You know those little oil sprinklers under the pistons...

Yesterday i tried to find them.. but couldn't .. so i thought "well, i'll ask the price for new ones at my dealer and put new ones in"

... the parts clerk looked in his computer .. nothing .. micro-film.. nothing ... shop manual... nothing .. #?@%$ Those sprinklers doen't seems to be availlable as a spare part !!!??!?!

after a 2hrs search, i managed to find them.. waaa what a relief ! .. (i'm not in a mess, every nuts and bolts are stored in a little plastic bag.. etc.. but those .. i don't know.. hehe .. i wrapped them into paper-towels with engine studs.. )


So ..
1 - NEVER loose them !!!! hehe

2 - Can you ask your local Subaru dealer for availability / part number / price for that part ? Just to see if US dealers have them listed.

thanks !

morgie,

I'll see if I can find any info in the parts manual I have.

I looked in my book...I don't see a listing for the squirtres.

Now that i think about it, I forgot to look at my block to see if these have fallen out. Where are they located? I assume that feed the rod bearings???

they are bolted in the center on the bottom of the cylinders

on the 'left' beam.. you can see one bolted on the left cylinder, and one unbolted on the right one.

They squirt oil onto the wrist pins for extra lubrication and for cooling purposes.

no luck in my book either.

Any chance someone who has the oil squirters out of an engine could find out some info on them for us? The stuff I'd like to know is:

What kind of threads do they have on them?
How do they seal against the block when they're threaded in?
What does the spray pattern look like?
Do they basically function as relief valves, opening when oil exceeds a certain pressure? If so, at what pressure do they open?

If we figure out all the info on them maybe we could come up with replacements, or at least enough information that a skilled machine shop could construct replacements.

first off, why in the world would you take them out of your block when your rebuilding it?

and if you have a problem with them falling out thats becuse some one or your self have taken them out the first time. you would never need to take them out.

they cost about a 100 bucks from subaru, what type of parts dealers do you deal with....

Sometimes they fall out on their own in a high-mileage engine.

I'd take them out, but they're in there tight and I can't access them easily without disassembling the bottom end and I don't want to do that.

I removed them to avoid any problem / incident during the Overboring process .. and one of them was in the oil pan when i dismanteled (dismantled?) the engine.

I don't want the machinery to hit and broke them.

They simply screw in place with some fine threading. They seats on a little steel washer. I've read somewhere that they starts squirting when oil pressure gets higher than 35psi, to avoid a big pressure drop at Idle.


I'll use some LockTight when i'll but them back in.

Is there way to see the squirter for the very front cylinder? I can see 3 but can't see the first one because part of the block is in the way. I didn't take the pistons out so I can't look that way.

Nico, it sounds like you have located them... could you perhaps get us a part number?

Please..... This guy is full of BS...

WRXDan - I think the only way to see it would be to pull the oil pan and look at an angle. It's tough to see.

Steve

Thanks for the info, Morgie... any chance you could measure the threads and/or spray pattern? Maybe the washer dimensions?

MK, where'd you get that beautiful picture?

I know Nico sounds like hes talkin out of his ass in every post I've read so far, I'm merely giving him a chance to prove that he's not.

MK did you take that photo yourself or find it somewhere?

...Part number! The Subaru parts dept. here had a tough time finding easy things like the belt tensioner bolt. If I were to ever need these squirters I'd be SOL without a part number. They'd be flipping through their books scratching their heads for days.

There's no easy way to remove these without disassembling the block, does anyone think it should be done and the squirters loc-tite'd (sounds like a porn site)? I'm positive they've never been removed and seem tight, but an ounce of prevention ...

Steve

Don't take my opinion to mean more than it does, but I think it makes sense. If they tend to back their way out of their threads on their own on high-mileage engines, I think it's definitely a good idea to take them out yourself and thread them back in (with new washers) with some type of threadlocker.

I thought you could get to the squirters through a plug int he bottom of the block? Least that's what I infered from the FSM

They have some great articles on disassembly, head flow etc... A really nice writeup of a first impression of the engine.

MK

I have 3 of them that I will sell for...
1 MILLION Dollars... muahahaha

But seriously, VRG3, if you want to take on the burden of measruing and testing them, I will mail you one of mine. Assuming I don't sell my block, when I rebuild it I am going to cap the squirters. This was at the suggestion of Trey Cobb who claims they interfere more than they help on a high powered build. I imagine that he is correct since they were removed on the 22B

And NICO:
THEY FALL OUT!!! Read around a bit. There are several threads about this. One of my three even got crunched by the crank on the way down to the oil pan where I found 3 of them!

Matt, I would jump on that very generous offer, except that it will be several months before I have the chance to analyze it. If that kind of delay is okay with you, then I'd love to test them out.

umm... on a 210,000+ km EJ22t engine.... is it a large possibility that these oil squirters are on their way out or have already found their way to the oil pan? Crap man, what kind of failure did Subaru plan here? No way to tell until one dismantles the engine, huh?

When they fall out, does oil make its way into the combustion chamber? Or does more oil just get around the pistons? What kind of catastrophic failure can I expect from my otherwise properly-designed engine based on these damn squirters working themselves out of their threads?
