Workinprogress Posted November 3, 2005 Share Posted November 3, 2005 Hello all, I'm prepping my block for a rebuild, I'm about to remove the front and rear oil galley plugs to ensure the oil passages get very clean. Where can I get plugs that I can put in? (I know I have to tap the block) Are they just standard npt plugs or even set screw types? I think I'm just looking for flush mount plugs right? I'm using the "how to modify your L6 engine" book along with how to rebuild books. Thanks, Quote Link to comment Share on other sites More sharing options...
JMortensen Posted November 3, 2005 Share Posted November 3, 2005 Just use regular old pipe plugs. I think I used 3/8" on the block and 1/8" on the crank. I had my machinist tap the crank and he broke 4 taps in it. Hard steel... Quote Link to comment Share on other sites More sharing options...
Workinprogress Posted November 3, 2005 Author Share Posted November 3, 2005 I have no problem tapping the block but was thinking twice and thrice about attempting to run a tap in the crank. Thanks, Quote Link to comment Share on other sites More sharing options...

Your machinest didnt have the slightest clue what he was doing obviosly. The crans are not hard on the counter weights. I just tapped on last week, with zero problems.

JMortensen Posted November 3, 2005 Share Posted November 3, 2005 Well he's only been in business for 20 something years. Maybe you should go down there and show him which one is his *** and which is the hole in the ground... Quote Link to comment Share on other sites More sharing options...
1 fast z Posted November 3, 2005 Share Posted November 3, 2005 Well, Time doesnt make a difference. I know LOTS of 30 year experience machinest, and they dont know carbide from high speed. Im just saying, if YOUR machinest breaks 4 TAPS in a block, something isnt right. But what the hay, what do I know, Ive only been a machinest for about 12 years, and Im only 21. Wait, can that be????? Quote Link to comment Share on other sites More sharing options...
