I've been trying to figure out how to install these gauges. Boost and AF seem simple enough. I'm a little stuck on installing the oil pressure gauge.

I've heard the Greddy sandwich adapter is the easiest thing to use...

However what are my other options? Can I use the stock pressure sensor? Can I T into something?

I understand how to power the gauge but getting the reading is what doesn't make sense to me.

Thanks, JOE

T in at the block, where the stock pressure sensor is. Will post a pic in a few.

Is it an electric gauge or a mechanical gauge?

enjoithis

digital

paulky_2000

appologies....

I actually meant the means in which the guage it'self will recieve the signal from the engine.

A mechanical oil pressure gauge will usually have a tiny plastic tube that the oil will trave through, thus creating pressure....just like a boost gauge.

An electric gauge will utilize a sending unit and electric signals (ohms?) to influence the needle...or in your case, the digital readout.

If this isn't completely accurate, somone please correct me!

T it using a 1/8 npt fitting

enjoithis

yes, i didnt want a tube of hot oil running into the car... its a digital sensor with wires running inside.

this is what i have http://customizemyscion.com/store/in...roducts_id=146

This is correct. just piggy-back the factory sending unit by using a T-fitting. Its a part you can easily pick up at an auto parts store or even Lowes.

Oh yes...and use liquid thread sealer, if possible.

aen

you shouldn't use sealer, i wouldn't want anyof that stuff making its way into my engine

paulky_2000

I meant in lieu of thread tape!

I used a yellow teflon instead of red rtv, no leaks so far

coryjames

red rtv should never be used as a thread sealer i have seen this many times and its not smart i would use teflon tape and or pipe dope or teflon paste never red rtv

aen

hahah teflon tape is for sure bad, the best thing you could use is white teflon liquid sealent

but i still wouldn't...eitehr way you probably wont' mes something up unless you out a glob in the damn hole.

regular white teflon shouldnt be used on oil line and fuel lines, they get destroyed. Yellow one will withstand petroleum

coryjames

i have used white tape for all my needs i do hvac im around alot more corrosive chemicals then one could believe Teflon holds up pretty well but as with everything proper use it what will get you the final result

omg.... stupidest effing thread ever.. i finally realize how this works.. so easy..


I was going to ask what goes into the T because there will be an opening and the piece that I was thinking of was the wire which nuts onto the sensor. For some reason I totally forgot about the sensor. Obvioulsy you just T into the block and stick the sensor into the T and connect the wire to the sensor to transmit the signal....

I cannot believe I didn't see this earlier.. So damn obvious that it makes me sick going into my senior year as an engineering student...

Thanks everyone, JOE

aen

it's ok, i forgot to close my oil cap after changing my oil

we all make mistakes haha

paulky_2000

I've done that. What a nasty, smoky mess!

Also left off radiator caps, tools under the hood, oil buckets under the car and lowered the jack, backed into another one of my cars in my OWN DRIVEWAY....

I could go on, but I think that's enough to establish me as a complete dumbass!!

aen

i backed into my car with my brother's car

thats why i have a towhook in the front of my car! i leave tools under the hood all hte time. if i hear rattling that's the first place i check.
