Engine GA000099, An early GA engine rebuild thread Options

[Superhawk996]

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.

I started cleaning up the stock pistons from this 099 engine. Overall pistons seem to be in great shape. I need to measure them to make sure but likely will reuse them with new rings for this build.

I used the ultrasonic cleaner with some simple green but it still struggled to get some of the really tough carbon off. Wondering what cleaning solutions folks are using with better results.

Purple Power seemed to be in wide use based on quick troll of YouTube. (8/8/2019 post edit: Purple Power not recommended for Aluminum via their Website FAQ)

Could resort to carb cleaner but the smell of that stuff will permeate the garage in a hurry. Then the wife starts to complain as it makes it's way into the house.

To me, it smells like Hoppes #9 (pure heaven), but, my wife hates the smell. Women. (IMG:style_emoticons/default/rolleyes.gif)
