SOURCE: 86 audi 4000s - engine oil is oozing out of the oil filt. housing

is the filter tight? not clear about the Junction you are referring to. The filter screws directly into the engine block.

SOURCE: Need torque specs for oil pan gasket

There likely is a spec for oil pan but unless you are a finatic, you really don't need to know what it is. Simple rule: Don't crank down ******* any fastener. If corners near crank ends have larger fasteners, you can tighten them a bit more than on siderails. Before tightening anything, install all bolts finger tight, to ensure that they are not cross threaded. To avoid warping pan, tighten from the center of the pan, working towards both ends, alternating from side to side as you go. When you are finished, go over it again, using the same amount of force on each bolt. As I said, end bolts can if larger in diameter, be tightened more but be careful not to tighten so much that you will either split or push the gasket out the sides.. Anywhere two gasket ends **** together, I recommend using a sensor -safe dab of silicone. An oil pan is not under any mechanical stress or pressure. I have used this method for many years and NEVER had one leak. If you really need #s, small fasteners get about 12-15in lbs, larger ones about 20.

SOURCE: Need to remove oil filter housing - oil leaking

This is not an easy repair in your driveway, but can be done. 1st thing, have you checked to see if the oil filter is the issue or is it the drain plug? If its the oil filter housing gasket, you will need to remove the filter. The housing is held in place by the threaded bolt assy that the filter screws onto. You will need to remove that bolt, remove the coolant hoses. Clean the engine block surfaces, for the new gasket to mate to, clean the cooling housing surfaces, install the bolt through the housing, and install the gasket onto it. Then install the bolt/housing into the block and tighten the bolt. Install the coolant hoses, oil filter. Fill the cooling system with the coolant that you removed. Fill the engine with oil, start and check for leaks.

SOURCE: what kind of oil for 94 lincoln mark 8

I would 5w-30 non-synthetic, high mileage formula. Full synthetic will leak through old engine gaskets easier and the high mileage formula has the conditioner additive for the older gaskets.
Personally, I use Valvoline Maxlife in my car because it has over 100,000 miles on it. Works great.
