nitpikker247 Posted September 23, 2015 Share Posted September 23, 2015 2005 Baja Sport. I changed the valve cover gaskets and spark plug seals in May 2015. Oil was Slowly dripping from the oil filter. No oil stains, it drips on the exhaust and burns off. Strong smell when I'm at a traffic light (idling). New gaskets look good. Filter was tight; changed the oil and filter, just to make sure. The plate where the filter gasket meets is not damaged. It's Still leaking! Anybody have a similar experience?!

Fairtax4me Posted September 23, 2015 Share Posted September 23, 2015 If it has the oil cooler, the o-ring above the cooler is probably leaking. 22mm socket I think for the post in the center then the cooler should be able to pull down enough for you to wipe everything dry and put the new o-ring in. Get the o-ring from a dealer. 2 Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted September 23, 2015 Share Posted September 23, 2015 yeah, 22mm or maybe larger , probably deep socket for that threaded tube in there - you might try just tightening it first but, I think replacement is not too difficult. 1 Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted September 23, 2015 Share Posted September 23, 2015 Head gasket or wrist pin access plug behind the timing cover could be leaking. Quote Link to comment Share on other sites More sharing options...
nitpikker247 Posted October 10, 2015 Author Share Posted October 10, 2015 Thank you All. Will try to report. Hopefully easy fix Quote Link to comment Share on other sites More sharing options...
idosubaru Posted October 11, 2015 Share Posted October 11, 2015 Oil cooler post is 24mm deep socket. Crack smokers, be nice to not need one size for one part - should have just made it 22mm like the crank bolt. Quote Link to comment Share on other sites More sharing options...
eddi887 Posted February 9, 2017 Share Posted February 9, 2017 Hi All, I realize this is somewhat of an old post, but I'm just about to replace the O rings for the oil cooler on my 2005 Subaru Baja Turbo. Does anyone have the procedure, and the torque specs for all the bolts? I'm planning on replacing all the O rings, and it looks like there are four all together. Thanks....Jeff Quote Link to comment Share on other sites More sharing options...
86 Wonder Wedge Posted February 9, 2017 Share Posted February 9, 2017 There should only be one, large O-ring between the oil cooler and the block.... Red, retail is about $7.... Quote Link to comment Share on other sites More sharing options...
idosubaru Posted February 9, 2017 Share Posted February 9, 2017 this: There should only be one, large O-ring between the oil cooler and the block.... Red, retail is about $7.... it's the orange on on this cooler, pictured here: https://www.amazon.com/Subaru-21311AA051-Oil-Cooler/dp/B00IGZPVDC don't really need torque spec's if you're comfortable around Subaru wrenching, though i understand the desire. i'd get a FSM - even an EJ25 FSM, they're free all over the place and will cover most of the same common parts - timing bolts, covers, oil cooler, etc. Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted February 9, 2017 Share Posted February 9, 2017 The turbo Baja runs a 2 piece oil cooler. There are 4 orings inside that have to be replaced. You will need a 22mm deep socket, 24mm deep socket and a 10mm standard depth socket. 1 Quote Link to comment Share on other sites More sharing options...
86 Wonder Wedge Posted February 9, 2017 Share Posted February 9, 2017 I COMPLETELY forgot about it being two-piece. Good call Caboo. However, is the block-to-adapter seal leaking? or the cooler-to-adapter seal leaking? 1 Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted February 10, 2017 Share Posted February 10, 2017 Might as well do them all while you're there. They all get hard and brittle as two of the 4 are standard black rubber. The other two seals are the orange ones, one between the cooler and the bottom adapter and between the block and upper adapter. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 11, 2017 Share Posted February 11, 2017 You may find that the head gaskets are leaking onto the cooler/filter. This is typical of those models. The coolers leak too. GD Quote Link to comment Share on other sites More sharing options...
GreaseMonkey03 Posted February 11, 2017 Share Posted February 11, 2017 What oil filter are you using? Aftermarket oil filters are notorious for leaking on these for some reason. So much so that valvoline created a Subaru specific filter exactly for that purpose. If there's no oil above the filter itself, that's the first thing I would suspect. Use either the valvoline or a Subaru filter if that's where the leak is coming from. I don't know why they leak, but I know for a fact that they do. Maybe the gaskets can't hold up to the heat? Your guess is as good as mine. Quote Link to comment Share on other sites More sharing options...
SuperBrat Posted February 11, 2017 Share Posted February 11, 2017 Nice to know ...my Baja also has a small filter drip........... Quote Link to comment Share on other sites More sharing options...
lostinthe202 Posted February 12, 2017 Share Posted February 12, 2017 Oil cooler post is 24mm deep socket. Crack smokers, be nice to not need one size for one part - should have just made it 22mm like the crank bolt. Makes you wonder if the engineer was just too lazy to change the defaults in whatever CAD software they were using, or, I suppose, more likely the engineer was following the SAE/ISO rule book without thinking about working on the vehicle in practice. The best engineers are the ones that have actually had to work with their hands Quote Link to comment Share on other sites More sharing options...
GreaseMonkey03 Posted February 12, 2017 Share Posted February 12, 2017 Probably because the post size required for sufficient flow wouldn't fit a 22 mm bolt. Maybe? Don't know. I'm not an engineer for sure. I do know this though, next time I have to remove a supercharger and manifold and all of the air and coolant plumbing just to change a knock sensor, or have to spend 6 hours trying to change an O2 sensor, I may put an ad on Craigslist to find a random engineer so I can beat him to a bloody pulp and get my frustration out.
