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.

Hasn't been a lot of action on the engine front lately. I'm not sure if that is a bad thing or not since I was largely using it as filler work during the summer surgeries until I could get back to my rusted chassis which has finally happened.

Still have a few parts that were outstanding - the camshaft being one of them.

The orginal OEM cam from this engine was still in it when I did the teardown. The cam appeared to have very little wear as compared to the others I've typically seen where the lobes with shared lifters tend to wear a deep notch at the center where both the lifter lobes overlap.

Given that I wanted to put this engine back together with as many original parts as I could I sent the cam to Elgin to see if it could be reground.

I sent the cam out to Elgin for inspection back toward the end of November. I hadn't heard anything so a few days after Christmas I decided to give them a call. The phone rang, and rang, and just about as I was going to hang up. An older guy answers.

He says, were closed for the Christmas holiday period. No worries, so I say I'll call back after the New Year. He then says, "well you got me on the phone now, what can I do for you?". I ask about the cam and right off the top of his head he says it's over at the inspection area and tell's me he's already taken a look at it, it looks really good unlike most of the 914 cam's they get and/or reject for regrinding. We have a little chat about what it came out of, what I want to do with it (street use, race, etc.) and then he reconfirms that I just want a regrind to stock. "It'll be done right after we get back after the New Year when we get back to work". (IMG:style_emoticons/default/biggrin.gif)

Now I know Dema Elgin has got to be getting up there in years but I'm sort of suspecting I talked to the man himself. Regardless, who ever it was . . . he was incredibly nice to talk with. Stuff like that seems to be getting rare nowaday's but it is why I like dealing with Mom & Pop shops (IMG:style_emoticons/default/piratenanner.gif)

Well, anyway here is the reground and parkerized cam. Looks good as new.



Now before ya'all start in on the routine of regrinding isn't as good, that it takes off part of the OEM case hardened surface, yadda yadda. I know all that.

The purpose of this GA000099 build is to put a low mileage low serial number engine back together using as many of the original parts as I can without compromising the overall durability of a engine for a hobby car that will lucky to accumulate 5,000 miles per year. IF I'm lucky and we don't have crazy hot, crazy humid summers, or snow in June. (IMG:style_emoticons/default/happy11.gif)

Next up . . . I need to get the heads checked for cracks with dye pentrant and then start thinking about new valve guides, springs, valves, etc.
