is there a place to drill/tap for a 2nd oil pressure sender?

ttocs · Jul 11, 2015

I currently have gauges set up to read both the oil temp and the oil pressure in the fittings sticking out of the block like I have seen everyone else do. I recently added a spot in my lower intake for my aftermarket gauge sender to go right next to the stock sender so it will remain active just because I hate seeing it dead. Is there a spot that I an do the same for the oil senders?

As far as i know you can just T of the sending unit. .

ttocs · Jul 11, 2015

right and that is what I have done but I have an oil temp and pressure sensor now. just looking to make things a little cleaner/simpler rather then adding another T to it. I just have no idea where the oil flows through to know if its possible.

Not sure on the 5.0 but on the 4.6 you can get a oil filter relocation and some have a port for a sensor

hmmm I think I do recall seeing those now that ya mention it. Just need to check clearance but good suggestion.

I have an oil relocation kit for my 5.0 that has 4 ports on it - 2 are used for the oil in/out to the filter, and the other 2 ports are available for whatever you want. I will be running my oil temp and oil pressure sensors off these two ports.

cool the sandwich plates seem like a simple way to do it nice and clean. Now with that plate comes the option to run an oil cooler. Is there anyone on here that uses one by chance? Seems like it would be good to have as I noticed on long trips that it would slowly keep rising although I can't remember what it got up too....

The kit I have isn't actually a sandwich plate but a relocate kit for the filter. The part that has all the extra ports on the filter portion of the relocate kit. I don't know if there would be enough room where the stock oil filter goes to run a sandwich plate with sensors hanging out of it. You might be able to run some hose and mount the sensors "remotely" though

Just get rid of your stock oil pressure sending unit

I know its tight there and I wondered that myself. Another reason I considered the oil cooler as if I am going to run lines for a remote filter it just seems like it would be a good idea to do a cooler as well(with a thermostat). Sure more money but at this point....

Right that is what I said I am currently doing but the dead gauge just bugs me even though I know its basically useless.

Ground the wire.... voila.. no dead gauge

To clarify.. you don't need an oil pressure switch for the stock oil pressure gauge to read normal. All that 6 psi switch does is provides ground for the circuit.

So all the factory gauge is doing is showing that the pressure is higher than 6 psi? Guess a real pressure gauge just moved a little higher up on my priority list. That's no better than an idiot light....

ttocs · Jul 12, 2015

yes that is correct its basically just an idiot gauge.

Worse than an idiot light.. lol.
1. You think you have a working gauge.
2. You can have serious engine issues and the gauge reads normal.
3. When the gauge freaks out you think you have issues when you don't.

I just realized this is in the 5.0 section. I use tapatalk alot and dont pay attention to what section things are in most times. Is the gauge funciton still the same for a 4.6? I'm assuming it is since when I almost stall the car I notice the gauge drop very quickly to the bottom and come immediately back to its normal "mid" location.

Also maybe a dumb question here to as I'm more familar with GM stuff but on most GM's the oil pressure switch will kill the fuel pump relay at low/zero pressue. Guessing this also isnt the case if theres only one wire coming off it? Reason I'm asking is if its basically an idiot light I'd personally rather leave it dead so it forces me to look at the real guage instead of giving false info. I also want to add a real coolant gauge so I know what temp its running instead of just "normal" lol. Thanks!

I don't know on a 4.6 brotha.

Scott, don't use the pressure location for the oil temp sensor. You need t put the temp sensor in the oil circulation. Either in the oil cooler line (if you have one), or in the pan. To get a good reading anyway, not sure if you have a aftermarket pan but a lot of them have a temp sensor provision.
