2010 Legacy GT Limited

[Rkslegacy]

I recently purchased a 2010 Legacy gt with high mileage. What are some things I should look out for and replace? It does have an oil leak but don't know where from yet. What's a common place they leak oil from? TIA

Guessing the oil leak would be from the valve cover gaskets.

 

Make sure you change the coolant if not done recently, the 2010 GT did blow headgaskets, there was a bit of a list growing:

Check the control arm bushings too, they crack with age.

 

Also check the rubber T piece that the PCV valve is connected to, that was cracked on mine from age. Should probably just change that T hose and valve anyway by now.

How many miles is high mileage?

Car has 190k miles but the engine was replaced at 112k miles so the new one has 78k miles

The timing belt/water pump & coolant change likely was done with the replacement engine. The engine is probably due for spark plugs and fuel filter (every 60k miles) and I would change the transmission and rear differential fluid. While the spark plugs are being done, check the coil pack cooling fins to see if they are expanding from rust. When they start to expand, they fail short after.

I would guess that oil leak is the valve covers as mentioned above. If they are replaced, make sure to do the spark plug tube seals as well.
