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.

Burning the late night oil.

So many other obligations for the weekend pushed machine work on GA000099 case into the late evening as the only means to get something productive done this weekend. The past couple weekend have been occupied with getting MIL moved into an assisted care facility after a fall. Nothing broken but her days of living alone and 90 miles away are over.

As predicted based on initial measurements it took 0.010" of clean up to get a completely clean cylinder deck surface. 0.005" pretty much cleaned things up (recall I could get a 0.004" feeler under my straight edge) so I feel comfortable about the work. The last 0.005" is pretty much just to ensure complete flatness and to easily coincide with the availability of cylinder base shims in 0.010" thickness.

Here are the final pic's of the Cylinder 1/2 side:



And the 3/4 cylinder side:



Need to follow up with my powder coat guy. Engine tin is past due It should have been complete a week or two ago. (IMG:style_emoticons/default/dry.gif)

Also need to get my own butt in gear. I need to get the original cam out of this engine sent to Elgin for a weld and regrind back to stock. There isn't a terrible amount of wear on it but there is some on the lobes that share lifters.
