Hello 240 people.
I have the B20 engine from my dads 75 240. the exhaust manifold has 4 little tubes running from it for emmisions.
My question is, would it be a bad thing to remove these little tubes and weld the holes closed? I ask because I hate to modify something that might have value to someone.
Having just sold a double pipe outlet manifold on Ebay I see they are very desirable. Any input is appreciated
thanks wilbur

How are these tubes attached? Are they welded in, screwed in, or what?

They are like litle pipe fittings that are threaded into the manifold and they are not comming out as they are welded in place by time and heat.
I will just have to cut them off flush. WILBUR

If they won't come out, cut them and then weld or braze the tubes shut.

The one I have has plugs screwed in the holes. That might be a good option
rather than welding, which MAY crack the manifold.

Try the question in the 140 forum. B20s were found in the 140 series but only in the '75-240 (after that it was B21s and B23s).
