Removed new carburetor, found casting defect

The LC Engineering tech suggested that we remove the carburetor, to check that the throttle butterflies were centered.  We found that the secondary was not.  We also noticed a small casting defect on the throttle body.  Further inspection found that the hole went all of the way through, so we had to return the carburetor.  I called LC and they shipped a replacement that day.  I also emailed Weber.  Weber wanted the defective carburetor, so they offered an upgrade to a 38.  We had that in our hands the next day!

Installed a Pace-Setter header

Image
When we purchased the car, the previous owner gave us a header that he had planned to install.  We looked up the model number (Pace-Setter 70-1188) and found out that it was intended for a mid 80's 22re powered pickup.  That's when we decided to use the stock manifold.  We changed our mind and purchased a stainless steel header, cheap on ebay, that was supposed to fit our '07 Celica.   Today we found out that it would not clear the steering box on one side and flywheel housing on the other. When we tried the Pace-Setter, it almost dropped right in (but the stock down pipe heat shield was just touching which kept the head flange from fitting over all studs).  Removing one (top) and loosening the other two heat shield bolts was enough to free it up.

New exhaust manifold gasket set

Image
I knew there were a few exhaust manifold mounting studs missing, most likely with stripped threads on the aluminum head.  I replaced all of the studs except one, and had to repair three holes with M10 x 1.25 heli-coils.  With the new gaskets and a good mount, the exhaust manifold was no longer leaking at the head.  Unfortunately, there was another leak at one of the air pipe flanges.  In order to replace that gasket (which was new) or to add another for more thickness, we would have to remove the manifold again. 4 out of 7 studs = leak I brought the manifold to a local auto parts store with a machine shop, for resurfacing The center stud was a little questionable, so we added a jam nut for now

Fixed the turn signals

Image
When we purchased the car, it had no working turn signals.  We checked for a blown fuse, bad lamps etc and then drove home from Seattle without turn signals. I found a schematic online and used it to isolate the problem down to the flasher / turn signal relay, or a wiring problem after it in the circuit. The relay had a very questionable repair at some point, because the output connection was a very thin piece of steel or tin.  After opening it up, I found the repair was not soldered -- only glued! We will see how long my repair lasts...
