My oil pan leaks. Can I put an additive in the oil to stop this leak?
No- don't put anything in your engine but oil- try tightening the pan- if you need to, just replace the oil pan gasket- don't cheap out, not with that car- don't add to your problems-
Second opinion. No No No, just like jam says. You will have a chemical goop circulation through your engine looking for holes to plug. The first ones are often the small holes in crank bearings to let oil between bearing and crank journal --This is not a Jag but same thing. If even one of these gets plugged it will spin a bearing and that = $$$$
Third Opinion. Not only NO , but hell NO! The problem needs to be properly repaired.
