Hello all, I am new to the forum and I hope to give as much as much as I get here. I've been a chevy fanatic all my life. On to the main event. The other day had the first major problem that was unexpected. The vacuum pump seized and grenaded it's entire drive, pieces all around the exhaust cam and reluctor and cam position sensor(cmp). Noticeable scratch marks on the reluctor. Also DTC's P0014 - P0017 - P0556 The first is for Exhaust cam too far advanced, the second is Crank sensor/Cam sensor correlation (out of sync) and the third is for Brake booster pressure sensor circuit/ performance. I removed the vacuum pump and noticed oil sludge build up around supply hole. So after picking out as many pieces of aluminum I could get with tweezers and the metal lugs with a magnet I did flush the engine and changed the oil before installing new pump. Then I cleared the codes and started the engine. It took some time but all cleared. So I thought, P0014 and P0017 came back which also put the car in limp in mode (Reduced engine power) I have checked everything, cleaned the actuator solenoid twice also pulled valve cover to check the timing, check the cam reluctor make sure it was in time, and found the one missing piece of vacuum base that was under the exhaust cam lobes of number 4 cyl. I've tried swapping the actuator solenoids and the cam position sensors (because they are identical intake and exhaust) and still get mainly the P0014 code with the P0017 as a pending code. One other problem that came up is after the car goes in closed loop and operating temp the motor dies. The last checked fuel pressure was on the freeze frame data that read 1420 psi/w 59 psi initial........ so if anyone has had anything similar happen, can you help me with this? I'm missing something?
