Frequently asked questions
What does a leak-down test tell you?
It shows how much and where a cylinder is leaking, which separates ring wear from valve or head gasket problems and guides the repair.
Is testing worth it on a used engine purchase?
Yes. A compression and leak-down test before you buy or rebuild protects you from investing in an engine that is worn out.
