I tried searching this some but found it very difficult. What is the one(or more) things you would to do your engine before modding anything? I've seen in places doing a compression and leak down test to check the health of the engine, is there anything else? I plan to mod at some point (not huge power in my future, just a real fun DD) but want to make sure the care is good and healthy first.
