Hindustan Ambassador Engine Leak-down Test

#HindustanAmbassador
This 1970 Hindustan Ambassador Mark 2 had been sitting for about 3 years. We managed to get it running but it ran poorly, to say the least. The engine significantly lacked power and also consumed oil. Theses symptoms led us to investigate the head and piston rings for leakage, the process of which is demonstrated in this video.
History of the Ambassador "king of Indian roads": The roots of the Amby 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 engine also powered a LOT of cars back then, including sports cars: MGA, MGB, Morris Mini, TVR Grantura, MG Magnette, Morris OXford, Morris Minor and a few Austin and Wolseley cars too.
The plan with this car is to get the engine to run well without a full engine rebuild. So, follow along to stay up to date on this build.

How many kilometres does this engine run?

[@fixpaana]

You mean after the rebuild? Or how many kms it's already run before this? Mileage wise, don't have any accurate data but must be around 50k kms.
