We’ve run a pressure test on our DB2/4 and found that the readings are positive. If the readings had been low, we’d worry there was a leak or a hole somewhere however with high readings, we know that the engine is functioning as needed.
After having sourced this vehicle last year, it’s been sat in storage whilst we’ve worked on two other classics belonging to the same client. Now it’s time for this Californian dream to be restored. With a big re-design coming it’s way, the first step is to dismantle the E-Type. By removing the chrome, trim and lights, our technicians can start working on parts of the car.
The compression test also came back positive, with all the readings as they should. A compression test gives you an indication of the health of your engine, its valves, valve seats, piston rings and whether these parts are wearing evenly.
The tests should show the compressions at 110-115 psi. The test shows how much volume of air and fuel goes into the combustion chamber. If there’s not enough, for example, if only 80 psi were passing through, it would give you an indication of a serious fault in the valves. If the valves aren’t seating correctly, the air and fuel can seep out of the cylinders and lead to more serious faults.
