Hindustan Ambassador Cylinder Head Removal | BMC B Series Head Removal
In the last video we tested the engine for valve and piston ring leakage. Following the diagnosis, in this video we take off the cylinder head in order to decarbonize and rebuild the cylinder head.
The goal is to get this HM Ambassador Mark 2 back on the road asap without undergoing a complete engine rebuild (cylinder head overhaul and new piston rings maybe).
The leak down test conducted in the previous video revealed that the valves in all cylinders were leaking. The only way to fix leaky valves is to take the head out, and lap the valve to the valve seats (provided the valves and seats are in a good condition) so that they seal the compression inside the cylinder. This video is pt2 in a series of videos to get this 1970 Ambassador Mark 2 back to health. The procedure for taking the cylinder head off demonstrated in this video could be used for all generations of the Hindustan Ambassador: the Mark 1, Mark 2, Ambassador Mark 3 and Ambassador Mark 4. The lineage of the Amby being so, the same process would work for the BMC B-Series engines on MGB, MGA and other British classic cars.

History of the Ambassador: The Hindustan Ambassador's roots can be traced back to the Morris Oxford Series 2. In the late 40's, Hindustan Motors or HM entered an agreement with Morris Motors to manufacture and sell the Morris Oxford, Morris Minor etc. as the Hindustan 14, Baby Hindustan etc. With the passing of time, came the Morris Oxford Series 2 sold as the Hindustan Landmaster and eventually the Morris Oxford Series 3 that became the mighty 1957 Ambassador (unofficially called the Mark 1). The Amby in this video is a Mark 2 which was a facelifted version of the Mark 1 (with a Mini like front grille) and in our opinion, the first desi Ambassador (cause it was not a through and through copy of the Morris). The engine however, was the same up until Ambassador Mark 3 and Mark 4 (we believe): inline 4 cylinder petrol BMC B Series.
The BMC (short for British Motor Corporation) B Series, also known as the MG B Series engine powered a LOT of cars back then, including sports cars: MGA, MGB, Morris Mini, TVR Grantura, and a few Austin and Wolseley cars too.
