it might, but the can was not catching everything I don't think.. plenum and IH had more oil then I thought when I pulled it apart..
Searched a bunch of parts stores today, nobody had the 550-011 I needed, so I used the 550-013 and ground them smaller on the grinder.. added the holes and they worked good.. hoping to start the reinstall later tonight.
