Some of the most important checks carried out in the GTE workshop aren't necessarily the ones you can see.
Vacuum and pressure testing is an important diagnostic check used to make sure an engine's crankcase, gaskets and seals are airtight. That's why we include it as part of every applicable service carried out in our workshop.

A small amount of air is introduced into the sealed system to check whether it can maintain pressure. If it can't, this can indicate a leak from areas such as gaskets, crankcase joints or rubber components.

We then check whether the system can hold a vacuum. This is particularly important for identifying problems with crankshaft oil seals that may allow unwanted air into the engine while it's running.
On 2-stroke machinery such as chainsaws, strimmers and leaf blowers, an air leak can cause poor acceleration, erratic idling or a dangerously lean fuel mixture. If left undetected, it could ultimately result in engine damage.
Testing also helps our technicians track down hidden leaks that might otherwise be difficult to identify.
