Same pressure gauge for compressoon test AND manifold vacuum test?
Hello all together
a few months ago I started servicing my E34 535i. The next thing on the list is measuring compressoon on each cylinder and also measuring the manifold pressure. Can I use the same tool for both procedures? I have noticed that there are special gauges with marked/coloured scale back plates. Do you have a good recomendation on what pressure gauge to buy?
Thank you
