ceejay.lets look at your problem up close.your burning lots of oil.you blew out the oil pan gasket.you dont know where the oil is going it only has a 100,000 k.heres what i think..... you defiately have too much crank case pressure which is pushing out oil and gaskets. #1-.... have you checked your antifreeze for oil,if your head gasket is shot it could be getting into your antifreeze and also pressuring you crank case.#2-have you checked your pcv valve to see if it is working correctly and if there is any cracks in the hose.pcv-positive crankcase ventilation,exactly what it does.so that you dont get positive pressure when the pistons are pushing down which would push out oil. # 3-have you done a compression check,this could indicate a collapsed piston ,is there any engine noise? if compression is low. squirt a little oil into the cylinder via the spark plug hole and if the comp raises you can assume that the rings are gone. ok if comp is ,lets say 120 or up all across the board and there is no varience of 10 per cent or more.i would change my pcv valve,change my air filter and breather filter,clean out the air cleaner cover,change oil and filter.make sure antifreeze has no oil in it.when you change the oil make sure to do a 20 minute engine flush,with what ever product from your local napa first. this is important because you probably have a sludge build up and this might clear out passages that are important forproper crankcse ventilation like the inside of your valve covers. note - this is the cheapest fix,first.and if it works you should get another 100,000 on that motor.letus know.... ps: look at the back of your motor to see how much ,if any oil is being lost out your valve cover gaskets.i had a motor once with only 20,000 on her and she was going through alot of oil.it was because when moving there is a lot of oil in those covers and its running out the back .when stopped the oil runs back into the crank case and stops leaking. becuase the valve covers empti of oil,so when you do that recomended tune-up i perscibed,change the valve cover gaskets and i bet problem solved...
