250 Inline Air Injection Tubes



I have my engine out and to clean up(paint) and fix leaks. I briefly caught a glimpse of something moving in one of the intake ports. I stuck my finger in and felt these little tubes flopping around.

I went ahead and pulled the plugs out and took the little tubes out.

Were they just lazy when they put the plugs in and didn't pull them out? Any pro's or con's to having them out?

Totally lazy. If not incompetant. Anyway just pull the tubes and seal the ports.
The A.I.R. system was bogus from day one.

Re: 250 Inline Air Injection Tubes

Mine were still in too They were carboned up and stuck tight but a small pry bar levered most of them out easy. The 2 forward ones were stuck and wanted to fold up and kink. I had to sharpen a bolt almost like a pencil point and thread in from the top half a turn and they broke loose and free spun. Then pried out easy after that.
