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.

Still working on GA000099 slowly but surely.

I've been cleaning up pistons to figure out if they are worth reusing. I'd really like to reuse but the thought of building up a 2056 carburated engine has crossed my mind. I haven't ordered the cam for this engine yet so still some time to decide.

In the end, I know I want a dead stock 2.0L FI engine for my project and have purchased 94mm NOS P&C's and a NOS cam to build that. But I need to decide what case I'm using.

This is getting complicated. I've never done two engine rebuilds near simultaneously and the possibilities are limitless since I planned to sell off the spare engine later and I do have a set of Dell's sitting on standby that came off my original engine.

For now I'm going to keep forging ahead assuming I'm using GA000099 as my engine case. But that needs machine work still to come.

Cleaning pistons is a PITA. But, these seem to be low mileage, and, in good shape so I can't see tossing them. Maybe I'll offer them up on forum or Samba if I do decide to build a 2056. It is nice to get a fresh set of P&C and not have to do all this work!

Measured skirts to make sure they aren't collapsed along with the ring grooves to see how much wear there is. Short answer - virtually none. All looking good on the 1 piston (cylinder #3) I measured yesterday. I'll do a few more today but expected #3 to be the worst due to location & generally running hottest.
