Mystery nipples
 

ive got a 88 t2 with the upper intake mani. (pd failure).what does that little nipple in between the oil injectors go to? also what is that little metal deal that has 2 vacuum lines coming out of it is on the inside of the lower intake manifiold?what is it and where do the lines go?

The one b/t the oil injectors is for the fuel injector bleeds. It supplies fresh filtered air from the back of the throttle body. DO NOT CONNECT A SOURCE OF VACCUM to this nipple. The suction comes FROM the nipple.

I'm lost on the LITTLE METAL DEAL. It might be part of the cold start system. Just a guess. I need a picture or try to describe it in a different manner. You did good on the first description, but its not making a connection in my head. Is one of the 2lines larger than the other/????

2 bolts
 

its held on by 2 nuts it is on the lower intake mani. and its above the oil injectors

Its a piece thats not needed. Was part of a cold start system(cold start as zero degrees). I believe it injected fluid in the intake when the temp was reaaaaaaaal cold. Take the thing off and block the holes with JBWELD or make a simple blockoff plate with some rtv under it. SEe page 4B-90 of the 87fsm for a description of how and what it was/is. Called SUBZERO STARTING SYSTEM. Outlawed in the Western world. Its the only item I condone being taken off a engine. Should be able to cope with the rest of the items being left in place. But then again, its our cars and we'll do darn well what we want with our property.

Damn, and i thought this was going to be something kinky.....

yeah me too... my nipples are kinda small so i was thinking that my nipples could be mystery nipples... get it? damn...
