this will be my final comment(s). I was polite and cordial throughout the whole process. Here are some facts:
I'm picking the engine up today. My shop says I got FOUR used pistons. See how this goes?
My oil pump was like new, and I wanted it back as a spare. When I mentioned it they said they put gaskets & seals in them. This was a "goof" I guess, since newer pumps are re-buildable but EA82's get new ones. So my "demand" was just a request that they be sure to use mine, which they did. Later during the "warranty" process this came to light and I asked for the new pump I had paid for, which I got.
So, in summary: EA82 rebuilt without new oil pump as result of "misunderstanding" (?). No/low oil pressure on start-up. Returned for warranty diagnosis?repair with request for upgrade to new heads for more $. Got it back with new oil pump but original heads- raising ? of what they actually did. CCR agreed to pay my shop to complete the "warranty" work. My shop found ground crank with standard bearings, used pistons et al. CCR gave complete refund.
No, Emily, I kept my word- you won't hear from me again. This part is my civic duty, as it were.
I think they did good work in the past. The "Net" suggests my experience was not unique. Caveat emptor...
