Oil pressure and Temp..
These were the two hardest!
There is so little room under there to instlall the sensor units!
Heres an idea of where it goes..
First thing you do is remove the stock oil sending unit. I used a lug nut socket, I dont remember the size but it worked perfect.
IMPORTANT! Have something ready to catch the oil that comes out when you remove the unit! It will pour a couple cups out.
With all the research I did, I found there are a couple different ways to do this. One method is to use a "sandwich adapter" which goes between the oil filter and the motor. I purchased one, and after examining it, it looke like the oil flow would have been to restricted for my likes. There was one company out there that I saw that designed one specifically to install gauge sensors.. but it was expensive. With hind sight again, I would have bought that adapter.
I went to home depot after examining the sandwich adapter to buy brass fittings to make my own adapter. I read a thread on here where the guy did it. So I went and just bought a ton of all different adapters and sizes (sure I have some left over but it was worth having the extras so I didnt have to borrow a car to go get one if I didnt have it!) I spent atleast an hour trying to find a configuration of the fittings that would work. Its a pain because you have to put them in one at time.. there isnt enough room down there to but the whole thing together then just install it. I read also that I should use the liquid teflon, so I did. The first configuration I put together, did not work. I started the car up and had a leak! I knew which one it was because there was one that I couldnt get enough torque on to get it to spin all the way around so I could get to the place where I needed to put the next fitting.
So I go back under the car and removed the whole thing, and start over. I found a new configuration (yes, its like a crazy puzzle). I put it all back together the new way, and started the car.. no visible leaks!! YAY!!!
After a couple days, the temp reading on the oil temp gauge stops working.. WTF I think..
I get back under the car and sure enough.. there was a leak, a small one, but enough to get oil all over the connection for the temp gauge. I then proceed to take the whole thing apart agian!! I spend about 2 hours this time.. really testing differnt ways to put the fitting together to that I can tighten each one. I also switch to the teflon tape, not the liquid teflon.. I think that was a big issuese. Got it all put back together and BAM, again.. no visible leaks!! I drive it for the week and check it again, no more leaks!! BUT, the gauge still isnt reading the temp lol, so next I have to find out if its the sensor or the wires.. havnt had a chance to do that yet!!
Here is the final configuration I went with..
On the left you can see the oil temp sending unit.. then in the middle is the oil pressure sending unit, then the right is the stock sending unit.
another view
as you can see there is very little room.. and I have big hands
