Leak down

Dont worry about compression as much since you are doing a leakdown. If your engine is below 10% then I would say you are good to go. If it is below 5% then your engine is almost brand new.

The best time to do a leakdown is when the engine is cold. Start the car and let it run for 30 seconds. Shut it down and then go to town. This will be the most accurate numbers... from what I have heard.

With that low of miles if it has been well cared for you should be around 5-7% or less.

Best of luck with the PPI and the new car.
