An oil accumulator makes that pretty easy. We run one on our truck and before every fire up we pump oil through the engine with it. And you don’t need an oil heater, just run the engine for a bit. We run our junk on jackstands to heat the engine oil, trans fluid, and diff before a race and it only takes 10 minutes or so to get some heat on the oils.
Ok, thanks. I don't know much about the Nascar motors. wasn't sure if they need something special, seems everything I have watched, they all do the same thing, spin the dry sump and run through an oil heater.
