Default TD04 Oil & Coolant Line Questions

Removed & reinstalled TD04 yesterday...

1. The oil return line hose: The bottom of the hose is clamped to lower hard line, but the upper end of the hose is just slipped onto the turbo hard line--that upper clamp is tough to get too! Is this ok, or will it pop/slip/blow off, without the clamp, up top?

2. I'm finding a slow drip/seep of coolant, from somewhere around the coolant lines attachment. I used new Autozone copper brake washers, which are identical in OD and thickness to the OEM; their ID was a smidge small, and took some dremeling to fit over the bolts. How much torque do these bolts take? I've gone back in on them several times with a 17mm box end, and they seem to keep giving a slight slip...maybe I'm still compressing the coppers? ...don't wanna crush the fittings there!

Thanks in advance!

Don't need the upper clamp. I've not used one for over three years, on three different Subarus.

When I change my turbo found it easier to clamp it from under the car.Jack up the front and use needle nose pillars to get in the tight space.It's still a PITA but I got it.

the lower hose coming from lower portion of turbo could be the problem.
but the top hose that comes from coolant tank also could why.

please double check that the clamps are past the rolled bead on water
coolant lines.

Thanks needles & turbo2ner!

Jax, I've to the hoses/coolant hardlines good...all inserted to proper depth, clamped fine, and no sign of leakage from them...it's coming from the metal fitting, attached to the CHRA.

Latest Info: I've finally found some numbers on coolant line torque, looks like 22-24 ft/lbs is the target. I'm sure I initially did NOT get anywhere near that, with my 17mm box end. I've gone back to them 5-6 times, giving each a snug up, and the leaking has ceased and coolant level is stable. :-)
