And what is there is enough pressure to lift the cap? I was at the dealer a couple of months ago to do the brake sensor recall and I asked him (the diesel tech) about my idle. He said it was from cylinder wear due to a "bad" filter (AFE). He then pulled my oil fill cap off and showed me the crank case vapors...it looked enough to lift the cap but I haven't tried..yet.

There is ALWAYS going to be some amount of blowby. That's what PCV and Crankcase Vents are for. The concern is not necessarily how much blowby you are getting (of course there can be too much), but whether or not it is a smooth stream (like blowing through a straw) or coming out in puffs (like making a motorboat sound with your lips). Uneven blowby indicates unusual wear (or worse, piston/ring damage) on a particular cylinder. This would also be evidenced by a compression test, but this is the poor man's way to identify possible engine problems.

That's my kind of diagnoses
 My blowby was even. I always thought the idle of a 7.3 with a good bit of cylinder wear would be like my 96 250k with 650k mi. It idles up and down in a uniform fashion. My truck now has a random hick-up...mainly after its warm. I've read where a lot of other guys on the forums saying they fixed the same issue by finding and fixing bad injectors o-rings. And unless it becomes a must to fix, I'm gonna wait it out until I replace the injectors. Thanks Bill, good to hear you

I talked to Mr Rosewood and he straighted that my injectors tested out completely fine. Bill I was hoping you could tweek with my tunes and see if we could fix my idle issue. The injectors are out what should I look for in the hole? Bill I have a video of the idle if you need it.
Thanks Eric

Can I get help please? ? My truck is the main car for my baby and wife.
Could I get a tune that is tweaked so I can see if this fixes it. Also you can smell fuel when it idles but no smoke. http://i670.photobucket.com/albums/v.../VIDEO0016.mp4 idling http://i670.photobucket.com/albums/v.../VIDEO0012.mp4 driving up a hill

Do you have a Phoenix or an FU2? I can't find a server file with your original invoice number although I do have the original number for the Phoenix.
