Performing an e36 compression test is a simple way to find out how strong the engine is.

My 1994 BMW 325is (or e36 generation) has over 200,000 miles on it and is going strong. However, in order to find out just how strong the engine is, I will be performing an e36 compression test. The compression test results will show us if there is any significant wear or tear in each cylinder. For example, if a single cylinder is down on compression, we know there is probably an issue with the piston rings or cylinder itself. Consequently, the engine will make less power and may even start showing more severe symptoms.
