PUT WATER IN RADIATOR AND IT GOES INTO THE OIL PAN. CRACKED HEAD,CRACKED BLOCK, OR TIMING CHAIN HAS RUBBED HOLE IN BACK OF TIMING COVER. NO STEAMING OR MISFIRE. ANY IDEAS OF THE 3 SOLUTIONS ANYONE?
run some tests. or since basically all 3 will require a tear down, just dig into it and visually inspect. but i'd compression test it and see which cylinders are the problem ones first, to give you a start on where to look.
Run engine without the radiator cap and see if your water level goes down? If it does and not leaking from hose or radiator it could be crack head or hole in back of timing chain cover, Otherwise just needed burping letting out the air in the system ?
