More like 7 or 8. I'll have to look at my case, but there are 2 or 3 on the flywheel end, 1 on the passenger side, 2 on the front, and 2 to the oil cooler. I'm not sure if people replace all of them with threaded plugs or not, but mine are.

You can do all of them, but I think most people do the 5 larger ones -- the ones that are most susceptible to blowing (the smaller ones apparently not).
Here's a good reference which ones:

There are 11 in total.
I know in my situation, out of the two cases I have, at least one of the small plugs was loose and showed evidence of weeping. It took very little force to pull that one out vs. the majority of the others.
Photos of many of them are at this thread pages 3 & 4:

Yes, only the big 5, I've never seen any of the small plugs leak, just the big ones.
I had a customer who tried to do the others, he drilled into the totally wrong area of the relief and ruined a good 2.0 case.

Thank you every one.
now isn't there an updated oil pressure release valve?

Good job
The hole on the left first pic you have to make sure the plug sits close to flush or it will hit the flywheel, At the same time you need to take care not drill in too far, but it's OK if the threads (not the plug!) reach the first small galley. The plug can only sit about an 1/8" proud.

Didn't realize you were drilling and tapping on an assembled engine.
Please clean those galleys out very carfully to ensure no swarf has entered the galley. Maybe with a long car detailing Q-tips with oil on the cotton end to help "grab" any debris?

BTW the 2nd pic the right (top) hole is where you would install a 90 degree street elbow if doing a full flow system.
For race or upper tier performance cars usually for running a front cooler. You would plug the pump and use a T1 full flow cover, remote filter, etc.

I've done this many times, grease the tap and clean it often. I always warn that it could go bad, but I've never lost an engine. Besides the repair is often for a plug leak or blow out, so either way the engine is fuched.
Cleaning the tap is key, never counted but I likely clean and re-grease 10 times per hole.

Flywheel 1/2 side plug still looks too proud and may touch the flywheel.

Time to fix this is now.
Stick the flywheel on now, don't worry about a seal yet, check the plug and it will be hitting
You can grind a bit off the two ends of the plug, but only so much on the hex drive end.
The NPT thread is a taper thread so you will have to drill and tap the hole deeper, so the plug will sit in deeper. This is the hole that makes me prefer steel plugs, because steel has the strongest hex drive.
I don't like Teflon sealant (on plugs) as you could over torque and crack the bung, never seen this with the T4 but I've seen this with T1 cases. I use green locktite.

What tap are you using? Is this a standard pipe tap or is this a shorter version of one

I did take some off the plug , I was touching the fly wheel, ground it off
