The new engine and trans are installed with a new oil pan ,rear and front crank seals. New injectors with new intake manifold gaskets,timing chain and rails should see a nice reliable tow car for the owner 🙂 .New fuel hoses and clamps will connect the fuel system together .

In these  pictures of the distributor, the inside is full of the damned bicarb which was used to strip the older paint of the cars body before painting.

The distributor will be stripped and overhauled because the bicarb will affect the fuel injection trigger points which are in the lower part of the distributor.

IMG_0334In this picture it can be seen that the bicarb has infiltrated the igniton wiring.

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….. IMG_0137 IMG_0139as can be seen ,the booster contained close to 3 liters of brake fluid.

The steering column was then pulled and examined,more BiCarb! ,and the paint had been attacked and needed redoing . IMG_0142 IMG_0143

IMG_0145 IMG_0146 IMG_0149This 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,.IMG_0168 IMG_0169the 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 .

Weber DCOE rebuild

Leave a reply

I’ve been restoring a 190SL for an owner and part of the task involves rebuilding it’s non standard DCOE carbs. A lot of W121’s were fitted with these over years to get around the problems thrown up by the awful Solex side draft carbs originally fitted.

Borgward Isabella Solex Carburetor

i was asked recently if i could overhaul this Solex twin down draft carb. It’s a 32 PIAATA the same as found on Mercedes 220Sb W111 models of the early 1960’s. This one was making the car hard to start. Everything appeared normal on strip down but it’s missing a vital part,a valve in the accelerator pump.I’ve given the housings a clean while waiting for the gaskets to be delivered.

There is also a special adapter for the Borgward manifold .

Wet blasting of alloy engine parts.

Leave a reply

First developed in England in the 1940’s,this is a process where water and compressed air is used to clean delicate parts and restore the finish to an ‘as new’ surface. Also known as vapour blasting or slurry blasting  ,it is almost a green process as no caustic chemicals are required to remove dirt and oxidation .

Pictured are a pair of Porsche 928 cam boxes (yes i will work on any quality car!) . the lower is a ‘before ‘ example with burnt on oil and badly oxidised surface. The above it is an example of the finish achieved by just cleaning. next pic shows a 928 cylinder head as removed ,again very oxidised . Thwe 3rd picture shows the bare heads,all clean ready for valves ,springs seals etc to be fitted.

Feel free to call about your parts restoration and what i can offer.
