no logs because I'm scared to do a pull with this going on
adaptation( idle ) bank 1 sensor 1:-1.7%
adaptation(partial) bank 1 sensor 1:14.1%
adaptation( idle ) bank 2 sensor 1:-0.8%
adaptation(partial) bank 2 sensor 1:6.3%
Banks are out.
set up:
single turbo pte5858, ID 725's, walbro 450, 2.8 heads, 2.7 block. stock fuel rail and fpr.
I have:
-pressure tested
-smoke tested
-replaced bank 2 02 sensor
-swapped injectors from bank to bank
thoughts:
Tomorrow I'm going to swap 02's to see if it follows. Also wondering if maybe the stock fuel rails/lines/fpr might be to blame so thinking of swapping back to the stock pump also
I need:
More input or thoughts on what to look for or check. Anything is appreciated. I'm a bit lost as what would be causing this.

Out of pure frustration I was manually moving through every block in the engine tab hoping to find something that would help me.
Nothing really until I hit block 093.
bank 1: 2, bank 2: -9 or vice versa i cant, quite remember.
I don't understand how these got off that much, I used a crank lock pin and cam lock bar so who the hell knows.
I have found a few other threads where people have had similar issues where they just pull the valve covers, pop the cam gears, and vice grip the intake cam into position.
I'm currently working on doing the above. Who knows anymore.
As always i appreciate any input.

Did you crack the sprockets loose? Need to do that. They are held in place by conical tension. No woodruff key. |

yea loose sprockets bar on, set timing, tighten sprokets, hand crank twice. I must have messed something up though. or maybe because my tensioners were without oil pressure for so long due to rebuild that once they primed up they shifted drastically. Either way we will see if this helps, i sort of doubt it. Also hope i did not bend valves  |

He has a large difference from side to side.
They're *both* crazy lean, regardless of the difference... If something is that awry, the trims might react asymmetrically even if there is a problem that affects both banks. Do you have before/after logs you can compare? |

Could be the position of lambdas on exhaust?

my o2s are where the duct tape squares are in this picture. A bit hard to see. I would think those would be ok, not sure of anything anymore though.  |

Did you smoke test the exhaust or just the intake?
Leaking exhaust before 02 needs ruling out

no smoke test exhaust but i did put 10 psi into the tail pipe then moved my hand all around the up pipes to feel for air, soapy watered everything. Nothing. With the wrap on there though maybe i missed it, I might try to smoke test it once i get the timing fixed. last night i moved it from -9 2 to -8 3. sigh
