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.

Oh, and I did at least get the engine case for good old 099 picked up from the machine shop de-grease tank.

I am pretty disappointed. This block was literally covered in grease. It really didn't clean up like my other block which is shown in the lower left corner.

Sort of looks like some sort of corrosion. It does brush off though with a wire brush.

In addition, this 099 case seems to be crudely cast. There is a lot of surface flash and a sort of weld spatter look to it in some places.



I think it will clean up OK with some bead blasting and/or walnut shell blasting. But . . . that lead to other project.

My pressure pot sandblaster was already clogged up with Horror Freight Walnut shells. In my hurry to do some work years ago on the Norton, I dumped in some HF "Fine" walnut shells. Unfortunately they were far to big (like 26 grit) to go though the nozzle properly and it just made a mess. I set it aside . . . time to pay the piper.

I spent the better part of the afternoon getting that pressure pot working again and went to HF to go buy about 100 lbs of glass bead. I'd rather use Walnut shells and still might if I can find the right grade (more like 60 grit) somewhere locally.

In the end, I will block off any oil galley ports and will ultimately pull the galley plugs so I'm not too worried about using glass bead. We'll see.
