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…!
W
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 280SE 3.5 ute, brakes and air con overhaul
The booster was a bit rusty looking so i t has been decided to strip it down. and clean it up .After pulling the master cylinder off,it could be seen that the booster was full of fluid….. 
as can be seen ,the booster contained close to 3 liters of brake fluid.
t
The steering column was then pulled and examined,more BiCarb! ,and the paint had been attacked and needed redoing . 
This picture shows the extent of the biCarb inside the gearshift mechanism.
Under the booster,the firewall and the right front chassis rail join was rusted out . The rusted metal is removed and replaced with fresh metal.
Nest Job was to rebuild the Air con and once the housing was opened up,it could be seen that the evaporator was full of fluff and BiCarb.
The bottom of the evaporator housing was rusted out so a new peice of Zinc anneal was welded into place to repair the bottom .Condensation won’t leak into the car now,.
the evaporator has been flushed and the fins cleaned and straigfhtened .Once the new bottom was welded in ,the housing and panels were zinc primered,then primed and fisnh coated in black .The foam liner was replaced and the unit reassembled and the fans tested .
