Variation of oil catch can (1990)
 

I finished the 90. I mean finished . Down to wiping the engine down and air intake , all the little parts... DONE! Pardon me but it turned out GREAT and beautiful as only an LT5 can. Now the bad news. Oil drips after dry for 3 weeks from the valley . Good Lord. Pulled everything back apart. IH was dry, valley was wet, pvc pipes to pcv box was dry. PVC box toque was still proper, new gaskets. That?s the only thing? Car hasn?t been driven , only about 30-45 minutes idle time. (Actually a few drips out of stock headers converts too-few drips) could. It find definitive cause. Replace pvc box with new gasket. I am using Jerrys new pcv hoses and dual adapter (this is In me that I noticed later, I zip ties the duel pcv valves to the line like the Oe was, I may have pulled the tie too tight block flow through that line , just a guess , doing it different this time. Which brings me to oil catch can. I am taking a parts air bleed tube and cutting it at the rear of plenum and cutting the other side to go into the pcv dual hose and route the new pcv wires to my small micro can to right of brake booster. Any obvious problems with this plan??? Waiting on new plenum gaskets and oil catch can to arrive tomorrow.

You do not need to cut the line. I used a 3/8" male NPT adapter from home depot (two of them) one in by the throttle body and the other at the pcv/map outlet. I used this with stainless steel braided line.

Thanks, my thinking was to make a small as possible deviation from stock appearance.
