So we took the bay to Cornwall, 307 miles,engine had just been serviced and set up. 25 miles from our destination- perranporth, it lost power and cut out,white smoke coming out of air filter and when I dipped the oil was empty. Will turn over on key but not by hand. Oil light didnt seem to come on and I have a temp dipstick which wasnt flashing.(as far as I know). Will the engine be a total right off? I do have a 2.2 legacy engine with kep adaptor sat in the wksp. It's being recovered back in the week.
