Flak280z Posted February 22 Share Posted February 22 Have an n42 block without a crankcase fitting on it. What are the options to replace this besides dropping $100 on one on ebay? Using search, I can only find one picture where someone on here replaced it with an AN fitting, but no sizing. Is it hard to remove one from an old block?

A to Z Posted February 23 Share Posted February 23 I removed the pipe from a block with a pipe wrench. Put the wrench on close to the block so as to not crimp the tubing, Strike the handle of the pipe wrench with a hammer, then push and use a pulling motion as you push it around, it will eventually come out. When re-installing put a piece of wood over the front of the pipe and use a hammer. 1 Quote Link to comment Share on other sites More sharing options...
A to Z Posted February 23 Share Posted February 23 once I got it out, it had some deep teeth marks, I had to take a file and smooth it back up. Painted it and then installed as I mentioned. It had been in there for 50 years, it was "permanently seated" basically. Quote Link to comment Share on other sites More sharing options...
jeffer949 Posted 8 hours ago Share Posted 8 hours ago Its just some steel tubing/piping. if your needing to replace one. measure the whole and add a few thousandths and find a pipe the right size to shove it in there. A metal lathe would help to get a perfect size but you can do sufficient job with a flat file. Quote Link to comment Share on other sites More sharing options...
