Engine Rebuild Timelapse

Sit back and relax whilst you watch a full timelapse of a Classic Heritage Aston Martin DB6 engine rebuild by JMB Services. This process involves the rebuilding of the engine block starting with checking the oil clearance for the crankshaft, followed by fitting the pistons to the conrods, and then inserting into the block. The timing case is then built up with new chains and tensioner. The sump area is then fitted with the oil strainer and baffle plate which is then followed by fitting the sump and lock wiring all the bolts. The cylinder head is the next to go on, which has already been fully assembled ready for fitting, the camshaft timing is then carried out. Carburetors are the next thing to go on then close the engine up and fit all ancillary parts ready to go for Dyno testing.
