Sorry to hear about your loss.
When I installed my aos I also had a leak at the turbo coolant pipe. Ended changing the provided clamp for a worm clamp from hardware store.

Thanks, my leak was actually the coolant return line to the head, probably the hardest one to reach when it's hot.

Just found this. My belated condolences. I have a 2006 Subaru sti with a coolant leak. This just happened and I had the car towed home. Now to find the leak.

[@DIYEVERYTHING]

I was lucky that it was just a loose clamp at the turbo.

[@PeterHernandez-lg2eh]

Today did a coolant leak pressure check . Koyorad radiator cap is 1.3 bars which is about 18 psi. Dropping to 15 psi unable to find leak will try again tomorrow.

[@DIYEVERYTHING]

Are you finding coolant under the car? If not, you may be looking at a bad head gasket.

[@PeterHernandez-lg2eh]

Did compression and leakdown test all good within specs. May be the turbo coolant lines. I 'll find it eventually. Much thanks for your input

[@PeterHernandez-lg2eh]

No coolant under car just coolant vapor when driving car hard on a 95 degree day with back to back traffic. 1st time this happened

I experiment less leaks whit full sintetic ACEA C3 standard, 5w40, in my jdm ej20g, forester stb.

That's good to hear. These leaks were simply from loose clamps, and I have not had an issue since.
