So, been struggling a bit to get a chance to actually work on the car, FINALLY had a combo today of time and not-freezing-temperatures in the garage.

Good news is that it appears I've managed to get the carbide burr out of the hole. Looks like the automatic center punch idea was the trick (Thanks, I believe it was Bruce). A few solid chunks came out and once I saw that I was actually making dimples in the bottom of the hole I knew something had changed. Cleaned it out and used a scribe to feel things out and it's got the profile that burr would have left, and no signs of the burr itself. But it seems there's still some of the old ez-out still in there, so I can't get at it with a drill bit JUST yet.

I've got another couple of those burr's on the way, since I know they can get through the ez-out. I just need to be more careful and not lay into it with so much pressure. It's a burr not a drill. I'm sooooooo close to being able to have a bigger ez-out grab into the bolt.

Please understand I don't mean to sound rude, sarcastic or mean, but no matter how I word it, it all comes out sounding that way. The following is meant in the spirit of honest discussion.

To wit: I'm actually kind of surprised. It's been over three weeks since the last update, and from your previous posts, I was given to understand that time was tight enough to have already been at near-critical levels even before the bolt broke. By this point I expected the next update was to announce the bolt was out, the head reassembled and you're back to testing and tuning.

As I understood it, you had or have a fresh, new motor you could drop in, but didn't think you had the time to do the swap. Similarly, the option of taking the head off and having the bolt removed professionally, was also deemed as taking too long.

Now, I understand that there are financial factors, weather and 'free time' factors, and certainly "level of enthusiasm" factors (lord knows there have been days I couldn't drag myself out to the shop if you put a gun to my head- especially if a job is being particularly frustrating) but I still think I'm missing something.

Again, I don't mean any of that in a disparaging manner, I'm genuinely curious about the situation, and plan to continue to support the race as best I can.

Doc.

It's been a hectic few weeks, and all of this is just bad timing in relation to my pinball business. I've got a major trade show coming up next week, and I've been struggling to get inventory ready for that. Doesn't help that every time I think I'm getting ahead... I get fairly large orders and there goes another day of progress. So that's been sucking up a lot of my time. Then came the bomb we dropped on ourselves about moving about 100 miles south and getting new jobs. Again a big chunk of time went bye-bye there just dealing with realtors and interviews, of which we haven't even landed new jobs or actually moved yet.

I did come real close to swapping motors or the head, but there's two big roadblocks there. One is that the other engine is currently mostly disassembled, and I'd need to at the very least grab a gasket set and put that together. I'd also want to probably do crank and rod bearings while it's on a stand. But it's also juuuuuuuust different enough to make it a pain in the ass. Compression is higher and the intake manifold bolt pattern is different. So I'd have to source either the correct manifold or an adapter, both of which are additional cost, and I'd essentially have to go straight to the megasquirt instead of using the factory ECU. Though I do have a line on a replacement head of the same time should I need it. I'm just absurdly paranoid about trying to get the 30 year old exhaust manifold bolts out intact.

Throw in a foot of snow on a couple occasions, running out of wood for the garage stove, and unplanned family obligations.

That and I've worked on a couple aspects of the car instead of this f'n bolt, which I haven't covered yet, just to keep my sanity intact. So the project hasn't been languishing completely I just haven't covered this particular part of it.

Well, "good" in a fairly loose definition of the term, of course.

But at least it hasn't been an issue of "go sulk inside instead of work on the car" or something like that. (Which, as I said, I'm fully guilty of doing myself, on occasion. )
