i bought an oil temp gauge but dont know where to tap into. do i need to drop the oil pan or what? i have no flippin clue on this, so any help would be sweet. the p/n is atm- 4347 from summit. i also have the oil press. gauge. my question with this is do i need to run a "y" fitting off the back of the block where the factory oil press. comes from? or do i just say screw the factory gauge and run only the autometer? im gettin ready to do the install so i wanna have everything figured out before i get into it. thanks-charlie

 

Are both of these electric gauges? I am also assuming you are talking about engine oil?

The PCM needs an oil pressure reading, so you will have to keep the factory pressure sensor. A really good location for the oil temperature is here:



This is located directly above the oil filter, you will have to drill and tap the bypass plate. The photo is my engine oil cooler adapter with the temperature sender in it. I bought this adapter from LG Motorsports but they do not sell them any more.

 

cool, thanks for the help

 

buy a deep oil pan and i will drill and tap it for you. for a price that is.

 

im pretty sure i have to drop the pan and weld in the temp sensor.

 

I installed a Autometer temp sensor into my oil pan last november. All it involved doing was dropping the pan (although a total pain in teh ***, but very rewarding and funny to have you parental drones flip out cause your front axel is sitting in teh basement hehe) drilling a large hole, and tapping it with a 1/2inch NPT thread. Now autometer gave me 2 different NPT brass plugs i used the bigger one, so i cant for sure but i think the smaller one is 3/8" NPT. As for welding it, i just used soem high-temp medium strenght loctite and have had zero problems with it for the past 3 months.

 

weld it? what the hell are you thinking?

 

yea, i was told by someone at a shop that it had to be welded in. like i said before i didnt have any clue on how to do this but now i have a pretty good idea. thanks for the solid answer. it makes more sense now. the crappy thing is that i recently did an oil change, and now i have to do it again and sythentic oil isnt cheap!

 

np on the answer, besides what you heard at the shop is probably true about welding for some vehicles, but our LSx truck engines have a cast-alumnium oil pan which is defiently easy to drill and tap but a royal pain to weld.

 

sorry to dig up an old thread but where can you tap for oil pressure?
