2006 Hummer H3 3.5 5cyl - Part 1 - Autopsy to Pavement - Teardown

From Autopsy to Pavement
This is Part 1 of a Multipart Series on a 2006 Hummer H3 with a 5 cyl 3.5L engine and a 5 Speed Manual Transmission. This vehicle refused to start, several years earlier, and just sat where it is, ever since. Total story unknown, the owner reached out to me and asked if I could help figure out why it "wouldn't turn over, even with a jump pack." Upon my arrival, he informed me that they had "gotten it to move a bit after working it back and forth with a breaker bar." (back AND forth is NEVER a good idea, as this can make timing components jump time. Either way, it still couldn't be rotated more than 270° (degrees of rotation) without, what felt like, a very solid stop. After another hour or so, and removing the spark plugs for visual inspection of the valves, no interference could be found. Being that this engine is a TOTAL PAIN IN THE BACKSIDE to do anything on, while in the vehicle, we opted to pull it and tear it apart to find out why.
Follow along to see how this engine went from "Autopsy to Pavement".
All work performed in the owners open faced, dirt floor garage and carport.

I do most, if not all repairs, with tools that I carry around in my overloaded 1997 Crown Victoria Police Interceptor. I perform "On-Site" braking and suspension repairs, amongst other diagnostics and services. My tools consist mostly of Craftsman, a few Stanley, Snap-On, Husky, Pittsburgh, and S&K tools. Scan tools include hand held Actrons, DVOMs, and test lights. I also currently use a Zurich ZR Pro, for advanced and bidirectional diagnostics as well as a Snap-On Verus Pro, for more detailed diagnostics. I'm always expanding my collection, based on need and convenience.

[@HouseCallAutoRepair]

Sorry I'm so far behind on the editing/releasing of the next installments...

[@csflmich2239]

I always learn something from you. I don't have one of these vehicles but still so much to learn, thank you!

[@HouseCallAutoRepair]

The biggest thing this vehicle taught me, is how unavailable parts can become....

[@dkupy100]

LOL Yes, I was wondering why you were using carriage bolts.

[@HouseCallAutoRepair]

The ONLY hardware store in the area that sells the size bolts needed, was out of stock and totally unorganized. (the parts bins were trashed by careless jerks, that put everything back in the wrong place) Carriage bolts were the only bolts they had left in stock (that I could find 4 of) that were long enough.

[@enricomasiello7744]

You have your work cut out for you, not the most ideal conditions for rebuilding an engine. Will be interesting to see what you find once you get in the rear down.

[@HouseCallAutoRepair]

You're not kidding! The editing is tough, too...
