Paid the taxes 2013 today....That means, among other things, that the motor rebuild is on....Good thing, too. The 062 heads are already done and sitting at the machine shop.

I'm going to pull the hood and send the hinges out for a rebuild. I''m planning on pulling the trans and engine together. Then, I thought I might to pull the serp set up and lay all
the chunks aside. Much like I did when I screwed up last time and had to pull the motor after the initial install.... because the freeze plugs only *looked* good.

Then, I thought, "After draining and disconnecting most everything, why not pull the whole thing, serp set up and all?"

Question about the A/C :

Is it a big deal (environmentally or otherwise) with 134a if I just crack the a/c lines and let the V/A gas loose? Then go back after the transplant and evacuate and then re-charge?..
...I have to pull the lines anyway, since I have the gift of a nice, freshly a black anodized, ball-milled firewall VA block-off plate I'm going to install.

If there's good reason not to pull the a/c lines as they sit, I'll head over and have the gas trapped at the a/c place.....for $100.

If not, I'll let'er rip when I get to (re)pulling the motor.
