Oil filter housing

Looks like you have either quick Disconnect fittings or flared fittings. If you have quick disconnects, you have to remove them only one way. Pull plastic cap back down the line about 2 inches.

Using a bent tip screw driver, pull on one of the ends of the retaining ring to rotate the ring around the fitting until it is out of position and can be removed.
Pull the coller line straight out of the fitting.

To install:
After inserting cooler line in fitting, hook one end of the ring in one of the slots of the fitting. Rotate the ring around the fitting until ring is positioned with all 3 ears through the slots.

Do Not install the ring by pressing it down over the fitting.
Always use new rings and caps when installing fittings.

Remove the bolts to the block and the oil filter adapter will come of so you can replace the gasket. Check out the diagrams (Below)

Please let us know if you need anything else to get the problem fixed.

IF your lines just have metal flared fittings, then dont worry about the quick disconnect ones.
Here is how you replace the Oil filter housing.

REMOVAL
Remove the oil filter.
Remove the oil cooler lines.
Remove the bolts.
Remove the oil filter adapter.
Remove the gasket and seal.

INSTALLATION
Install the oil filter adapter gasket.
Install the oil filter adapter.
Install the bolts.
Tighten the bolts to 20 Nm (18 ft. Lbs.).
Install the oil cooler lines.
Install the oil filter.
Install the engine oil, as needed.

When you remove the cooler lines, you will just need to unscrew the flared nuts. On the housing itself you will probably find that the cooler lines have removable fittings that have o-rings under them. After you have the housing out, you can remove the fittings and replace the o-rings. There is a gasket above the housing that needs to be replaced. If this is where you have a leak, then I would replace all of the seals, and be sure to inspect the fittings and housing for cracks.

Well, most auto parts stores will have o-ring kits where you match up the o-rings from a kit. However, if they are specific seals that cant be matched up, you will have to use the dealers seals.

I found a good photo of the fittings, but if you remove the two lines, and then remove the attach bolts, when you have the housing in hand, you will see that the fittings just screw right out.
