I have what i think is a good 6.5 IP but its missing the top metering block. My 6.2 pump is still working but i am getting a little bit of white smoke at idle. I was wondering if i could swap the top metering block on the 6.2 to the 6.5 or should i try to find a metering block for the 6.5.

i dunno bout the ip's but wouldnt white smoke be the cause of a bad injector?
