brus brother Posted May 19, 2016 Share Posted May 19, 2016 (edited) 05 Outback 170,000 miles I noticed oil spotting the garage floor for a while. Tech told me I have badly leaking HGs. Would there be oil pooling in the recesses on top of the engine from HGs or is it something else? It is one grimy mess in there and I can't really see the source.

Stevo F Posted May 20, 2016 Share Posted May 20, 2016 I'm thinking headgaskets that are leaking oil will have more oily residue on the bottom of the engine. My '05 Impreza has a small amount of seepage coming from the bottom ogf the headgaskets, but not an oil drip yet. At 151K miles I think I have a bit more time before they start leaking oil steadily. I know the EJ253 (used in 2005) is known for external oil leaks at the headgaskets. Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted May 20, 2016 Share Posted May 20, 2016 No that's no super common but it is indeed a leaking head gasket. The high pressure oil passage from the block to the head is located in the top of the block which is where the oil is coming from. Quote Link to comment Share on other sites More sharing options...

Well, the good news is I have lifetime free oil changes from the dealer so I can just keep up with the service intervals and in the meantime, I can lease the car out to seal asphalt driveways in the neighborhood. 1 Quote Link to comment Share on other sites More sharing options...
Stevo F Posted May 20, 2016 Share Posted May 20, 2016 Better to have an oil leak than antifreeze- can just keep adding oil until you save up money to fix it. Shouldn't have to fear overheating like with an antifreeze leak. Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted May 20, 2016 Share Posted May 20, 2016 oil pressure sender may need to be inspected too. 1 Quote Link to comment Share on other sites More sharing options...
nickb21 Posted May 20, 2016 Share Posted May 20, 2016 oil pressure sender may need to be inspected too. ^check this first. May not be obvious with all the grime and stuff in there, but the oil pressure sender under the alternator was leaking on my 2000 and oil was pooling up everywhere on top.

Nah, that would be too easy. It is dry beneath the sending unit. The various recesses to the left of that sensor atop the engine is where I have oil puddling.

montana tom Posted May 21, 2016 Share Posted May 21, 2016 Ya , its the head gasket. I just did a HG job on a 2007 obw. Same symptom, oil pooling on drivers side. They had me diagnosis it last year and have tried living with it ... oil stink was to much for her. New HG's and its all good. Quote Link to comment Share on other sites More sharing options...

I see HGs in my future. I wonder if this external oil leak may also have an internal component that killed the cat on the passenger side... Changed the O2 sensors and plugs were fine so can't explain what caused the friggin' P0420 failed cat on the passenger bank.

mikec03 Posted May 22, 2016 Share Posted May 22, 2016 When I had leaks from the oil pressure sensor on two subarus, it was pretty dry under the sensors but pooled on the drivers side on top of the engine. So I wouldn't reject the oil sensor leak possibility. Plus, it's hard for me to understand how the oil could leak up from the HG. Maybe someone can explain.
