Re: oil leak on top of motor

Thanks to the more experienced folks for chiming in. I had oil pooling on top of the motor + a code for a bad knock sensor, at ~150K miles on my car. Both were cracked. I assumed their replacement was a given while the intake was off, at least on any motor with 100K+ miles. But maybe that was just my car.

And I didn't know about the IRIS O-ring at all! Oh well, maybe next SVX.

Re: oil leak on top of motor

Got the o ring for the IRIS. Is there a diagram on the site that shows where this goes?

Under the intake manifold.
If you have the alternator removed you MIGHT be able to replace it while the intake manifold is still installed on the engine.
Be prepared to use words that would have your parents wash out your mouth with soap.
It is only four 12mm bolts (outside wrench diameter) and one link to deal with, but what a PITA!

Yes, I recommend you pull the intake manifold and replace every vac line under it, as they will likely be brittle. Just be very careful with the plastic nipples they tend to break if you look at them wrong.

While the intake manifold is off the iris valve is much easier to deal with.

Re: oil leak on top of motor

I think this shows where the IRIS O ring goes. Found it in a post from LetItSnow.

Re: oil leak on top of motor

In the above picture the I.R.I.S. valve, (not the IRIS check valve) is next to the can of WD-40, sitting on the paper towels.
Oh, and IF you take off the intake manifold its a GREAT time to change the $3.00 PCV valve.





I might have said this before, but, hey, I'm old...

Re: oil leak on top of motor

So, when u take IRIS valve out to replace o ring, do you do anything with the valve while it's out? Clean or lube?

Re: oil leak on top of motor

Cleaning it would be nice.
As far as lubing it...
The shaft pivot points get no lube, other than engine oil vapors from "The Factory".
If it is worn to the point of noticable wear, maybe you should just replace the IRIS valve assembley,



(but it's like $300.00)

Re: oil leak on top of motor

PCV valve was a huge PITA. I think mine was overtightened, or the aluminum fused with the metal, but there was no way I was getting mine off without the manifold off and some major elbow grease. A side benefit: the SVX runs happier with less vacuum leaks after replacing the brittle/cracked hoses . Really long needlenose pliers go a long way in this project.

So I have the PVC valve, the knock sensors and the IRIS o ring. Plan to replace vacuum lines too. I did not order a check valve. Is that a likely item to fail?

Hoping to get started. Should I order the check valve too?

The I.R.I.S. check valve is about $25.00 or so,Subaru part #16195AA030
and can EASILY be broken.
If it has a crack in it (quite common) then it will fail.
They can be replaced without removing the intake manifold.
I use 12" long hemostats ,
a head lamp, cause my eyes are old...
lift the car seversl feet in the air, again cause I'm old...
But, HEY, while you are down there.
