Mines started leaking from the oil filter. Saw one video about just replacing 1 o ring. I had no clue there was 4 O rings. Going to head out to my nearest Subaru dealer to get these parts. Thank you man 🤘
Make sure you identify your engine and oil stand/cooler and make sure they match with this one. Most vehicles have just one o-ring, while certain early models had this setup. Good luck!
Yes looked on the Subaru website & confirmed to fit. Just finished it on Jack stands, it was way easier than I first anticipated. I was able to complete it in about an hour or so with cleaning & degreasing. Replaced all 4 O rings. It’s a little messy but man no more burning oil smell
I just replaced these seals on my 2007 FXT. Something that may be helpful to others: If you are doing this with the engine still in the car, you can do it without replacing the coolant by removing the 10mm bolt that attaches the crossover line, which will allow the oil cooler to dangle down with plenty of clearance to do the rest of the work. That way you can perform this repair at your next oil change. I also took the oil cooler adapter and oil cooler adapter adapter to the sink for a thorough cleaning and replacing 3 of the seals in a comfortable location.
Thanks Neal, I think my 2006 FXT needs this repair done as I found the oil filter a mess. I'm at about 139,000 miles. Still having other issues like coked up oil control rings causing oil consumption, and transmission slipping that Trans X Stop Slip seems to help, but otherwise the car runs good, the AWD in winter is unbeatable. I'm trying some Liqui Moly MoS2 antifriction 10w40 and using seafoam in oil last 1,000 miles before oil change to see if it helps the coked rings.
Subaru EJ255 Oil Cooler Gasket replace: - drain oil - drain coolant 1. remove oil filter 2. remove cooler central retainer 24mm socket 3. remove two coolant clamps from cooler 4. remove first cooler stand-off with 10mm bolts 5. remove interior retaining nut 21mm 6. replace orange o-ring on backside of second standoff 7. reinstall second standoff - exposed locating peg on reverse sits between webbing next to coolant hose coming out of engine block - tighten with 21mm 8. install blue o-ring on secondary standoff which is now on engine 9. remove and replace small o-ring on inside of first standoff 10. apply oil to small o-ring so it doesn’t pinch on reinstallation 11. gently reinstall first standoff without pinching interior small o-ring 12. reinstall all 10mm bolts 13. reinstall oil cooler - exposed locating peg on reverse goes to left of support (when facing car) in line underneath 10mm bolt 14. reinstall 24mm central retaining bolt 15. reinstall 2 coolant hoses - fill with oil - fill with coolant and follow air burping procedure
Thank you so much for this video!!! Seems I had a leak there for a while and I did the full service you outlined. Nothing ever goes quite right the first time but i eventually got it. Cheers!
I have a leakso I'm doing both. 2006 Subaru sti. Had another leak from psp . Rebuilding that . Put a cardone one for now temporarily. Your video is on the money
Awesome video man, definitely helped me save some money on my 2006 WRX TR. They were trying to charge me 400 at the stealership, but I came home threw on YT and bam your video popped up. Very informative, only way to make it a little better would be to throw up torque specs and a list of whats needed but looks like some commenters have already done that for you. Anyways thank man helped tons.
Super appreciated. Have 2011 Forester XT (with EJ255?) with 158,000 miles with a pretty good oil leak and this looks like where it might be coming from (in addition to the valve cover gaskets) and is hitting the exhaust and produces a very strong burning oil smell. I was thinking head gaskets but I don't think that's it, yay! I do all my own work. I figure stuff out eventually on my own and shudder to think what it would cost if I brought it into a shop and if they would even do this and replace the head gaskets instead.
Great video, the best one on this subject I have found. You should name this, or add to the name "Leaky oil filter fix WRX" so it shows up in more searches ;) and torque specs would be nice.
I have had an oil leak above the oil filter on my '05 Baja turbo for years. I have changed the orange o-ring on the heat exchanger several times. I didn't know that there was the pedestal and adapter plate above it with more o-rings. Thanks for the great video. Most of the videos about the heat exchanger are about deleting it. Can an oil filter be attached to the block directly without the pedestal and adapter?
I initially watched a video for this but it must have been non-turbo. So I was a tad perplexed when the dealership quoted me for 3 gaskets when I expected 1, but they didn't suggest the blue O-ring? Anyway, I I went into the job half-cocked, as I didn't realise there was the second component to remove or have a 21mm socket so had to leave it for another day. Incidentally, does the 21mm need to be deep socket? Appreciate the video!
Great video. Have you ever seen the oil cooler lines leak at the connection? I have a 2011 Forester XT that looks like it's leaking oil from the lines where the rubber hose meets the metal male connector.
@@subtledriver Thanks for the insight, plus fast reply. Ive made an order to have the XT done, overdue for oil seals. my X model is just an oil sieve a complete struggling to diagnose its source.
@@nicholassears8311 the sohc has a few possible oil leak locations. the oil cooler o-ring is one, the valve cover gasket is another, the head gasket is a common issue, less common are oil pressure switch, cam/crank seals, and rear cover plates (behind flywheel)
I noticed this when I changed the oil on my 02 wrx. Hoping it's just the o rings. I noticed it dripping down onto the filter and then slowly hitting the ground
It definitely can if it is bad enough. Mine was leaking slowly but I could still smell it on the exhaust every once in a while. Telltale sign is if you have a little droplet on the bottom of your oil filter after driving (and if the oil cooler is filthy from the leak over time).
Is there a way to delete the adapter part and just mount the cooler directly to the block? Like you said some other models have. Do I just need to shorten the coolant lines? Or will there be a clearance issue of the filter hitting the exh mani?
@@subtledriver I'd like to see that data because the thermostat only opens when the engine is getting too warm to cool it down. Which means the oil, causes by all the friction in the engine, is gonna be in to temperature before the coolant is. Therefore no "warm" coolant will be circulating through the oil cooler until the thermostat opens. So please explain your claims and I'd love to see that data.
@@claytonstill2385 the thermostat is for the radiator flow, the heat exchanger/oil cooler still flows coolant without it being warmed up, the thermostat being closed does not effect the coolant flow through the heat exchanger. the purpose is to regulate the oil temperature, and warm the oil up quickly in cold environments.

