HELP - Need oil flow diagram
 

I am in ned of an oil flow diagram or at least a verbal explanation of the oil system for a 73 2.4 engine. Please post a link or if you have a PDF mail to; ahdoman@socal.rr.com

Thanks

This information is easily found using the search feature. You do not say whether your engine has an external oil cooler, so here are both diagrams.

This shows the flow without the oil by pass mod done?

Can you draw in what the mod does?

Actually Craig, the upper diagram clearly illustrates the OBM. Excess pressure from the pump (gray lines) is routed past the pressure valve into the inlet to the pressure side of the pump (green lines). The lower diagram is of course the original 901 and you can see both pressure and overpressure valves dumping to the sump (little pink branches)
