W112 Mercedes 300SE Lang ( Long wheel base)
All the way from W.A is this horizon blue 300SE with some serious rust problems. Not so unusual in a finny but serious enough to require a lot of work to rectify.
left rear Jack point has basically rusted right away,as someone has found in the past when attempting to lif the car .
Right
i
Left rear boot box floor ,a normal rust spot and no worse than others .
Rear box section ,no seriouis rust outs.
Right front chassis strengthening member rusted out . Rain water gets inside this section and if the lower drain holes are blocked,they eventually rust away . This particularly bad as that is the air cleaner visible in the center.
Inner left boot box side .
inner left rear chassis mount.
Left rear anti dive link mount
Inner side of left front sill section .Showing sever rust. this will all be replaced .
Steel spring installation where the air springs have been removed .
Mercedes Benz 250S for sale.
250 S in very straight condition. Been off the road since 2010 due to a minor fault. This is a project car and will require normal work to get registration etc . There is very little rust in the right front sill front and the rear boot box bottom,right hand side. 
No rust in the doors or floors!! no dash cracks ,and the MBtex seats are still very good. Original boot mat is in very nice condition . 
Mercedes Benz 300SEL 6.3 restoration Project
This is RHD 6,3 #2206 . The engine is incomplete and the drivers side sill/rocker is rotten but the rest of the car is surprisingly sound but in need of a full restoration .RHD 6.3’s are too rare to part out and i would rather restore this car anyway….. or build a historic racer for weekend fun.
A great score!
For my own 6.3 I needed a new radiator and had thought of eitherr making a newer one out of alloy but then i found this on ebay..
A brand new old stock 6.3 radiator for . Not $5000 AUD , Not $2500 USD as demanded for a new one but …………. $275. Still in it’s original box.

A short video showing the 6.3 up and running to check it’as C/O level at hot idle .
300SEL 6.3 progress…
The engine is now together and just needs tuning , after the heads were checked an the tappets adjusted.
The shroud was derusted ,then painted with POR15 gloss black .
Mercedes Benz 300 SEL 6.3 cylinder Head swap.
A new fuel line has been fitted using the original brackets etc which were in good condition after 40 years…!

The engine bay needed a clean and after a wash it was revealed to have a few places where the paint had disappeared because of engine heat . 
With the heads off ,a few little things became apparent such as this feed wire for one of the thermal time Switches. A couple of the firewall grommets needed replacing .Missing grommets allow noise,fumes etc into the cabin .
The Steering box was leaking through that round part on the top part of the
Steering box . A new seal had to made for this and the two copper washers were missing. the cover nut and lock nut were both loose. The oil return pipe on the steering box has also been damaged in the past when some one bent it.
With the heads off and the engine due for a repaint ,the booster was removed and rust removed . it was then etch primed and primed. The other objects in the picture belong to the 280SE 3.5 ute project..
The car was completely masked up and the engine bay resprayed in the black satin as before.
BUT before the black could be applied and the engine bay was still in primer one or two other jobs need doing.
The firewall brace on the left hand side was cracked almost right around and had to be welded up.
With the engine bay now painted the heads were fitted ,along with newly plated relay brackets . There is a lot less wiring now the original loom has been cleaned up and things such as a mobile phone loom removed .
Mercedes Benz 300SEL 6.3 repairs
OK, ,more progress on the 6.3. The fuel is being replace and this pic shows why. Many years ago someone has crushed it by lifting the car incorrectly with a hoist ,jack or….forklift. In fact it was squashed in many places.
next pic shows one of the other crush points.
Next job is the Fuel lift pump.
As can be seen in the pic,the pump was mounted solidly and is 150mm too high,meaning that once the fuel level drops to 1/3rd tank level the pump was starting to starve for fuel . These pumps are not a suction pump,but a pressure pump.
6.3 300SEL Service
Little details..
This is the conduit where the vacuum lines for the central locking pass on the 280SE 3.5 Project… pretty neat and an example of the over engineering on Mercedes of the past.
The 6.3 was misfiring badly under acceleration. a big disappointment for the owner ,who had spent a lot of money getting the injection pump rebuilt and the ignition converted to electronic . So, when working under thecar replacing worn rubber joints and worn drive shaft parts I spotted the squashed fuel line .The picture on the right shows a really bad dent in the main fuel line . The entire line will have to be replaced ,and i am thinking this is probably the cause of the misfire
The Drive shaft with it’s new staked unijoints and rubber center support bracket .
