Pressure Testing & Vacuum Testing
Pressure Testing a cylinder head is basic and simple to do but we do much more than that! With our pressure testing equipment, we can make sure we can find any cracks on your cylinder head whether they are internal or external.
We use an oil-based flatbed that can accommodate all cylinder heads ranging from your normal everyday passenger car all the way up to large commercial & marine engines.
Vacuum testing is a complex but simple way of checking your valves are seated correctly and to show if there are any gaps between the seat and the valve. Most gaps occur when a valve has been previously burnt out or that the cylinder head has been “cooked” or got hot, this is commonly found in alloy-based cylinder heads. A simple fix to this is to re-seat the valves until the vacuum pressure is up.
