What is this crankcase hose called? TPI
I don't know how it happened but upon all the work I've recently done in replacing the intake manifold and camshaft,timing chain and balancer, one of the crankcase hoses has disappeared into Narnia.
Along the passenger side valve cover there is a metal tube that has a short length of rubber hose going to the throttle body. At the other end, there is a rubber elbow on the tube and a rubber elbow plugged directly into the valve cover. In between those 2 elbows, there is a plastic or metal pipe going between them. That pipe is the one that I can't find and I don't know what it's called to find a replacement.
I stole this picture from someone else's post because it has a pretty clear shot of the part. I circled it in blue and it has an arrow pointing to it.

I thought it was called a PVC System Return Hose/Line when I bought one a few years ago. IDK for sure though.

It supplies fresh air to the crankcase from the T-body. Unless you are looking to be factory original, the later years just use a 1 piece molded rubber hose.
I may have the metal one laying around but will have to check.

Re: What is this crankcase hose called? TPI
I think TPIs are,
85-87 multi piece part (mounts to rear of the valvecover),
88-89 long 1 piece molded rubber (mounts to rear of valvecover)
90-92 shorter 1 piece molded rubber (mounts to front of the valvecover).
Could be off on the years a bit but its close.

Correct for these 2, my 85 and 88 are like these
85-87 multi piece part (mounts to rear of the valvecover),
88-89 long 1 piece molded rubber (mounts to rear of valvecover)

Gentlemen, you are awesome. I appreciate your efforts. Today I scoured the driveway and corners and retraced my steps. I remembered we pulled the valve covers and cleaned and painted them. I went over to the table where I have a piece of cardboard that I used as a cover to paint with. I lifted it up and that stupid crankcase hose was under it. I'm so glad that I don't have to buy this because it's pretty difficult to find one.
FYI, both my TPI cars, my 86 and 87 TPI had this metal pipe running on top of the valve cover to the throttle body. Both have this little hose connecting the valve cover to the pipe.
