The gauge will hold peak pressure if it is the type designed to do so. If such, it will have a release button to zero the gauge. It not it will register the pressure it sees. You have to watch it and read peak pressures. In the case as described (dropping pressure) that would indicate either leaking valves or worn rings. Do a dry/wet pair of tests on each cylinder. (test dry then squirt some oil into the cylinder and test again.) If a noticeable improvement you have worn rings, if not, leaking valves.Date: Fri,

Hi all.

I bought a compression tester and tried it on my parts van 1.9 WBX engine. On two of the cylinders, the gauge would drop while still threaded in sparkplug hole.

I was doing this w/o remote starter.

The gauge should hold its' reading right? i.e. once it's pumped up, it should stay there correct?

It was threaded properly, and adaptor to hose was threaded properly too.

Apologies for such and elementary question!

Neil.
