Where is the oil leak on a Subaru?
The camshaft sprockets are behind the timing belt cover. These oil seals can leak with age and mileage, especially the earlier black colored seals. The later brown colored seals are more resilient.
What should I do if I have an oil leak in my timing cover?
When it comes time ALWAYS do timing belt, drive belt, all seals, re-seal the oil pump tensioner, idlers and water pump. Do all that and you never have to touch the front of the engine for another 105,000 miles. The oil pump runs between 15-60 (or is it 80) psi, so it doesn take much to get oil all over everything.
Is the spark plug on a Subaru H6 leaking?
If you were going to “guess” it would make the most sense to start with the two items that leak on just about any H6 (or H4 for that matter) with any age/miles. The spark plug job on this motor is a nightmare – but only takes 20 minutes with the valve covers removed.
Why is oil leaking from the timing chain?
Thanks so much for your time! Timing chains have engine oil lubricating them, so the leak is probably just the oil normally in the timing cover area. Camshaft seals are not routing maintenance, and only need to be replaced when leaking. But there is supposed to be oil in that area, so it’s kind of a moot point, I guess.
Where are the oil leaks in a Subaru?
The common Subaru oil leak problem areas are: 1 Rear of engine, PCV baffle plate 2 Front of engine, crank seal and piston access plugs 3 Valve cover/spark plug tube seals

Can a timing cover be replaced on a Subaru?
However, research and calls to Subaru mechanics revealed that a seep/leak could require replacement of the timing cover, resealing of the camshaft carriers or repair of the valve cover gasket – all expensive repairs.
The camshaft sprockets are behind the timing belt cover. These oil seals can leak with age and mileage, especially the earlier black colored seals. The later brown colored seals are more resilient.
When to replace the oil seals on a Subaru?
The later brown colored seals are more resilient. The smart time to replace the front cam seals is when the timing belt it is changed, since much of the labor involved in replacing these oil seals involves the R&R (removal&reinstallation) of the timing belt. On the SOHC (single overhead cam) engines, there are two if these front camshaft oil seals.
Where is the oil cap on a Subaru EJ22T?
Also, EJ22 engines have a cam cap at the RH (right-hand) side rear of the engine. This cap also has an o-ring that can leak oil. (On SUBARU EJ22T (turbocharged) engines, the turbo oil return goes into this area).
