dpuma8 Posted December 26, 2014 Share Posted December 26, 2014 Hi everyone! I am making the conversion to megasquirt and swapped over the 280zx turbo distributor. First attempt at priming the oil pump, I filled the whole pump with petroleum jelly and no oil which did not work. Then I filled the pump with oil and tried again by cranking the engine. This time I had oil coming out of the cam oil holes but my electronic speedhut gauges never registered any pressure at all. Does oil consistently coming out of cam oil holes when cranked mean I primed the oil pump correctly and the electronic gauge is just slow to register? Or do I need to show pressure on the gauge before moving onto the next project? Just want to be safe Quote Link to comment Share on other sites More sharing options...
Tony D Posted December 26, 2014 Share Posted December 26, 2014 Mechanical Gauge in a "T" is the only reliable way to know what you have. Crank until you get oil out the lobes, install the spark plugs, start up and run in as directed by engine builder. We filled out engines using a stainless fire extinguisher, blast in five quarts, could see pressure on the gauge since it was going in at 125psi....and started the engine. Check valve prevented reverse flow to the fill vessel. Took it off after initial run-in and tied in Accu-Sump. Quote Link to comment Share on other sites More sharing options...
