Engine Compression Test & Leak Down Detector Kit – Automotive Cylinder Diagnosis
$38.00
Cylinder leak-down tester that pinpoints worn rings, leaking valves, cracked heads and blown head gaskets on most four-stroke engines.
A leak-down test tells you where compression is going. Screw the adapter into the spark plug hole, feed in compressed air and watch the gauge — then listen at the intake, exhaust and dipstick to find the leak.
Key features

- Simple setup — connects to the cylinder and pressurises with compressed air at 45–100 psi.
- Clear gauge readings — shows the percentage of leakage so you can compare cylinders.
