4age water and oil problem

[oldcorollas]

what about he coolant lines to the throttle body?

think about it step by step..

apart from turbo, the crank case has a few connection.
first is PCV valve from cam cover to intake after TB
second is from rocker cover or crank case to before the TB (ATM side on NA... on turbo you wanna check that line will not be pressurised.. ie put it before turbo)

coolant to TB may also have a chance at getting into enging, since there are a few lines there (vac as well) that coulod be mixed up... but they are not oil lines.

also, wrong head gasket... one of the coolant passages not matching up between head and crankcase....

by PCV you mean the tube that sticks out the top of the rocker cover? cause it aint hooked up to anything?

can you give us some more info on this

also the head gasket seems to line up with the galleries allowing only a small area for stuff to travel through, the bottom side of the head gasket which was that black colour has seemed to react with the block metal or something, kind of looks like the begining of corrosion, will post a photo soon.

there are two tubes from cam-cover/crankcase to the intake.

one pipe goes to before the TB or before turbo. this is to allow excess air pressure in the block, from blowby, to escape the block. it goes to in front of the TB or turbo so the dirty air gets sucked into engine (less smellies)

the other one goes from after the TB, between TB and engine.
the PCV valve is a one way valve.
when there is vacuum in the manifold, it sucks air thru the one way valve, from the cam cover/crankcase. this air is both from blowby, but mainly from the other tube!. the idea is, that during cruise, some air gets sucked thru the engine, and this helps to remove contaminants from the oil, such as fuel and water vapour, that boil and sit inside the crankcase air.

in turbo, you don7t want the one way valve failing, cos then presurised air gets blown into the crankcase.

i think most likely will be some problem with the headgasket, as that (apart from turbo) is abotu the only place for oil and water to easily mix....
any little leak of water from headgasket into sump will do the milkies

edit, if it is not hooked up to anything, then it should not be blocked... the block needs a way for air to get out... if you block the PCV gear and don7t allow venting.. oil can piss out of the seals
