hey all.

im gonna be installing an oil pressure gauge here in a bit and was wondering which of the plugs on the block to use. is it the bunch circled in red or the ones circled in green? the picture isnt mine but it was the clearest one i can find that shows the front where i want to tap into. thanks!

The most accurate location is right under the oil filter boss. There is an oil pressure sensor there that turns on your idiot light when you have low pressure. People have used certain spots in the head but it wont show full oil pressure. There's a a kit around for Ecotec that uses an adapter and a short piece of braided line so you can use both the idiot light sensor, which I believe will shut the engine down in the event of starvation and the braided line relocates the oil pressure sensor to a much easier to service location. Its what I used and it works very well. They run around $90 but worth every penny

do you have a link or something for the adpater? im interested in anything that makes life easier.

if i understand correctly, with this adapter i can use the location of the the idiot sensor and run it AND my gauge off the same hole?

Yes, does both. Let me take a look when I get home a bit later

if thats the case then that sounds great!

I too am looking at doing this. Thanks for the post def helpful

Any luck on that link to the adapter?

Got the link for that adapter?

i see that maperformance sells an adapter. it says its for an evo 8/9 but will work with many other cars. im guessing itll work for ecotecs too.

if this works then all you need to add is the line into the T that they sell also to relocate the sending unit your gauge brings to someplace with lots more space.

so ive decided to put this project off until now that i actually have some time.

i got under the car today to look around and see if i can reach any of the plugs i need to use for the sensor. i bought a prosport gauge and it comes with a new sensor and not the big sending unit that used to come with the gauge. looks alot nicer and easier to install in tight places. anyhow, i cant seem to get to any of the plugs and i really dont want to have to remove the IM.

i was a reading an old thread on here about installing an oil pressure gauge and one of the posts grabbed my attention. one guy asked if it was possible to hook the sender up to a plug right on the drivers side of the oil filter housing. the pics below show where i mean.




the problem is one person stated that it works while another said that when he pulled that plug out no oil came out or nothing. my question now is... do any of you guys have an oil pressure sensor hooked up to this location and/or is this a good place to put one? seems like the easiest place for me to hook up to but obviously if it doesnt work ill just leave it alone.

Sorry I missed these responses requesting a link to the kit.Seems to no longer be available. I am able to make one if anyone is interested. I know the spot under the filter shows full pressure, the spot a few inches to the left of your finger in your first pic, but I am unsure about that location by the oil cooler

this is my one I made from an air manifold I bought which leaked cause not enough threads. I then bought an aluminum block and built my own block. Works great

which of the 3 ports in the front would you guys say is the most ideal to tap into? are they all the same? ive heard closer to the oil pump is better and ive heard further is better. why is that the case?
