Finally had a chance to make some progress on the RX-7 this past weekend; not much but its a start! Savannah has moved from the parking lot outside my apt to my fiance's parents garage, and is up on jack stands awaiting a new water pump, replacement of some of the studs holding the oil pan & brace on, new brake rotors, new LIM to block gasket, turbo blanket & downpipe wrap, and some welding on the exhaust (plus I'm sure I'm forgetting a couple things on the list).
Anyway, dove in to drain all the fluids and pulled the water pump, and one of the bolts holding it on was missing! Its was the one in the image below with the tap sticking out of it, since the threading all the way back in the front iron was completely stripped! I'm hoping that I'll just be able to tap into the aluminum front cover with one size bigger to hold the water pump on without causing any other problems - id really prefer not to take the front cover off to re-tap the front iron and deal with possibly dropping the thrust bearing in there etc. The tap I've got should be long enough to get in to the iron a bit so I can use a larger dia bolt, which is the plan right now.
Also, for the previous month I've been battling with water soaking the carpets whenever it rains - I've replaced the seals along the sides of the targa top, the window bottom seals (to the outside door skins), readjusted the stops for the windows so that they'll meet the top seals in the right spot, messed around with the pockets in the top right behind the doors (they weren't catching all the water running down the back of the windows and top corner of the door, allowing it to run down & pool behind the seats), and sewed up and hopefully re-sealed a couple holes that sprung up at the rear corners of those pockets. I now know WAY too much about how rainwater is meant to be handled & directed through the car. Here's one of the holes at the back of the pockets, seen from inside the car under the headliner.
To seal it up, I cut out a patch from some vinyl left over from re-covering the scooter's seat, coated that with E-6000 glue (sticks to vinyl, plastic etc, stays pliable when hard, waterproof etc), stuck it over the hole, and then sewed around the border to help anchor it in place. I forgot to get a picture of the completed repair, but will try to next time I put the top up.