Had my 2006 sti towed , engine bay smoking . Had oil and coolant leak at the same time.
Handy video, thanks for posting. Torque specs for anyone interested.
21mm bolt - 33.2 ft-lb
10mm bolts - 4.7ft-lb
24mm bolt - 40 ft-lb
thanks for posting this info. might have to put this in the caption
@Imran Graham yea, I have been using flixzone} for since december myself :D
Is the 21mm bolt deep socket too?
@@alexwatson8851 no.
I needed the torque specs muchas gracias. Subaru did a few oops

Why did I decide to watch this vid mid-process?!? Good to know for next time, cheers.
Where is the bolt for crossover line?

Great video, just did mine hopefully solves the oil leak. Thanks
I got a Forester SG5 XT with a EJ205 and it does have the same oil cooler and cooler housing, so it seems that it came in other engines too.
I have had an oil leak above the oil filter on my '05 Baja turbo for years. I have changed the orange o-ring on the heat exchanger several times. I didn't know that there was the pedestal and adapter plate above it with more o-rings. Thanks for the great video. Most of the videos about the heat exchanger are about deleting it. Can an oil filter be attached to the block directly without the pedestal and adapter?
Do you have a video for the leaky valve cover ?
Excellent video thanks. Do you have the video explaining the change of the valve seals?
about to do this on an 06 Baja Turbo that is for sale
This worked perfectly. You're the man!
Super helpful! Many thanks! I have the same issue.
thanks for watching, and commenting!
I have a 06 forester xt and it just had the oil cooler and no plate afterwards with the additional o-rings.. is this normal?
I initially watched a video for this but it must have been non-turbo. So I was a tad perplexed when the dealership quoted me for 3 gaskets when I expected 1, but they didn't suggest the blue O-ring? Anyway, I I went into the job half-cocked, as I didn't realise there was the second component to remove or have a 21mm socket so had to leave it for another day.

