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. |

Check of cylinder deck shows that we have some flatness issues that need to be corrected.
I was able to easily get a .004" feeler under my straight edge. Straight edge is .0005" out of flat as judged against my granite surface plate. ![]() My flat edge spans both cylinder spigots which is the best way to judge this surface since both cylinders need to be on the same plane for the heads to seal. They could be corrected later via cylinder base shims. However, in theory they should be on the same plane to minimize downstream problems later with sealing, valve geometry, and compression ratios. I will fly cut this deck surface once I finish pulling the various studs from the case halves and get around to Tramming my mill to ensure that they are surfaced flat. |
