I bought the after market 17mm oil filter bolt shown in the picture below. Comparing it to the stock bolt I noticed the stock bolt's oil flow holes are beveled for better oil flow and the after market one's holes are not. My questions are:
1. Does it matter?
2. If it does matter and I get out my dremel to port the little holes, should I remove the check valve mechanism first and
3. If I remove the check valve mechanism by punching out the set pin, is it difficult to get it back together?
As always, thanks a bunch,
