order a new hose from gm... i forget the part number but im sure shoebox or someone else will have it soon for you. i had to replace mine a month or 2 ago so i know gm still has them floating around in their parts room

i work at a dealership so its quite simple for me to check on whats discontinued and what's not

shoebox

GM PART # 10128361 for the U shaped hose on 93-94s.

The GM number is still good. The part should be available.

i did a full tune up including optispark, plugs, wires and pcv valve and hoses and egr system.. so i went ahead and bought all the hoses that i could find to go with all the new parts.. i have to worry about emissions where i live so im hoping all these new parts will get me by until my car hits its good ol 25 years old then i wont have to worry about that bs anymore

Hey guys thank u it turns out it was my pcv valve was clogged it had oil in it buy my oil isnt leaking anymore.but ill need to change the pcv valve i just cleaned it for now.and the pcv elbow hose is good.

It rattled and it had vacuum, but it was clogged? And if you were able to clean it, why do you need to replace it?
