Under Seal

Our 1964 Mercedes 230SL has been in the experienced hands of classic car technician Steve. He cleaned up the loose sealer and surface rust around the rear arches and the rear chassis rails before applying a new coat of under seal.

New rear wheel cylinders have now been fitted as the old ones were corroded and seized. The front brake callipers have both been stripped down, cleaned, and new pistons and seals fitted as the old ones were corroded and very stiff in operation.

1964 Mercedes 230SL Appraisal

Steve has carried out an appraisal on our Mercedes Pagoda to report back findings to the customer.

Meanwhile John is attending to a leak on the gearbox. It seems to be coming from the gasket so the sump pan was removed, filter cleaned and a new gasket fitted.

230SL Cold Starting

John has made and fitted new down pipes to our 1964 Mercedes 230SL. This is because the old ones had to be cut off as they had seized. New baulk head sound deadening was fitted before John investigated the non-starting issue. He went through the wiring and traced the fault to the timer relay on the inner wing. He adjusted the gear linkage and inhibitor switch so the car starts in the correct lever position.

230SL Engine

The engine of our 1964 Mercedes 230SL has made fantastic progress and will soon be reunited with the car.

As you can see from the photos below, the engine is in the final stages of assembly.


Engine Bay

Our 1964 Mercedes 230SL has been transported back to the workshop in preparation for its engine work to continue.

Its engine bay has been looked at as the engine continues to make progress at Coltec.

More Progress

The head of our 1964 Mercedes 230SL has been refaced.

The block has been bored and honed and the deck has also been refaced.

Almost Ready For The Rebuild

With the new parts starting to arrive, it is almost time to begin the rebuild of the engine of our 1964 Mercedes 230SL.

The fuel injection pump and injectors have been rebuilt and are ready to be refitted. The camshaft is currently at Kent Cams where the camshaft is being reprofiled to the original Mercedes specification. This is because automatic gearboxes don’t respond well to uprating.

The camshaft and new cam fingers should be ready next week when more progress can be made.

Engine Progress

The engine of our 1964 Mercedes 230SL has continued to make good progress. The reground crank is now back and the required parts are on order.

Once these arrive, we will begin the rebuilding process.

Engine Investigation And Rebuild

The investigation and rebuild of the engine of our 1964 Mercedes 230SL has now begun.

Cam wear was noticed and the cam chain was stretched. The tensioner for the cam chain was also worn, as were the bores. The injection pump and injectors will be serviced while the engine is out of the car.


The crank will need grinding and the cleaning process has begun.


It was also noted that one of the pistons was facing the wrong direction and was cracked. As you can see from the videos below, the bearing in the rod has failed and is the cause of most of the noise when the car is running; and the bearing has moved which has blocked the oil feed hole and then started to break up.

Collection And Back Into Storage

Our 1964 Mercedes 230SL was collected from our friends at Coltech earlier today,

Tony and Nick made the trip, loaded up this beautiful classic and safely transported it back to our secure storage facility.

It is now safe and secure surrounded by other classics currently in storage at The Hangar.

Mercedes 230SL – possible engine rebuild

Arriving in with us this week is our 1964 Mercedes 230SL. The car has come in for a possible engine rebuild but at this stage we are not convinced that this work is required. We want to carry out a few tests and checks before we make the decision of whether the engine needs to be removed.
