This is a very straightforward install. Please note that this does not cover any wiring of the senders, just the installation of the bolts. Also, I am in no way responsible for someone messing up their car. Your oil system is crucial, if your not competent then don't do this!!
Tools:
23mm open end spanner (wrench)
19mm socket and ratchet
Phillips head screw driver
oil drain pan
ramps (prefered) or jack stands
WHEEL CHOCKS
Materials:
2 modified banjo bolts
4 NEW crush washers
Teflon tape
2 quarts oil
Scott of Rx8performance.com made these bolts for me as a one off, but I believe he will be making more if there is interest. In the rx8, there is little space available next to the firewall, making accessing the oil filter a pain. Adding an oil filter sandwich adapter makes this even more of an issue. With these modified banjo bolts the spacer is not needed. One replaces the banjo bolt attaching the oil cooler line to the front cover, and the other replaces the bolt securing the line to the cooler.
DIY:
First the oil temperature sender
1: put car on ramps and place wheel chocks behind rear wheels. I found ramps to work well; since I did not drain the oil I only lost 1/2 a quart since the front of the car was higher than the oil pan.
2: remove or pull back the underside of the drivers side splash guard to access the underside of the oil cooler. I just pulled mine back, there is not a need to remove the whole thing.
3: here you will need the 23mm spanner. The bolt closest to the drivers side goes to the next oil cooler, the one passenger side is coming from the front cover. My picture shows the one on the drivers side removed; you want to OTHER one, the passenger side. We want to measure the temps of the oil before it is cooled, as it comes out of the engine. The bolt is on there tight, but with enough force it will come off.
4:Scott already had my senders attached to the bolts; if yours are not now is the time to do it. Make sure you seal the threads on the senders with teflon tape or they will leak
5: DO NOT REUSE THE OLD CRUSH WASHERS!! Buy new ones. It will save you a huge headache and possible ruined day/week. they are $0.99 each at Napa, a cheap insurance.
6: put one new crush washer onto the bolt, slide it through the oil line, put another crush washer on, and bolt it to the oil cooler. The torque spec is 24 ftlbs. NOTE: do not use any sealant/tape here, thats what the crush washers are for. using these could result in a clogged oil line!!
7: wipe off any remaining oil, but do not re-secure the splash guard.
Oil Pressure sender
1:this bolt is located directly under the A/c compressor. There is only one banjo bolt there, so there is no mistaking it. It is EITHER a 23mm or 19mm. I have seen it as either size, depending on the car. regardless of the head size, the shaft and threading of the new bolts fit perfect.
2: with a 19mm socket remove the old banjo bolt.
3: attach oil pressure sender to the new banjo bolt, being sure to apply teflon tape to the sender threading
4: put a new crush washer onto the new bolt, slide it through the oil line, place another new crush washer onto the bolt and bolt it to the front cover. the torque is 24 ftlbs. NOTE: do not use any sealant/tape here, thats what the crush washers are for. using these could result in a clogged oil line!!
5: check oil to ensure proper levels.
6: start car, check for leaks. if you have under/over tightened the bolts you could have leaks. If they are under tightened tighten them. If you over did it, replace the crush washers and try again.
7: Now you can reattach the splash guard your done!
