I'll be swapping in an S4 13B in my 1st gen and using my Dellorto so everything is pretty muched going to be stripped off the motor. I want retain the oil injection nozzles on both the S4 lower intake and rotor housings. My question is where do I hook up up the vac nipples on top of the oil injection nozzles? Do they need to be hooked up or can I just cap them? Whats there purpose? Even if I cant run all 4 nozzles, I atleast want two on the rotor housings so I dont have to use the oil inlets on the Dell.

Thanks, Ed

 

The nipples hook up to a four way check valve that receives vaccum from your intake.

 

I longer have that valve. My is complete stripped.


Thanks, Ed

 

I would leave them vented the way they are. They are only used to keep the oil in the lines but from my experience it only takes a couple of seconds for the lines to fill anyways.

 

Thanks man!
