A lot of stores now don't list a PCV valve for the 84 Fiero, but list one for the 86. I decided to upgrade mine to the 88 style, to make it simpler and easier to find the parts for in the future. It also cleans up the look of it quite nicely.

84 original layout:



88:



Parts:

2 X PCV valve elbows, HELP! part # 47038
1 ft length of 5/16" brake line
88 duke PCV valve, AC Delco part # 25095452

Simply put one elbow on the PCV port on the TBI, and the other on the valve. Cut one end off the brake line, slide the fittings off, and deburr the end. Stick the barbed end into the elbow with the PCV, and bend the line to fit down to the one on the TBI. Slide the end into the TBI-side elbow, and insert the PCV into the valve cover grommet, and it's done!



I think I'll take it back off and bend it a little more, and paint it black.

Nice job.

Good idea, thanks for posting!

Is this an easier solution than using the parts listed for the '85? Because those seem to be available. In that case, the PCV would go in the same location and use the same hose, right? I did find that the PCV itself for the '85 is a different part number from the '84, probably to fit in the elbow.
