How to Perform a Leakdown Test On Your Engine (by yourself in a tight engine bay!) 

In todays video I take you through how to do a leak down test on your engine. I will show you how i was able to do this in an extremely tight engine bay by myself. I go through using a TDC indicator and the leakdown testing equipment. This is useful for diagnosing a number of engine issues, especially head gaskets! This one is performed on a 6.0 LS LQ4 engine but will work for any gasoline engine
