  • OK. Back on the road to progress. Casey and the supplier worked something out and we're getting a relatively low mileage Corvette engine ("It's got a Corvette motor in it!") and I'm hauling back the two bad replacement engines. ME and I are heading up to Greensboro tomorrow and we'll get 'er done.

    Just a couple of shots of how I spent Christmas. One of the pallets was useless so I modified things a bit and now both sit upright like they meant to all along.

    Notice the horrors of snow here in coastal NC. I shot these at twilight so everything is a tad orange.

      • The SS engine (LS2) and some of the 'Vette engines (6.0) are the same other than the intake (or so I've read). Basically, I'll strip the Corvette engine down to the long block, change the pan & pickup (the SS is front sump) and install all of the SS stuff, making a 390 HP instead of the 400 HP that the 'Vette makes. The difference is supposed to lie in the intake.

        Anyhow, it's home and sitting in the shop. Pics and more info tomorrow (we got home late and by the time I got it unloaded it was "a day".

        • I hate that it's been such a PIA for you Dan.
          It's painful reading, mostly because it's the kind of crap that happens to me EVERY time I try to save a buck. And even sometimes when I don't. :-(

          You're a good man Charlie Brown!

              Doing it all wrong since 1966

              • We had a TON of it - in 1986 (or was that 1989?). We rarely get more than a dusting and even that is uncommon, just like I like it. Just enough cold weather (which we're having as I type) to keep the bugs down to smaller sizes.

                • Switching the engine over to a Trailblazer SS-compatible configuration:

                  As received (other than putting it on a stand):

                  Note that some stuff, like the alternator, is missing. I had to get the wiring harness off the rear of the engine and to do that I had to pull some stuff to even get it on the stand.

                  Side-by-side of the two engines. For those keeping score, the one on the right is the Corvette and the left is the original engine that GM put in the SS. You can see that a LOT of stuff is different.

                  A complete '05 Corvette engine wiring harness. It seems like this must have SOME value. I was careful not to cut or butcher anything on the harness so it would be great for someone with "issues".

                  After a can of brake clean, here's the 'Vette engine. It wasn't bad to start with but it cleaned up pretty well.

                  And the original engine, mostly stripped. Note that I have to exchange water pumps and I'll also need to swap the front crank pully assembly. Lots of stuff is exactly the same but different.

                  I had to reassemble my old orange engine stand and now I remember why I popped for the one with the gear-driven turner. Future stands will all have that feature though I rarely have 3 engines on stands at the same time (I also have my spare Mercedes Diesel on a stand). The LS is light enough that it isn't TOO bad to rotate.

                  Tomorrow it'll be onto the pan/pickup swap.

                  • Forward!

                    I got the water pump gaskets (the old ones might have been reusable but I'm taking no chances) and the WP is now on the 'Vette engine. I also swapped lots of little stuff and got both pans off. I have a TON of cleaning to do before I install the correct pan on the engine going in the SS.

                    Trailblazer oil pickup:

                    And the Corvette pickup. As you can see, they are not at all alike. Not sure on the windage tray yet but it looks OK - the less crapped-up stuff I transfer to the 'Vette engine the better.

                    Inside the pan from the original engine. LOTS of schrapnel. If I was a gazillionaire I'd toss this pan and order up a new one but given reality I'll scrub the snot out of this one. I pulled the plumbing to the oil filter base (in the middle of the oil pan on this engine) as well as the pickup and I'm scrubbing those in the parts sink which I'll follow with a soap & water scrub and then clear water.

                    As a comparison to the pic inside the original pan, here's the 'Vette pan. A little grubby but no shiny bits. Note that this pan doesn't have the extra splash shield (windage tray?) and so would be a ton easier to clean but the pan-mounted tray is riveted in and so will have to stay there as I do my scrubbing.

                    Last but not least, an overhead view of the general mayhem in my poor shop. Once all of this is either installed in a car or shipped out as the core engine maybe I can find the floor again.

                    • Is this just crud or a hole in the dipstick tube on the Vette engine?

                      • It's crud (sharp eyes!). I don't think the 'Vette dipstick and tube is the right length anyhow so I'll swap it for the SS assembly.

                        I got the pan, oil filter tubing (I'll show y'all in a pic tomorrow), and oil pickup all cleaned and they're drying overnight so I can put all of that together tomorrow. Everything looks really clean so I'm feeling pretty good about that.

                        Also got the dampner back on (they are different between the two engines),. I rented the dampner installer from Advance but it will NOT work on an LS. The LS dampner bolt hole threads start way back in the crank (like, maybe 2" or so) and none of the adaptors in the kit come close to working with that. I experimented on the dead engine and found that with light taps I could drive the dampner back far enough to pull it on with the bolt which is just what I did. I hate to tap on the thrust bearing but it really went on pretty easily. If I was going to do more LSes I'd get a couple of dampner bolts from Pick-N-Pull and weld them end to end so I got a really long bolt to pull them on but this is likely my first and last.

                        Did some other little stuff too as I work toward getting this rascal back on the road.

                        • I know you have done this type of stuff before and more things than many would attempt Volvos with Ford engines,Diesel S10 and more.
                          I just wanted to show you this rough drawing of a tool that I used to use to install dipstick tubes with.
                          It is a piece of black pipe with the side ground out for clearance so it will go half way around the tube, and the bottom ground to the same angle as the lip on the tube.
                          Then you can carefully tap the black pipe in while holding it at the correct angle.
                          If it is angled to high the point on the bottom will dig in to the tube lip.
                          Ask me how I know....

                          • Thanks for the tip and I'm sure your tool would work great. Luckily, the LS dipstick tubes are pretty easy to slide out and back in just using your hand - I did that on Engine #2. They rely on a bolt to the head to hold them in place. But I have had them so tight they're almost impossible so I feel your pain and I'll keep your design in mind for the next time I run across one of those.

                              Oil filter tubing, internal to the pan. Note the gaskets and how the tubing runs - simple once you see it. I felt I had to pull that off to clean out the schrapnel.

                              Proof that Murphy's Law is still on the books. My finger is pointing at the location for the Corvette dipstick while you can see the SS dipstick installed in the pan. The 'Vette dipstick tube hole is 3/8" (so much for GM metric) which is the tap drill size for 7/16" course. I greased the snot out of my 7/16 tap to catch the chips and tapped the hole part way down. Then I made a plug out of a 7/16 bolt.

                              And Bob's yer uncle, a plugged dipstick hole. I RTV'd the threads mightily so it ought to seal well.
