[QUOTE="Big Bore, post: 40330, member: 760"] No it would idle for a bit, then ICP would spike and it would die. He had a pin diagram for the main engine harness connector, and did a continuity test from the main connector pins to the VC connector slots for each cylinder. #2 pin had continuity on #4 slot in VC connector, and vice versa for #4 pin. UPDATE! Went back again yesterday and we found bent p rods in #4, one pretty severe ( I believe it was the intake), I have pics on my phone I may try to post up later. Replaced those, fired it up and took for a spin, started making all kinds of racket and smoking bad again. Pulled VC and found broken rocker on #4 intake. Replaced and also replaced the p rod that bent at the same time. Cranked it this time to see if rocker was operating and if it would have any issues. It wasn't. Fired it up and rocker was working fine. Almost no smoke at idle except a very slight haze of blue, but under throttle it blew quite a bit of white smoke. It also still had a miss and contribution test failed #4. At that point I had to leave as it was getting late. Buddy kept messing with it, pulled injector and nozzle was crusted also bottom o-ring was toast. Additionally it has started using a lot of oil. Like a spin around the block will use two quarts. The intake, compressor, hot side IC pipe are full of it, and oil is dribbling from the tailpipe. Turbo is TIGHT and fairly new so it's not suspect, especially since it's obviously in the intake right after the PCV. Pretty sure it's getting blown by out of the crankcase. Buddy cleaned the injector nozzle and installed new o-rings and thats as far as he got. Waiting to see what happens today. He has injectors in the other motor but they are AD code and the injectors in the installed motor are AB code, so he's leery about using them. I think he would be ok to use them just to test the hole. I think he's going to do a compression test on that hole also. He has said earlier he didnt to want because he didnt want to know lol. So thats where it's at. He's had the VC off that bank at least a dozen times now so I think he's about done. Wish I had more time to help him with it. [/QUOTE]
