but why would oil spit out of the hoses? This engine is for a Formula SAE car so we are planning on designing our own intake system. what would that mean for those hoses if they were going to the airbox?

 

I can't say why oil comes out. But since you are doing a custom job, ensure you have the engine mounted at the right angle.

The vacuum hoses (i'm not sure 100% here) running to the airbox are usually part of the PCV (positive crankcase ventilation) system of an engine and also manage the warm/cold air mix. That's from many years ago on old car carb'd engines. The drawdown on the intake header/airbox is used to generate the vacuum running other functions on the engine.

 

yeah i knocked those off when i was installing a manual ape cct on my bike. they go to the air box. but i do not recall oil spitting out mine, i think something is weird here.

 

Should I just run it with a catch under the hose and hope that the oil stops coming out? Or could I just cap it? Do I even need the vacuum hoses to run the engine?

 

Is there that much oil coming out, really sounds wierd. Sometimes a little oil vapour condensation in the hoses might occur but what you say seems like you have an oil line in you hands. How much oil do you have in the engine? Does it start / run ok?

Wierd.

 

yep it starts but like after 5-10 seconds oil "spits" out its not a constant stream. you think that
it maybe something thats a fluke and if i were to run it longer it would stop? I mean you saw the pics i posted those are the lines. we put somthing like 3.5 quarts in there. Is that to much? I watched the oil window on the side of the engine and stopped in the appropriate spot.

 

3.5 is about perfect so thats not your problem.

 

throttle body tubing? http://www.bikebandit.com/assets/sch...a/HJ510045.gif

edit: hell i dont know

 

actually we found out it was a plug that wasn't in place lower on the the engine, same vicinity so thats why we thought it was the hoses. That problem is solved but a new one has come up... what goes in the hole that I have high lighted in the picture. Oil pours out of this hole, im talking like a steady solid stream. we were thinking an oil pressure gauge but there is noting about a gauge being there in the manual.

 

Anyone... anyone? Bueller??
