Oil leak from the front of the engine

So, bad sight this morning. I was about to get in my car to head to work this morning and noticed some drops of oil at the front of the car.

Here's what it looks like.

This was taken by sticking my phone up in right in front of the radiator, camera pointed towards the back of the car. You can see the oil pan has some oil spray on it - it's apparently been slow leaking for a bit.

This is looking up, you can see the crosspipe of the exhaust at the bottom of the image.

The timing belt cover has oil on it as well, on the passenger side and middle.

Driver's side of the timing belt cover is dry as a bone.

So, is this definitely a crank seal or cam seal?

I got the timing belt done about 6 years/60,000 miles ago. Seals were not done - they looked good at the time, apparently. Should I just replace the seals? Or do the belt/idlers/water pump as well since I'm in there about 30k miles early?

Anything else it could be before I resign myself to this big job?

Re: Oil leak from the front of the engine

It’s your oil pump seal leaking, you’ll have to remove the timing belt to get to it. My Outback had the same exact leak, it got worse and worse till it forced me to have to fix it.

Re: Oil leak from the front of the engine

Shoot. What do you think about the t-belt? Should I do a whole kit replacement as well since I might find oil got on the belt itself? I understand a lot of people skip the water pump - maybe leave that as-is?

Unless you had the t belt replace recently treat this as an opportunity to do the t belt service and fix leaky seal(s). The parts aren't expensive.

Re: Oil leak from the front of the engine

The rubber on the timing belt is wrecked now. I would suggest not driving the car until it is fixed.

If you intend to keep the car, reseal the entire front of the motor - all 4 cam seals and the oil pump seal. New water pump and tensioners/bearings are recommended.

Not really recently, but it should still have a few years of life left had this not happened. Oh well.

Yeah, I've been seeing that the oil can damage the belt. I just ordered the Aisin timing belt kit - has all the idlers, water pump, tensioner, etc.

Also just talked with my local dealership for all the seals. Been a while since I had to work with the parts department - guy had no clue what a 9-2x was. Nothing new, just always disappointing that people that don't care about cars work in roles like that.  facepalm

Re: Oil leak from the front of the engine

I'm happy to report that I successfully changed all 4 cam seals, crank/oil pump seal, timing belt, all idlers/tensioner, and water pump.

It was a tough job, but nothing specifically gave me a ton of grief. One thing I found that I didn't like was that my water pump had been replaced without an OEM gasket - it was a gasket maker goop type material I had to clean off before replacing the pump.

Anyway, it's fixed and I'm back on the road.
