Guys, if you read off the Engine No. from the engine bay in your respective cars, you'll more than likely find the series of the engine right there. Usually, the first few characters of the engine no. are included to identify the generation and the particular model of the engine.
Unfortunately, the Motor Registration authorities in Pakistan lack the requisite sense and skip all engine identifiers in the registration book/documents handed over the consumer/registerer, i.e. they only list the numerical number on the engine and not any of the prefixes which identify it in the documents. Lazy b@stards.
