1934 ROLLS-ROYCE 20/25 ENGINE REBUILD

Here are a few photos of the Rolls-Royce 20/25 engine as we were building it back up. 

It is now back in the car and running well on test.  We will put a few miles on the car before it is returned to its owner and then it will come back to us for a 500 mile service.

1935 3 1/2 Litre Derby Bentley

 During investigation of the cooling problems this car was experiencing, we removed the side plates to inspect the waterways and the visible areas appeared free.  Using our bore-scope we were able to see further into the hidden areas where it became apparent that there was a great deal of corrosion and debris blocking the water circulation around the push rod side of the cylinder block.
This has all been cleaned out and new copper tubes inserted.  Raymond is now lapping in the valves before putting the engine back together.


Side plate removed from block showing some corrosion although
water was still able to circulate (small gap visible on left).
Main corrosion found on opposite side of block out of sight

MORRIS 1000 VAN

This van has recently had a re-spray and bodywork with one of our colleagues.  We were then asked to give her a service and MOT as well as check the compressions since she was not running particularly well. 
Upon checking the cause became clear since the valve guides on the 'refurbished' engine already in the van had not been fitted correctly meaning that the valves had been badly worn.  New valves and guides were fitted and the head was skimmed before the re-assembly.

JAGUAR E-TYPE 1969

The cylinder head has returned from the machine shop and has been re-assembled.  The valve clearances are all set and the head has been re-fitted to the block.  Graeme is currently fitting the inlet and exhaust manifolds.

Having originally been in the USA, the car has an elaborate emission control system fitted.  This is now being removed and the manifold modified to suit.
