This is quite simple. The push rod tube is pressed into the cylinder on all 1970-1995 Airhead Boxers. Always give them a little tap after at the collar after you have rebuilt your top end. Push rod seals and the sealing area should never ever have any sealant or oil when the are being installed. As the rubber dries up and shrinks you will need to do this again. I have also had success when they weep cleaning the area with brake clean very well and tapping them in.
