Picked up a cool old truck yesterday with an uncool peec motor. Fuel dilution in oil. Has the 7w3906 pump, 9Y1914 pistons (15.2 compression) and 3424 nozzles. Ran dye and 4 of 6 nozzles have fuel in the spanner tool holes.. Going to pull nozzles today, looking for advice. Thinking to go to 3421s and change the turbo.. Any thoughts? Only run 100 miles with dilution. Not worried about the bearings yet. Current arr number 9Y2266

With the 15.2s I would go to 3423s, this is a 425hp nozzle that matches those pistons, short of that there isnt much you can do as the computer will pull fuel when boost reaches its desired level in the programming.

Convert it to full mechanical and be done with the peec crap, just need to tighten up the bleed screws to fix your fuel in oil problem. Like cody said put the 3423's in it. It will fight u in one way or another till you get rid of the peec electronics. Expecially if its a Peec 1 or 2 like it is.
