Is the oil at the top by the intake manifold? do you have a breather on the intake or is it connected to the valve cover? The hose that connects the intake to the Valve cover is there to lub you throtle body and you manifold. that is why there should be oil in that area.

Lube the throttle body? That's a new one. Not true however.
Oil gets in there from the crankcase ventilation system. It's normal. It's not a bad idea on an older car to take the throttle body off and clean it as it can get gorped up after a while. |

Right. If your PCV system isn't funtioning well, or you have excessive blow-by, you will get a build up of crud in the throttle body. Normally, fresh air from the intake should go through that tube to the valve cover. Check or replace the the PCV valve and make sure the hose is in good condition and open.

Then once you've sorted the problem take one can of CRC cleaner carb, take the end of the intake off, rev the engine up and start spraying.
Dont worry if the engine nearly stalls, just stop spraying, give it a few revs and get back into it again. You only need to use maybe a 1/3 of a can or even less depending on how dirty it all looks. If you do have exccesive blow by then the only way to fix it is an engine rebuild. But a simple spray with the CRC every few months will keep everything in the intake nice and clean and shiny.

I'm pretty sure that hot coolant goes into the Throttle Body to prevent it from freezing, if that's what that other guy meant, but I don't see how you could confused that with Oil.

Have you all ever heard of a catch can? Gready makes one and I have one. the can takes the place of the hose that connects the valve breather to the intake. It is good for racing and all but after awhile I got PVC problems and throttle stick problems then when I disconnected the can and reattached it the problems went away. what does the catch can catch you ask? why oil ofcourse, and lots of it. So this shows that oil does go into the manifold:greenchai

I have a related question for you guys. I have been making a CAI for my CRX. It's made out of aluminized exhaust piping. Now which would be better, putting on a K&N breather or the hose that goes from the valve cover to the intake pipe?

Use the hose. Out of all the things I've used(Breather, catch can) I like the hose the best.

Sentanta sense you have the answer to every post on the fourm then you explain the function the hose connecting the valve cover breather to the intake. Because I must have no clue.
By the way I chose lube for a reason. It's funny

Excess pressure can build up in the crankcase. The tube provides pressure relief.
And why would they want to have oil mixed into the Air and Fuel?

Why connect something that relieves pressure form an oil covered area to the intake which inturn connects to the manifold???
