Default Oil Pressure

Hey guys where is the oil pressure sending unit located on a 2010 2.5i. If you have a picture that would help.

It should be right behind the alternator with a single wire going to it.

Cool thanks, also do you know any venders that sell a tee pipe for that fitting, or any other locations i can hook up a aftermarket oil pressure sensor?

You can get everything you need from McMaster-Carr.

The plug currently installed is a 1/8" BSP thread. Most of the sensors you're going to be able to buy in the US will have a 1/8" NPT thread. So you'll need to buy 1/8" BSP Male to 1/8" BSP Male nipple, a 1/8" BSP tee, and a 1/8" BSP make to 1/8" NPT Female adapter.

Screw the nipple into the fitting in the block, screw the tee onto the nipple, screw the stock pressure sender into one branch of the tee, screw the BSP to NSP adapter into the other branch of the tee, and then screw your aftermarket sending unit into the NPT side of the adapter.

The other option (which I prefer, since it is OEM and results in fewer joints that could potentially leak) is to buy the Subaru part that goes into the oil gallery on the top of the block. Of course, that assumes you're getting a 1/8" BSP sending unit, since the OEM plug is tapped for 1/8" BSP. The PN for the plug is 11024AA210, PN for the metal gasket that goes with it is 037018200.

There's a thread on ScoobyMods that shows where the oil gallery plug goes.

Oh, and williaty, it's NPT, not NSP. He'd have a helluva time trying to find a 1/8" NSP adapter.

If your sender is NPT, that still leads to needing all the fittings to make it work. If you get a BSP sender, yeah, just screw the bitch right in.

Hold up a second guys... those ports (like EVERYTHING else on the cars) is metric. They are not BSP. BSP just happens to be close enough to work and not leak

Subaru of America has said they're BSP. BSP is also the "standard" pipe threading in Japanese industry.

Nice try, but no. BSPT (or BSP, or PT) is identical to JIS B0203. In other words, the Japanese spec "metric" pipe thread matches the British pipe thread. To quote the Geico caveman, "Maybe next time you should do a little research?"

And my spark plugs aren't metric - I use a standard 5/8" spark plug socket to install/remove them.

Where did they say that? Last time I checked with thread gauges it was metric. I can check again tomorrow.

Your correct, but I said the port. And yes I did my research a long time ago... and I just pulled the OEM port out of the block in case what I was remembering was incorrect. They are straight fine metric threads, NOT BSP. They are NOT tapered, the BSP is just close enough to seal. I think the OEM sensor is BSP, which verifies what I said initially, the BSP is close enough to seal just fine.

Good call on the plugs, but the plug threads are?

Funnily enough, the hex flats might be SAE, but the threads are metric (ISO). You have no fracking idea how much that drives me nuts.

The reason they're working out the same is that they BSP is what was adopted as the JIS standard.

Subaru has confirmed this when they were asked about it in email directly.

Hmmm, I have a gallery plug sitting on my kitchen counter (bachelor, I can do such things ), I'll have to take a look. They could be BSPP, which is similar to BSP (BSPT), but has parallel rather than tapered threads.

Oh, I know, I was just being a smartass. Oh, and the lugnuts are 3/4" (19mm) and lots of bolts are 9/16" (14mm) - if you can't find the right sockets.

My curiosity was definitely piqued by this, so I checked the gallery plug I've got sitting here. An 8mm thread chaser goes right through without engaging the threads, so the port ain't that. Neither a 10mm-1.25 nor a 10mm-1.0 chaser will thread into the port. Visually the thread pitch looks even finer than the 10mm-1.0, which would make sense for a 1/8" BSP thread (28TPI, or just a bit finer than 1.0 metric pitch). I concur that the port's threads are not tapered, but I'm more convinced now that the port is 1/8" BSPP.

Note that per this site a male BSPT (also called BSP) fitting will thread into a female BSPP fitting. The thread pitch is the same - 1/8"-28.

I believe it's .75 pitch, but it's late and I'm half guessing, but I do remember thinking it was a pretty odd size.

If I remember while I'm in front of the thread gauges tomorrow I'll verify what it is.

OK, now I'm sure this is going to cause all kinds of controversy... LOL

So according to the gauges it's an M10 x 0.9... I even found taps that size, and HERE IS AN OIL PRESSURE SENDER made by someone else (so you don't think I've gone completely nuts) that calls out the wacko thread size/pitch.

It's also a REALLY good reason why the BSP thread works (.876 pitch), as long as the mating threads aren't very long, the pitches are close enough so the threads won't bind.

As I have said before, Subaru of America was emailed with the specific question of what thread pitch those ports are. They replied that they are 1/8 BSP because the BSP family of threads is what was adopted as the JIS standard.

JIS catches a lot of people out. For instance, none of the bolts on the car are "metric". They're all JIS.

^ While I want to believe you, something's just not adding up here for me, and I wouldn't rely on what SOA says as they don't always have the right answers.

I have a REALLY tough time understanding why a non-metric british thread standard would be accepted by JIS; Japanese Industrial Standard. From everything I've seen/read (I've definitly not seen EVERYTHING) the JIS consists of ONLY metric thread sizes and pitches. If you have some kind of link that explains the BSP to JIS, I'd love to read it (like I'm not enough of a geek already).

The bolts on the car are metric, JIS just means they meet the requirements of that standard (thead size, pitch, head height, etc...).

Lemme see if I can find the whitepaper for JIS again. I found it a year or two ago when it was driving me nuts I couldn't find a M10x1.25 bolt with a 14mm head on it I'd never heard of JIS before then.

I would tend to agree with you here.

As I've said earlier in this thread, JIS B0203 is the standard that adopts BSP(T) standards. I'm not sure why, either, nor do I know where one would find the actual reference document (and even if I found it, it may be in Japanese, which I can't read.)

Swageloc publishes a couple of "Identifying threads" documents. They state that JIS Parallel=BSP(P) and that JIS Tapered=BSP(T).

Here's a quote from another fittings vendor:
Quote:
Japanese Tapered Pipe Thread

The Japanese tapered pipe thread connector is identical to and fully interchangeable with the BSPT (tapered) connector. The Japanese connector does not have a 30 Flare, and will not mate with the BSPP female.

The threads conform to JIS B 0203, which are the same as BSPT threads.

The seal on the Japanese tapered pipe thread connector is made on the threads.
From a different pipe vendor:
Quote:
Japanese Standards
PF - JIS Parallel Pipe Threads

PF threads are functionally interchangeable with BSPP. This is an old designations replaced with G.

Applicable Standards

* JIS B 202 PARALLEL PIPE THREADS
* ISO 228/1 PIPE THREADS PT 1: DESIGNATION, DIMENSIONS, TOLERANCE

PT - JIS Taper Pipe Threads

PT threads are functionally interchangeable with BSPT threads. This is an old designations replaced with and R and Rc.

Applicable Standards

* JIS B 0203 TAPER PIPE THREADS
* ISO 7/1 PIPE THREADS: DESIGNATION, DIMENSIONS/TOLERANCES
Here's a PDF listing every single god damned thread in the Japanese Industrial Standard with all the horrific math to design and build them. Below the JIS spec for taper, it mentions they're the same as BSP.

I think that's game, set, and match to BSP.