Appreciate the video!
Same on the ej257 big pain oil and coolant leak
where can I
find those little hoses connected to the oil cooler?
Subaru dealer or online
Would these gasket fails cause oil to go into the coolant?
My 2009 WRX is also the EJ255 - does it have all 4 of these gaskets? Or is it only the 2004-07 that have 4?
Was there any sort of o ring around the big bolts that go in? Looks like the book calls for one.
None of the bolts had/have an o-ring.
Is this the same for a 2005 Subaru outback XT
Thanks for info ❤🎉
nice to see a world pac label on that gasket.
Great video. Have you ever seen the oil cooler lines leak at the connection? I have a 2011 Forester XT that looks like it's leaking oil from the lines where the rubber hose meets the metal male connector.
The hose is for coolant. If there is oil on there it likely came from the o-ring or above that, like valve cover gasket ect.
Same vehicle here :) Hope you got it fixed. About to do mine this summer.
@@DaveB038 yes, but had to take it to the shop because I don't have a way to refill the coolant
Is this the same for the lower models "XS" & "X" SOHC and DOHC?
only for the turbo XT. the non turbo might have an oil cooler, but it will only need the one big seal.
@@subtledriver Thanks for the insight, plus fast reply. Ive made an order to have the XT done, overdue for oil seals. my X model is just an oil sieve a complete struggling to diagnose its source.

Is it possible to find an adapter and mount the filter directly to the block and do away with the oil cooler entirely? Has anybody ever tried this?
Thanks...pretty good one handed
Excellent video, thanks for the information.
How different is the 2005 ej205?
the ej205 will only need one gasket! so much easier! Just that one fat, red o-ring, and you are good to go.
I have an 05 wrx and autozone says it requires two of the orange ones would it be this exact procedure to change them?
Is this the same for an 06 Legacy GT?
Lol “that’s what she said” @10:14
You have the torque specifications for those two bolt/nuts? I haven't found it yet on the manual I got
4 ugga duggas. honestly not sure.
I noticed this when I changed the oil on my 02 wrx. Hoping it's just the o rings. I noticed it dripping down onto the filter and then slowly hitting the ground
Most likely. Could also be cam seals, or valve cover gaskets or broken oil pressure sensor ect.
@@subtledriver are all those easily replaceable?
Does this leak on exhaust? I dont thingk my valve cover is leaking. I smell the oil burning on exhaust though.
It definitely can if it is bad enough. Mine was leaking slowly but I could still smell it on the exhaust every once in a while. Telltale sign is if you have a little droplet on the bottom of your oil filter after driving (and if the oil cooler is filthy from the leak over time).
Is this the same exact motor in a 2004 Forester XT?
I'm trying to get prepared for this. Thanks
yes! 04 forester!
Fantastic video thank you
Yeah bro my Subaru doesn’t have an adapter to the Oil cooler . Mine is straight bolted on to the engine.
You have a different version of the ej, a handful of turbo ej25 have this extra complex setup
Is there a way to delete the adapter part and just mount the cooler directly to the block? Like you said some other models have. Do I just need to shorten the coolant lines? Or will there be a clearance issue of the filter hitting the exh mani?
The oil is gonna be warm long before the coolant!! So I'm pretty sure it's only used to cool the oil not warm it up. Hence the name oil cooler
No, the oil takes longer to warm up than coolant. I have data logs on this. Thanks for the comment.
@@subtledriver
I'd like to see that data because the thermostat only opens when the engine is getting too warm to cool it down. Which means the oil, causes by all the friction in the engine, is gonna be in to temperature before the coolant is.

So please explain your claims and I'd love to see that data.
@@subtledriver
Turns out you were wrong just as I said you were.
@@subtledriver
It's called an oil cooler not an oil temperature normalizer
