just colored valve covers and intake manifold

[sickbro91]

just have one question. on the side of the throttle body theres that tube that connects to the valve covers. when i was removing that the rubber was so old it just chipped away. is there any way i can run it without that? or is it 100% necessary?

[scott_is]

Its the crankcase ventilation tube...No its not 100% necessary
You will have to plug both end if you want to run without it or
your engine bay is going to be coated with oil and you'll have a
vacuum leak

ahhh. well the old tube was all craked and stuff maybe thats why my avlve covers were covered in gunk alright sweet im going to get some plugs today. in the valve covers tho. should i put a little fliter over it? so it canstill break a bit?

Just get the tube, unless you want to run the risk of high crank case pressures over a $2 tube.

[sickbro91]

what if i did the filter thing?

[CorvallisBMW]

I'd say replace the tube, IIRC it's about $12, less than a filter.

16, and good luck getting the right one. The RealOEM part # is wrong.. I have the later-style hose sitting here because of that.
