Alright so here's the back story. I have an 03 trailblazer. A couple weeks ago, my motor had a bad knocking noise. It did not sound like it was coming from the bottom end. I was thinking that it was possibly the timing chain. After a few hundred miles, I developed a bad miss at idle. I also came up with code P0014(exhaust camshaft timing-over advanced). This was the only code that came up. I had no other vehicle to drive so I had to stay on it. With the code that came up and the miss only at idle, I was suspecting the vvt actuator solenoid(I had had a code for this before but it went away.) So I replaced it as well as a fresh oil change. This did nothing for the noise, but I figured it needed to be done anyways. I mad it about 100 miles before it started dropping oil pressure on takeoff. Still full of oil and no external leaks. I made it almost home when she popped and died. Had a friend tow it home and started tearing down. After getting the valve cover off, I discover my rocker arms were very loose. I thought maybe that was my problem, so I went and got some new lifters. I was trying to turn it over to tdc when I realized that number 1 piston was not moving. Some slight pressure on my extension and she dropped to the bottom. I knew then that I was screwed, so I started a search for a donor motor. I found one for $350 so I jumped on it. They said it was running great when parked just had electrical problems. Drove the 2.5 hours to get it and the damn thing was locked up. Kept searching and found another. They wanted $500 for it but it came with a 90 day warranty. So I drove the 3 hours to ohklahoma and picked it up. They said that it was tranny problems. Motor rolls over fine, no water in oil(clean) and wasn't too dirty. We picked er up an put in the truck.
So here is where I'm at. I'm getting the old motor out. I've got almost all of it unhooked(except starter) and am trying to decide whether to put the trans with the motor, then split, or to leave the trans. I already have my whole front clip off. What do you guys think? I'm going for easiest and quickest. If I have to choose, then easiest.
Right now I am pulling everything off the donor, to put my stuff back on(intake, throttle body, accessories, sensors, etc. This is for nothing more than assurance that she will start up(I know everything on mine was good,plus I just bought that new vvt actuator).
One question I do have. On the donor motor, there is a small canister type thing on the pass. Side. It is bolted onto the top where the trans dipstick bracket it bolted. It has a heater hose attached to it(not sure where it went, they already had it cut when I got there) an also an electrical plug. On my motor, it has a plate bolted there and no loose connectors just laying out. Anyone know what this is? I have an 03 an the donor came from an 04. Do I need this? I'm assuming that it is some sort of option since it appears that my motor has a hole for it, but is blocked off. I believe the only difference between the two vehicles is that mine is 2wd and the other is 4wd.
Thanks again
