In preparation for an engine rebuild, I wanted to get myself up to speed on drilling/tapping the oil galley plugs.
Search revealed conflicting information about whether all should be removed and tapped or just the five big ones. What's the current school of thought on this? Also, what size plugs and drill/tap will I need. Thanks! http://www.914world.com/bbs2/index.php?sho...=103988&hl= |

I bought a box of 100 steel hex hed plugs from Grainger. It was like $20.
Harbor Freight has a $12 tap kit which I bought 2 of. Grind down the lead of 1 tap. Use the full tap to start the threads then chase with the ground down tap. Cut a little check the depth of the plug. Repeat until the plugs are just slightly proud of the case. Make sure you clean the galleys really well! |
