:rolleyes: so glad you were able to point that out. there’s zero point... but I was suggesting if rich is so curious he can blow compressed air in the cylinders since he said was interested versus using a leakdown tester and breaking out unnecessary equipment.. But it’s still a waste of time.

Gee, the only piece of equipment that is needed to get % readings in a leakdown test is a gauge set between the engine adapter and air hose. I'd hardly call that " breaking out the equipment. " This car does not need a gauge set to perform a leak down.

There are two kinds of mechanics. One knows how to change parts ( wrench turner ) and the other that understands why they are changing parts ( engineer ).

I'll also note that the dealership mechanic deals with vastly different problems than the independent. Dealerships work more with failed parts on a very narrow range of newer cars where as an independent works on a wide range of cars and deals more with worn / out of calibration items. The independent must have a good grasp of how a car works in order to decide what needs replaced.
