2 things, 1) what size wrench do you need to take off the oil sensor on the back of the block, and 2) can anyone tell me how to install the 310 injectors i have. any input is helpful, im in a crap mood because nothing i have fits right. thanks for all the help.

this would easly be found in a search.

theres a socket at the auto store called "oil pressure sending unit socket" or 1 1/16 deep well.

and you have to,unbolt and disconnect the fuel rail for the injectors. theres 2 13mm bolts that hold it onto the lower intake manifold. take those off, and the fuel feed line (2 8mm bolts) and pull the rail out. the injectors are held in by retaining clips on the rail, and 0-rings in the manifold.

thanks for the help, and yes i searched but i thought that you could just use a wrench to get it off but it sounds like not alot of people had any luck with that, so ill get the socket.

i used a simple wrench and lots of PB Blaster.
