Oil Temp/Oil Pressure Gauge?
I was told by my tuner that they cannot install my Oil temp gauge and it cannot be installed on the STI? Anyone hear of this or know a way around it. If I got the Pressure gauge evidently they have to disconnect the stock sending unit.
I have the Maddad Ultra Clarity Gauges

oil temp and oil pressure are two different things. you can have both installed at the same time, like i do. i removed the stock sensor oil galley plug and put the maddad oil temp one there, then got another oil galley plug adapter from subaru and put the oil pressure in the galley plug by the turbo area (take out the galley plug, stock one isnt an adapter)

Oil temp was a factory option from SOA... replacing the oil drain plug. Mind you, it's not REALLY indicative of inside-engine oil temps, but good enough...

They're wrong. There's two places on top of the motor itself that are relatively easy to access: one under the alternator where you can remove the stock oil pressure sensor and one under/near the turbo.

It just seems like a lot of work for a gauge...ugh.

A lot of work? lol you're having someone else do it aren't you? It takes me 10 minutes to install the sensor under the alternator. That dummy sensor is pretty useless anyway since it won't trip on until you've only got ~3psi of oil pressure left, and by that time it's usually too late. I'd say an Oil Pressure gauge is one of the top 3 most important gauges to have.
You could potentially have more headaches if you go the sandwich plate route as they tend to leak. I haven't heard much review on the Process West one listed, but they're all pretty much the same thing. Process West usually makes some quality stuff, but I've never been a big fan of sandwich adapters. |

Plis if you want to retain the factory dummy light you can reloacte the sensor to the back ot the drivers side head (there is a threaded plug) and extend the wire..

It may be a lot of work to install the gauge, but it would be a lot more work if you blow your engine because you lose oil pressure and don't realize it.

the subaru oil temp gauge which uses the oil pan plug location works fine but as stated above, it takes a while for the temps to register since it's reading the oil all the way down at the bottom of the pan, especially if the engine isn't really revving all that much. But it is a simple install and it has worked for me.

nice find!
I'm interested in having both oil presure and temp monitored. How would I go about not having the stock oil presure light to appear? Or is there a way to have the oil pressure light work with any aftermarket gauge? |

By having the stock wire connected to stock sensor, it actually grounds it, thus making the light functional. Without it hooked up, the wire is not grounded, therefore the light on the dash will not work like you may have thought it would.
You don't need your stock sensor if you have any aftermarket Oil Pressure gauge, like I stated above. By checking your oil level regularly and keeping an eye on the gauge, you'll be fine. |

1st off) who the hell is the guy working on the car? he can't figure this out? then he shouldn't be touching the car!!!
2nd) this is easy... if you want to retain both factory oil pressure light, and have oil temp & press. too then... -buy a brass tee w/ 1/8 (npt) male, 1/8 female, 1/8 female -buy prosport or = sender relocate. -install tee in galley under alt. -install fac.oil press horizontal facing fire wall -install braided hose from oil relocate kit -plumb braided line away from front of engine toward firewall -make sure you space/mount braided line away from any rubber hoses (as it will chew through over time) -install pressure sender -next take plug out of rear oil galley -install adaptor -install oil temp sender. not hard... especially for a shop to do. -the reason I use a sender relocate is because depending on the sender quality, there is a chance of vib's from car wearing out sender prematurely, (On our last race car we were going through one every race when it was solid mounted) You shouldn't use the sender relocate with temp though as the #'s will be off from the oil cooling in the braided hose. |

what problems do the sandwhich adapters have? i was looking to get the prosport adapter... the galley plug that goes on top near the trubo is the only plave i knew about so there is another one near the oil pan?

Sandwich adapter goes where your oil filter is. They will almost always leak, which is why people prefer to go about it using the gallery plugs. In the links I posted you will find that there is another gallery plug under the alternator that is commonly used for this type of thing and where the stock oil pressure sensor for the dummy light is screwed into.

So is it worthless to have the Oil temp gauge? Am i better off with Oil Pressure?

Both are useful for most applications. Oil pressure will definitely save your hide if you beat your car on a semi regular basis, low oil pressure at high engine speeds=bad. Oil Temp gauges are good too. If your oil gets too hot, like anything, will start to cook thus reducing the lubricating ability of the oil that can be harmful to components. I'm not sure what the normal operating temp for the oil in our cars are(?), but cooked oil can spell trouble for your turbo and bearings.

Oil gets warmed up different by make and weight. I watch my oil temp gauge every morning, when I commute with the car.
WHile the engine coolant gauge reaches that "all is well" mid-dial position in about 10 minutes, in cold weather the oil temperature doesn't start to register anything untill 3-5 minutes later. I drive the car lightely untill I can see that the oil is warmed up, at least to where there is a reading. I changed my usual 5w50 Castrol once to Mobil1 5W30, in the middle of winter, and my warmup time was reduced by almost 3 minutes. With mods on the car, this gauge can help you extend the life of your engine. The oil pressure gauge, in addition to what was said, can allow you to install an oil cooler, because you'll see right away if you've got any kind of pressure drop, in any circumstances. Nobody sells (except for Subaru for $$$) a kit that is guaranteed to not drop your pressure. It's always an experiment. |

All I'm saying is that 9/10 these things leak. Yes, I know there are people that have had great luck with them. Overall the gallery plug is a much better solution. Also, you have an 03, where these sandwich adapter plates actually fit. For 06+ it's a hell of time even getting it to fit right. You have to bend back a coolant line and a heatshield to even get the thing to seat properly. |

-I too have the process west cooler, great product! on the car since 05, tracked, and beaten only, w/ little street time, and NO leaks.
-Coop1103, to answer your Q; Both are great to know, but with out knowing a lot about your set-up and driving style/habbits its hard to say which one you need. IMO, you should have boost, egt, and oil temp. if you are running a daily driver that isn't tracked. with a "stage 2" setup (CAI, turbo back, and a good tune) this would be the most critical info. If you have an oil cooler, I would go w/ both (press., and temp.) Alot of this depends on personal pref. and Mods though... |

As others have stated above, I installed my STRI senders as such:
- Oil Pressure connected to galley plug under TMIC using remote kit from Prosport. - Oil Temp sender installed in factory oil pressure "idiot light" sensor location under alternator. This could be installed under the TMIC (w/out the remote location kit) also. Either way, keep the temp sensor threaded directly into the block, don't use a relocation kit. I preferred this to the sandwich adapter, not because I don't love sandwiches...I do, really. But I didn't want to make the filter stick out lower than it already is, and I like the fact that I can open the hood and shine a flashlight to make sure nothing is leaking. Plus, I'm using existing holes in the block so there are fewer points of failure. Seriously, the hardest part was getting the TMIC out/in. And that's not even hard. If the whole project takes an hour, you're taking too many breaks. And yes, the factory pressure sensor is fine to remove if you are replacing it with a real oil pressure gauge. Not sure about the Maddads but mine will flash the needle when it gets to a critical position, so you don't even need the dash light at that point. Someone asked about normal oil temps. Once my coolant gets warmed up, the oil temp needle starts to move and typically lands right around 200-210F when fully warmed up unless I'm really romping on it, then it'll creep up a few degrees but nothing crazy. |
