This works. Trust me. Have done it many times - as recent as 2-3 weeks ago to check for a problem. Once you are set up for it - the plumbing fiting, it takes about a half hour.
There is a small degree of valve overlap.
I use my hobby compressor, dialled back, to hook in to the system. It has more than enough capacity as long as not major leaks, to get to 0.5 bar.
You put a spanner on the fan pulley and rotate slowly while compressing. You will see the pressure gauge rise and fall with the overlap. Turn it to a peak, then put your hand/ear/soapy water, whatever around the topside of engine.
If you have any leaks, you will find them. Trust me.
I had so many it took weeks of assembly/disassembly to get rid of them all. As you loose the big ones, you find the small ones.
The fitting cost about $10 to make up from plastic plumbing bits.
Don't go over 0,5 bar - no need to, and I dont know how much the elbow would take before splitting. But it seems OK at 0.5 bar.
