It has been suggest to me by a Honda technician that a dealer serviceperson could do a "fuel pressure leakdown" test that might explain the rising oil level for the 1.5L Turbo engine. I guess an injector could leak into the cylinder when it should just hold a back pressure until it is told to open? It takes about 1500 miles for my CR-V to show near the top of the orange dipstick, but if it was just a little bit of gas bleeding into the engine crankcase at every shutdown, would a pressure reading pick that up? And where would someone connect to do that reading? Can that be done at all on the high pressure side of the high pressure oil pump? Or can one see the pressure change on the low pressure side of the high pressure pump that works off the cam? Thanks for your suggestions.
