A leaking rear seal can often be tightened to eliminate the leak.....A lot of people prefer to work with the original seal rather than put in the Felpro replacement. Don't exactly know how it is done, but mine was "tightened" and it is no problem.
You must find a member or shop from this forum to do the crank sensor. Anyone else will take too long and be too expensive, and may mess up the gapping of the sensor.
The water-pump is in the same category but can be done by a regular shop, but it will be expensive (maybe $300.00 or so from a regular shop). My advice would be to get the parts yourself from Shosource or Rockauto, because the regular shops can't find the parts.
If you do the water pump soon enough, you may get away with not doing the crank sensor.... up to you. But if you are stuck, cant find a shop or shomember to help, and like to gamble, it is one way out.
I bought my car with a really leaky waterpump that the previous owner had stopped up with stop-leak or some other product. People will tell you it will foul up your rad or heater core.... not true. I never had an issue with it, but I did drain it all out when I fixed the pump. So if you are desperate, it can be done temporarily this way, until you find a helper to do it correctly.
I got both mine done (water-pump and crank sensor) at a shop that had done it before, and that would be my advice. But I had the luxury of not being stuck.
