Please help: Oil in throttle body and burning anti-freeze
i have a b18c in my 95 civic and it has been burning alot of anit-freeze so i assumed it was my head gasket. i bought a new toda multi layer headgasket and when i went to put it in, it seems as if the head gasket it fine. i see no visable problems with it.
It looks to me like there is oil in throttle body and intake manifold. The combustion chamber is also very dirty. I also have three CEL codes which are Idle Air Control, 02 sensor, and one other one that had to do with the idle.
The anit-freeze in the bolck seems to be very clean and the oil when i draned it seems to be clean also. and the engine has also always burned abit of oil (about a quart in 2000 miles).
i will be posting pics in a few hours or in the morning. Please help and give me some idea as to what is wrong. thanks alot in advance.

The bottom of your head might not be 100% straight . It happend to a friend of mine the samething and he needed to get his head shaved a bit after that he was good to go !
Im not saying thats whats wrong with your just a personal experience .

i thought that may be a possibility but if that were true then anitfreeze would be in with the oil and vise versa. so to me it doesnt seem that it would have anything to do with the head gasket. although it may still be a possibility. im going to put it all back together and see what happens. but if anyone has any more suggestions, they would be useful. thanx
It's posible to warp a head and not leak coolant into the engine oil. I've seen it before. Has the car ever been overheated? If not, I'm betting you have a cracked head... Check for hair-line cracks around where the studs go through and around the coolant passages. They will be small so look hard. As long as you have the head off, take it to a machine shop that rebuilds engines and have them look it over. They may be able to give you some help.
it could be that your PCV valve is bad. It could not be stopping oil from getting into your intake manifold.
Also, your intake manifold gasket could be allowing coolant into the intake and then into the head. There's a channel through your intake manifold that goes into the head where coolant flows. It's a square hole on the back/distrib. side of the head.
Just a couple more ideas.
hih

ok ill check over the head real good to see if the head has any cracks. and the engine has been overheated once before. when i first got the engine i had my dx radiator and it was in bad shape anbd it over heated once. other then that it never has to my knowledge.
also, i took the intake manifold apart last night and and on the lower half of the manifold on the back there is a think attached to it with two hoses, it kinda looks like that is where the oil is coming in because its the dirtiest and the side on which that is one is the side of the engine that is hte dirtiest. im gonna take some pics soon, so ill post the up.
and can someone give me the tourqe specs on the headbolts and the bolts that go through the cam plates(i think thats what they are called).
