It seems like shortly after converting to 100% bio, my truck started smoking BLUE smoke at idle either in neutral or in gear. It does not clear up if I race the engine in neutral. It does APPEAR to clear up when I run it down the road (unless I just can't see it through the rear view mirror) The first time it did it, I filled the fuel filter with Diesel Kleen and it cleared right up for a few days. Now it's back. Any suggestions? I have original IP and injectors 167K miles. Thanks Tom
Pretty nice mods list. Did you turn up the IP any? Might just be time to have the injectors rebuilt.
Any other symptoms... hard starting, oil consumption, etc?
I believe you are right about the injectors. It idles pretty good and runs at cruising speed very well. I turned up the IP when I installed the Banks. I am installing "G" injectors this week. Thanks Tom
