80 300SD hard start with warm engine
I have been having intermittent hard starting with the engine warmed up. The problem only happens after the engine has warmed up to 80-90 C. The car has new glow plugs decent compression (300+ average)and starts right away when it's cold (below freezing).
The car always starts eventually but I have to crank for awhile 10-30 seconds. Same problem when running on diesel or veg and with oil just changed or ready to be changed. I don't think that I'm getting air in the lines and again it's intermittent so sometimes it starts right up when warm?
