so after putting in the T28 which is NOT i repeat NOT a direct fit from the T25, with everything back in after the first start up it starts squirting out oil. so i check and its leaking between the block and oil line fitting from the turbo... turns out the threads in the block are stripped! im very frustrated right now, ive tried using some teflon tape to seal it up, i tried more washers, still nothing.
can someone help me please, some suggestions on what to do and if anyone else has had this problem let me know what you did to fix it. and yes i know most people will just say re tapp it, so thanks but that will be my last resort. please help.

This just happened to a buddy of mine. He ultimately had to put a helicoil in the block..and all is well.

here are 2 other threads of people with the same problems, i am sure there are others that can be found..

The size is M12x1.25. Drill bit size is 31/64. Just drill, tap, put in the coil and your back to new. But practice makes perfect so at least try it a couple of times on something else first. You can buy a helicoil kit from your local hardware store, auto store or even eBay. If you need any help along the way just post up your questions and someone will speak up. Good luck.
