Hi all,

I have a 1987 740 with the b230f.


The fitting labeled as '6' has cracked at the very bottom and the crack is about 5mm long going up. I know that fitting is dirt cheap, something like $5, but due to the coronavirus i cannot get one from the US due to Australian air travel restrictions and there are none in Australia. My question is, is it OK if its cracked a little bit? There is no oil coming from it, but i was just concerned that it might cause a vacuum leak. Or the oil trap system doesn't have to be vacuum sealed so its OK if there is some leakage from the atmosphere?

Thanks.

 

yeah, crankcase isn't part of the intake manifold vacuum thats critical.

 

I wouldn't worry about it, you can wrap some tape around it or some other sealant. That PCV system is part of the emission control...
