The first DIY doesn't mention disconnecting the battery's positive terminal, but the second DIY makes a big point about it. Better safe than sorry.

Oil Filter Housing Leak Repair

Thanks James,
People need to know that fixing the O.F. Housing Rubber Gasket is only one issue.
Another separate issue is the 2 Aluminum Plugs on the back side of the O.F. Housing can leak too. Here is the thread on it:

Anyone has a used (Leaking Recessed Plugs is fine) M52 Oil Filter Housing laying around so I can use as a guinea pig? I will return it in repaired condition (if the guinea pig is still alive LOL)
Here is what I am getting at, for those familiar with NPT (National Pipe Thread Tapered Thread) concept, it is basically Tapered Thread for good sealing.
The 3/4" Blue Anodized NPT Plug I just received has the standard NPT dimensions:
- Inner Groove: 24.80 mm
- Outer Thread Tips: 26.67 mm
Therefore, on the O.F. Housing Side, the bore size must be around or less than < 24-25 mm, this way I have room to tap the threads.
Again, I NEED A GUINEA PIG please!
cnn,
I saw that thread and your possible solution. Thanks for adding that.
I just posted the Oil Filter Housing OVERHAUL: from O.F. Housing Seal to the Repair of leaking "Freeze Plugs":

is this the same procedure for the v8?
The reason is the alternator wire is still "hot" until disconnected at the battery. Good luck on the oil filter housing seal. Did mine last weekend. Be sure and follow the tip to write down where the six housing bolts go. They are of different lengths. And don't mistake the idler pulley for the tensioner. I did at first. A PITA, but do-able.
