TR4/4A Pushrod tube leaks?

After the motor has run for awhile I see evidence of oil in the area around the pushrod tubes. I don't think it's the valve cover gasket. Is it common for these engines to leak at the tubes? I see in the Moss diagram that they say to "swage the tube ends and seal with Blue Locktite". I wonder if the last person who did head work forgot to do this. Someone educate me on "swaging" and I assume this is done when the head is off and being reassembled? Is there a sealer that can fix this properly without pulling the head?

Karl,
my old TRs leaked oil around the pushrod tubes and I used a brass plumb bob I had to help flare or swage the ends and it slowed the leak. If locktite is called for I would use green since it's made for assembled fasteners and it wicks really well.
Good luck and let us know how it works.

I have had this problem with my TR3 for years and have never found a way to do it without pulling the head. If anyone out there knows the secret, I would be interested too.
