if leaks are that bad
always check the engine oil level before you drive off
fixing oil leaks on motors
degrease whole motor top and bottom
start with replacing the oil sender it may be the cause of the oil light coming on
after degrease
lay cardboard or paper under the car
take out for a drive and park over the paper over night

leaks from a V6 motor
rocker covers/ spark plug tube 0 rings.engine seals
cam seals
front and rear engine seals leak often
sump gasket can leak
if oil consumption or light on continues
can be a failing engine oil pump
or worn main bearings giving low oil pressure to the whole engine
you could be burning oil from worn piston rings
or hardened valve stems
a mechanic can fit an oil pressure gauge to the motor when hot
to check running oil pressure to confirm low oil pressure
if engine is worn out
it is possible to fit a lower mileage used motor to your highlander
its often cheaper than and engine rebuild
