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.

Not a very productive 914 weekend. In addition to my affinity for vintage toasters, I also love vintage stereo stuff and a Craigslist deal on some speakers proved to be irresistible which consumed the better part of Sunday to go pickup.

However, I did manage to get the case bead blasted to pull off the dirt and corrosion that the degrease tank didn't get. I decided to go the glass bead route and get something done rather than screw around trying to source 60 grit walnut shells.

I know you CA guys can't fully appreciate how hot and HUMID it is in the midwest. Wearing shorts and a T-shirt leads to a full on sweat if doing any sort of activity. Now imagine suiting up in long sleeves, a respirator, and then putting on a sand blasting hood that completely covers your head. I really should have worn long pants too but instead chose to wear shorts and simply take the beating of glass bead on my legs as it ricochet's off the case. Swamp ass doesn't even begin to describe it.

Sunday was mid 80's with about 80% humidity but the forecast is for even hotter and more humid this week. Had to suck it up and get this done. I have other small parts I can do inside the air conditioned garage but this had to get done outdoors.

About 50 lbs of glass bead later:



The case cleaned up pretty well. I'll likely knock off some of the bigger casting flash that is on the top side of the engine to make it easier to keep clean. Likewise, the top and bottom case surfaces will get a light coat of silver paint to help keep clean in the future.



I taped off the oil galley ports with aluminum HVAC tape to minimize any bead getting in. Not a huge concern since I had planned to pull the flywheel end galley plugs anyway to ensure that I get them perfectly clean. Nothing worse than wondering what might be stacked up in the ends.
