stripped oil pan bolts

ok so I have an oil leak that i have been trying to hunt down for a while. all the usual suspects OFHG, CCV, dipstick tube oring, vanos line all replaced, now leak is now much smaller. so then I use some long cotton swabs to swab up through the window on the transmission bell to see if the main seal is the culprit, its dry. so I really have it narrowed down to oil pan. I break out the in/lbs tourque wrench and just want to make sure everything is tight before I go crazy to replace gasket on an xi which should be a nightmare (I might as well just swap in the 330 while im at it.) 3 bolts on the pan are already stripped :censor::censor: not sure if the 200+k just did it to them or the PO or PO mechanic, but it seams like every bolt i touch on this car is already stripped.



anyways what are my options at this point? not even sure how the job on an xi goes pull axels, diff, subframe and oil pan then use timesert to retap the holes?

or should i just let it drip and top it off, it only drips 1 liter every few months.
