Interesting Greg ;

Have you cleaned out the banjo bolt that begins the ALAD's pressure sensing line ? it's at the back of the intake manifold then there's the overboost protection relay/valve , mine was plugged , I have cleaned it but I still don't get full boost readings at the ALDA so for now I have by passed the relay and easily get 10 # boost when under load and working ~ easy acceleration won't show much over 6 # , you need to step on it hard going up hill or running up through the gears to see full boost .

I really like the red turbo , maybe I'll go find a non California one and rebuilt it for my Coupe , get rid of that ding-dang ARV valve although I seem to have plenty of boost pressure right off idle .

Some oil in the intake is going to occur from oil vapors out the rockerbox vent pipe no matter what .

Keep working on it and letting us know what's what ~ I find this an instructional thread .
