autometer oil pressure gauge

[asd_gst]

to start sorry if this is the wrong section to post this in.
but i have the autometer shortsweep oil pressure gauge EXTREME PSI : Your #1 Source for In Stock Performance Parts - Auto Meter Ultra-Lite Gauge : Oil Pressure 0-100 PSI. will teh sending unit that comes with the gauge just screw into where the stock sending unit goes? my stock one doesnt work, i have this gauge but i was wondering if its the same thread as the stock sending unit. if its not how would i put it in? please help i have no clue what my oil pressure is right now which kinda sucks. any install tips?

Some people jam it in there and are fine, and others that try this end up cracking the oil filter housing. The threads in the oil housing are 1/8 BSPT. The sender is 1/8 NPT. To properly install it you will need an adapter found here:Adapters and Bushings: Bushings - 1/8" NPT Female x BSP (BPT) Male - egauges.com
That will work, others also remote mount the sender from the engine block to prolong the sender's life. It is known that engine vibration kills the sender fairly quickly.

I have the same gauge and didnt use an adapter. I just screw it right in and used some permatex thread sealant. Just dont tighten it too much or you will crack the housing the like the last person said. Just tighten in and start the car, if it leaks tighten it until it stops.

this may sound stupid but what you mean the engine block? sending unit is on oil filter housing

 

[Gstclipse69]

The vibration from the oil filter housing/block will kill the sender in time. Some people prefer to mount the sender away from the oil filter housing by the headlight or power steering reservoir. You would need a fitting for copper/stainless steel line and just run a line to wherever you would want to mount the sender.
It is discussed here http://www.dsmtuners.com/forums/new...merged-oil-sender.html?highlight=oil+pressure
Here is an example of a kit designed for such:Remote Oil Pressure Sender Kit [RPS1] - $40.00 : Jay Racing

oh ok cool thanks i understand now

 

[matt98eclipse]

I installed my autometer oil pressure sending unit into the oil filter houseing and havent had one problem with it. It screwed in just fine. just make sure you dont over tighten it.

Just something to keep in mind is that the autometer electric sending units are not designed to see pressure over 100psi. According to autometer if the unit sees over 100psi it will damage the sending unit. To do it the best way, buy a mechanical guage and buy yourself 7' of braided line and you are good to go. Russels makes a easy and complete kit. Russell Performance - Nitrous Lines You can get it in different sizes and variations.

Actually the OEM oil pressure sender is a 1/8 Brittish pipe thread. There's just enough difference between the two that in order to do it right you need an adapter. However, some people just screw the NPT version in with out problems. IMO, just do it right.

I dont think mitsubishi motors would make an oil filter housing with a NPT??

You shouldnt see over a 100psi if you port the relief hole in the oil housing. 100psi is way too much.

 

[asd_gst]

how do you port the relife hole?

Well I guess that mine and many others I know see way too much oil pressure, But what do I know.

There are a few threads on this. You just have to grind that hole open a little more. A lot of people say its dangerous cause you could open it up too much and cause damage. Check here for some pictures.

 

[erald01]

The easiest way is to conect it to the filter housing. I have done it twice before and my readings have always been accurate.

 

[asd_gst]

well what is the point i still dont understand why it needs to be ported most people say they do it when they have 2.4 no oil squirters, dont the 4g63t come stock with oil squirters?

 

[Burnett03]

I've never used a british to american adaptor and have never cracked a housing or had a leak.. I use teflon tape.

Actually, most people have to port the oil relief hole when they remove the balance shafts, as that causes higher-than-normal oil pressure in most cases. Oil squirters have nothing to do with it.

 

[matt98eclipse]

I am also one of those people who see's alittle over 100psi at WOT.

 

[Spoolin98]

You should only have about 10psi of oil pressure per 1000 rpms. I ported my relief valve because I have no balance shafts, I see no more than 80psi.

For example, my friend didnt port his and removed his balance shafts. He hit around 100psi on a cold start at idle, and more than that at high rpms when warmed up. Shortly after that he blew out some oil gaskets, one being his oil filter housing gasket.

 

[matt98eclipse]

Thats crazy cause i have had my car for over a year now like this and not one gasket leaking except my stupid oil return line. Knock on wood .

 

[droppinbottom]

Probably 25k done over about 3 years on this motor without balance shafts and on cold starts it sees right around 100psi and can see as high as 120psi. Normal operating pressure is right around 75psi at cruise for me.

 

[Spoolin98]

Thats really high oil pressure...
Im not sure if your motors were freshly built or if you just removed the balance shafts with xx,xxx amount of miles already on the motor. But that may have played a role in why my friend had so many leaks, his motor was brand new.
All I know is the oil filter housing gasket leaked, we pulled off the housing and ported the relief valve and put a new gasket in. It hasnt leaked since.

I run a thick oil, 20w-50, and on a cold start I see about 50psi. Once it warms up it hangs out around 20psi, at WOT no more than 80psi.

Obviously you guys have seen no ill affects from seeing 100+psi, so thats a good thing. But I would still port the oil relieve valve and lower your oil pressure. Thats just my opinion though...
