How much compression should a 2.5 diesel have ? I've got 205 Psi , is this about right ?

I've measured 350 to 450psi in good running 2.5na diesels. You should test with the engine warm and all the cylinders breathing less the one you are testing (ie, with the glow plugs or all the injectors removed depending on the the type of compression fitting you are using). Also make sure the batt is well charged.
