Just picked up a 99 Escalade, 5.7 Vortec - 145K miles- it was displaying a P1345 (cam timing) & P0161 (rh/rr O2) code.
Corrected timing, cleared codes and she ran much better.
Full tune up... The old #'s 4 & 6 plugs looked dark & sooty... the rest were perfect.
Noticed a bit of smoke when it first fires up... but not blue.
O.K. - at first I'm thinking spider or injectors (pintles).
But, it looks more like condensation. Oil is dirty, but is not milky (as is oil cap).
PCV & vent cap have a bit milky residue though.
Runs well, but a tiny bit of a rough idle. Decent power - now.
Drove 30 miles, and set a different rear O2 & RH cat converter code.
All codes are on the RH side, a bit of moisture inside the engine ventilation system, #4 & #6 plugs dirty
I believe I have heard of intake gaskets doing this before... can anyone verify?
Pulling intake this evening - would love some verification
