Last week I bought engine GA000099 from Freezing914 in the hopes of picking up some spare parts to support rebuild of the engine that came with my vehicle.
During the teardown of my vehicles engine, it is quickly becoming clear that the engine was abused by some DAPO. Cooling flaps and thermostat had been removed. Rust in the sump. The crank was scored and already 0.010" undersized. The oil pump was torn up. This is just the tip of the iceberg on the engine that came with my vehicle. (IMG:style_emoticons/default/chair.gif) 14 hours of driving seems to have netted me an engine that might be worthy of a rebuild. (IMG:style_emoticons/default/piratenanner.gif) This engine appears to be bone stock. D-jet mostly complete. As an added bonus I discovered upon teardown that none of the cooling tin fasteners have ever been disturbed. No screwdriver marks! But . . . like any engine of this age and unknown origin, it absolutely needs to be gone though. |

Other than the exciting arrival of heads, my 914 work this week was pretty . . . weak.
I did drop of the engine tin for degreasing. That will go to powder coat once done. I also dropped off GA000099 cylinders for degreasing now that I've determined that they are in great shape and reusable. Did get a bit of disappointing news from my machine shop. Let's just say their customer record keeping is not what it should be. Apparently they can't find a source for the rod bushings and want me to order them. Not a big deal. However, they had the rods for the past 2 weeks or more. When I finally called to check on them . . . . you guessed it. . . . they lost my phone number and were waiting for me to call them.
