I have a 2009 Outback 2.5i with the H4, non-turbo with 160K miles on it. The head gaskets have probably been blown since I bought the thing at 117k miles. There has always been oil on the bottom of the oil filter when I go to replace.
I check the oil level regularly and really don't have to top it off that much between my regular 5K mile change intervals.
I was replacing my catalytic converter this weekend and was able to confirm drop of oil forming on the bottom side of the engine where the head meets the block.
The engine oil is always clean, no forbidden milk shake, no overheating. SO my question is: How risky is it to keep operating like this. It is my daily driver, we take it on road trips, etc. Is there a high risk of this external head gasket leak turning into an internal one? Looking for a gut check from those with anecdotal evidence. I've love this car and have put quite a bit of money and sweat equity this year with a timing belt kit, rear wheel bearings and now OEM cat. Would love to give myself a little more time to save up for a cherry picker (or potentially professional) to replace the head gaskets.
