    The car has been down for a year this month. I got engine pulled out last weekend. A few more parts and a lot of time needed to get the rebuild going.

    After getting the engine on a stand a couple weeks ago I finally had a few minutes to pull the pan. What I found was no surprise, the rear balance shaft bearing was looking right at me.

    I’ll continue to disassemble and inspect things at a turtles pace. One thing different about my DSM journey this time around, money isn’t what’s holding me up, it’s freeing up the time to be able to work on it.

    Absolutely! I have the same problem I just finished my 97 Gst build recently, it took a little over 2 years before i drove it regularly. I like the GST make the best, I put a closed LSD in mine, besides the bigger turbo that was my favorite mod.

    I had the house to myself today, so I continued my tear down. One of the head bolts stripped out, but I had this huge extractor that worked perfectly. After I got the head off I flipped the engine over, got coolant in my shoe, and took a photo of the damaged caused by the failed balance shaft bearing. I wanted to get the pistons out today but it didn’t happen. I keep looking for another reason that could have caused oil starvation that caused the balance shaft bearing to spin. Oh well, we will see how bad the rest of the bearings look soon. 008BDBB4-CA4E-40F6-8C18-1DED6EE6B983.jpeg 11F5C2C6-2BCF-4C6A-93F0-DE1EFCBD6BD9.jpeg

    I just realized that I needed to share this to the build thread, here’s the trashed cam journal that I found when I was attempting to install 3g lifters prematurely. I think the same weekend, I was working on the timing belt and that’s when I realized that The oil pump was locking up and I was going to be doing a full rebuild on this. Honestly the longer it takes I have been tempted to just find a running engine somewhere and get it back together. I wanna drive this thing!!!! 4C731C09-B2F2-4069-8C4E-AAB95FD74B4E.jpeg
