OK well i did a search and couldnt find a postive answer. I have read in a couple of posts that some people are having difficulty drilling the oil pan the right size. now I have the HAHN Stage 2 Kit for my 2002 Eco Cav. The manual says i need to make a 3/8NPT tap. i am just double checkin but is htis correct before i drill? cause i have read that some people are using a 1/2NPT tap. so any help would be awesome. thanks

I fell obligated to help you

The TAP is 3/8NPT. That IS NOT the drill size. DO NOT drill a 3/8in hole. Go buy a 3/8NPT tap and get the recommended drill bit for it at the same time.
