broken oil pan bolts
The jap motor I bought seems to have a problem with the oil pan bolts. Since the pan it came with it was trashed I decided to swap it out and proceded to brake not one but 7 bolts! They broke along the drivers side front corner of the engine, for the most part they are evenly distributed along that corner meaning for every busted bolt there are a few healthy ones after it. I put on a fresh gasket and managed to remove 2 of the old bolts and put in bolts from the other motor so I'm down to 5 gaps. My question is even with carful torqing and RTV on both sides of the gasket am I still doomed to a bad oil leak.

What works best for me is to put a nut over the place where the broken stud is and using a welder build up material - welding the broken stud to the nut.
A TIG welder works best - but I've done it with even a flux core MIG welder.
If you break off the head while trying to remove the stud - reweld it and try again.
This beats the **** out of trying to drill and tap.

Another thing I just thought of, get a drift and a hammer and tap on the bolts with some reasonable force before you drill them out, this helps to break loose whatever is holding them in so tightly. Good Luck!
*edit* another thing lol, if you can find it around where you live, get a can of AeroKroil penetrating oil, its in an orange can with a black top and use that too, I have not found anything as effective as aerokroil in these situations. Its almost as awsome as seafoam lol.
