering ball joint from the steering spindle on 123's and 126's. The picture on the ebay web site demonstrates how it is used Konik Tools E-bay Store I contacted the seller and asked if it was also suitable for a 116 spindle but he did not know and...

With a spare couple of hours tonight I hoisted the 6.9 and decided to install the front bushings in the rear subframe. I am also going to do the semi-trailing arm bushes but not tonight. Here are the "before" pictures showing the right front rear-subframe bush in tension and compression and...

Without wishing to be a Glass of cold water at a pissup what are your bearings like. I know with Porsche experience that if a watercooled Porsche mixes water and oil you are expected to change the big-end bearings. They make no mention of the mains because it is a much bigger job and in a 6.9...

THankyou for the pictures Styria - what a brilliant collection of photos. Was it a head gasket leak or is it a crack in one of the heads? Bill

Anyway - the correct term is the cruise control actuator. As you can see from the picture it is not a vacuum fitting but screwed onto the assembly with a plastic nut. It is possible that the other end just fitted into a sleeve in the heater intake ducting but I couldn't find a nipple...

On a rainy Sunday morning I decided to tackle a squeaky low speed fan noise. While poking around I came across a large black vacuum line that looks like it was connected somewhere in the past but is now sitting free. The other end connects to a screwed fitting on the Cruise control modulator...

Hi Styria I have been away for a few days and on returning home today realise I was incorrect when I said Lithium Grease. I withdraw the Lithium grease statement and change it to Zinc Oxide Grease as used on doorlocks. It seems to be about the same thickness and similar lubricating qualities...

Finally got my 6.9 back on the road today with the air-con re-fitted (but not pumped up yet), driveshaft repaired and re-fitted , new 300K AMG replica speedo ( which is actually really good because I can now see up to 120k through the small wheel ) and new timing chain and tensioner. End...

Hi Des, I wandered down to the lobby and asked the Concierge about the Phantom 2. He said it is in England for some refurbishment. Here is a photo of the model which unfortunately is behind glass and I had to angle it from the front to minimise the reflection. Apparently, apart from bing...

Dropped my Axle off at The Star Shop today and went away for an hour or so. Herbert has the exact tool shown in the thread and when I came back it was all finished. Here is the result. Bill

Here is a synopsis of replacing a 6.9 timing chain as I performed yesterday. It does not include any discussion of the tensioner which is peculiar to the 6.9 and which I will photograph and display in another post in the future. I also did not change any sliders as in the 6.9 unlike the M116/7...

Today I removed my camcovers, alternator mounting bracket, plugs and leads and then removed the chain tensioner. I had an original chain so ground the ends off a link with my Dremel and then connected and pulled through a new M-B genuine chain (Chain and tensioner purchased from the Classic...
