And he of course does the 6mm counterbore, etc. Pretty cool, if you want to research that.
He has developed his solution specifically for the BMW blocks. Vs. TimeSert, which has their own standard thread repair solution that they developed and then made a custom jig set for these blocks. It's not rocket science, and from my looking into it (mostly just interested in it), I was more impressed with the eBay guy's solution.
And I don't know what your skills are, but I would definitely not just assume that a guy that fixes cars for a living would have the precision touch needed to do this properly. You might be better than he would at this job.
Yes, tough break on buying it without full disclosure / knowledge. Following your story, I seem to notice more and more of these BMW I-6 engines on craigslist for cheap with nebulous descriptions of coolant leaks, etc. And I bet they are ALL like yours was. In my case, we had a brief, minor issue right before I had to do the rebuild, but I actually think the damage was done (based on service records from the PO - CCV and many cooling parts replaced in a huge dealer servicing) about 11k miles prior to my purchase, which was 28k miles ago now.
And maybe the guy honestly didn't know how serious the problem was. It may not seem so bad if you choose to believe that option vs. that he purposely deceived you.
On the condition of the rest of the engine - yes, you won't know until you get in there, or at least do a borescope / compression test / leakdown test. But on my '01 with 186k miles, I was blown away at how GOOD it looked in there.
My head was not cracked, and even the head gasket looked fine. In my case the head was just warped. So the machine shop just had to surface the head (clean and pressure test as well, of course) and did not even need to mill off enought to warrant the thicker (1.0mm vs. 0.7mm) head gasket. So I replaced with a new 0.7mm one. It apparently does not take much to cause the coolant combustion gases problem that you, I, and many others had.

All good, Oldskewel. Thank you. I may just stay with the Time Sert because my mechanic has used them and had good experience. Plus, my plan (like others I'm told) is that I'll have them use the tool(s) and then likely sell and probably recoup a decent amount. I do believe they'll bring the proper amount of precision and I'm confident this motor can be saved because it ran smooth as a kitten prior to me bringing it in. It was just that coolant consumption and pressurization in the system that made me dig as far as i have. Happy I did as this is the car my kids drive to school. It's a great vehicle otherwise, so looking forward to making the investment and having it that much better/reliable when done.
Thank you!
Ja
