Engine mechanical testing, is a great way to check, the overall condition of your engine.

Consequently, if you are having problems, many of these tests, will show where they are.

So, most people do testing, in a specific order, depending on, what issues they have. But, most of the time, a compression and cylinder leak down test, get you what you need.

So, our first suggestion is always the same before you start any engine mechanical testing.

Above all, Danny’s Engineportal, strongly suggests, that a visual inspection of the engine, is the first step in proper diagnostics.

Is a wire loose ? Did a vacuum line fall off ? So, do not look for a complicated solution, to a simple problem. Because, it is common to have a problem in one area, that impacts three or four others. So, with a little knowledge, you should be able to solve, most problems yourself. And, mechanical problems, are usually the easiest to find.
