Here's the skinny on converting your non oil-filter GY6 to a filtered GY6.



Step 1 - Remove and diassemble engine



Step 2 - Remove oil pump from side case.



Step 3 - You will see a brass plug that is pressed into the front of the block to plug the outlet passage from the oil pump. Place case in machine vise and center on brass plug, drill for 1/8 pipe tap. You will need to completely drill through the plug into the oil passage.



Step 4 - Drill another hole exactly 1.550" from the centerline of your first hole on the left side of case as shown. Same drill size for 1/8 pipe tap.



Step 5 - Tap with 1/8 pipe tap. Be careful don't go too deep into the drilled holes. Plus the hole on the left doesn't have much meat.



Step 6 - You will have to fashion a plug to block the passage between the two holes you drilled. You'll see what I mean when you examine the case. The plug will be a odd shape. I machined mine from aluminum then pressed into passage. Next slop some JB weld to seal the passage permantly.



Step 7 - Using a sealing loctite screw your 1/8 pipe fitting into block. You can use a barb or -4 AN adapter, your preference. These fitting should not be taken out on a regular basis. The aluminum for the cases is soft and will strip quite easily. Do not over torque the fittings either.



Step 8 - Hook up your own remote filter and cooler as required.



Step 9 - I assume no responsibility for screwing up your case. If you're nervous about doing this pm me and I can do it for you for a small fee.



If in the future you plan to not run a cooler or filter you will need to hook the outlet into the inlet. Otherwise no oil to engine, engine go boom!!
