I found it really difficult to get to these when removing the engine. I’ve now noticed a very slight weep from one of them.

So I’d like to get a crows foot or some tool on there to properly torque them. What size are they and what torque?

Your attachment didn't work for me, but from manual... Section KJ

LH Front Oil Cooler (Feed) Hose

Refitment:
Refit is the reverse order to removal.

1. Ensure the hose route is unhindered, cannot rub on
other components and is free of any kinks allowing the
oil to flow freely (see Fig 2).

Note, the hose should be routed so that is postioned
in between the washer reservoir hose and crash structure
and to the left (outwards) of the transfer hose at
the area where it passes near the transfer hose 'P' clip
(see Fig 2).

Position the hose connection at the sill pipe so that it can follow the heater feed pipe routing without any
strain being placed on the hose once it is secured with new cable ties to the heater pipe. (See Fig 1).

2. Tighten the hose at the oil cooler and sill pipe connections to 40Nm, a 30mm crowsfoot adaptor is required
to carry out this operation. (Also see note 1 of removal step 3 for tightening instructions). SEE BELOW

3. Fit new tie wraps and re-check hose routing.

4. Ensure the engine oil is topped up to the maximum mark on the dipstick.

5. Run the engine until hot, the sandwich plate will open at 72°C (162° F)

6. When the sandwich plate is open, the oil cooler pipes will be hot to the touch and the coolers will feel
warm.

7. Once the sandwich plate has opened, turn off the engine, leave for 3 minutes allowing time for oil to drain
back down to the bottom of the engine and re-check the engine oil level and adjust as necessary.

Note1 of removal: To avoid placing unnecessary strain and movement
on the sill pipe and oil cooler , hold there union
nuts with an open ended spanner whilst using another
spanner or crows foot adaptor on the hose connector
unions when loosening or tightening.

I cannot see your attachment so don't know if you are taking at front coolers or at engine block thermostat. Most of these fittings are a BSP (British Pipe Standard).

Is the weep at the threaded joint or at the compression fitting? was recall performed?

Sandwich plate appears to be the same...

Tighten the hose connections at the sandwich plate and sill
pipe to 40Nm, (a 30mm crowsfoot adaptor is required to carryout this operation).

Note: It may be necessary rotate the sandwich plate very slightly
from its original position to ensure that the oil hose route and
orientation are correct. If this is required then carry out the following
steps as also shown in Fig 13:

Note: In the event that the adaptor tubes are disturbed it is
recommended that the bonded sealing washers positioned between
the tubes and sandwich plate housing face are renewed.
Also a thin smear of engine oil should be applied to the rubber
seal section of the washers to prevent tearing damage occurring
whilst tightening the adaptors to the sandwich plate.

Didnt know there was a recall. Mines MY13 manual S.

It was bone dry when I took them off now looks like a drip around the fitting.

They did come loose and I did have trouble aligning things when tightening them up. So may have damaged them.

Do you know what size those are and where I could find some?
