💡 Why is a spark plug port compression checker handy for garage diagnostics?

A steady needle climb signals solid ring sealing while a flat line exposes bad valve seats straight away. - Pull the dipstick tube cover to vent crankcase pressure before screwing the test probe in tight - Crank the starter motor several times so the needle holds its highest bounce point for comparison - Wipe the hex fitting clean after every pull to stop grit from scratching the brass measuring thread - Log each cylinder number side by side so you spot mismatched pressures before buying spare parts ✝️
