You just tap them back until they are fully seated. Best is to use a socket that is the same outer diameter as the seal but you can use a punch and work around the outer part of the seal but you have to be very very careful doing it that way. I also would not recommend and rtv. If you add too much rtv can actually get into the seal and cause a leak. I've seen it a hundred times before. A properly installed seal needs nothing extra to seal. I worked for mitsu for over 6years and am currently a small engine mechanic so I've seen alot of different applications. Also if your cam seals are leaking and your doing a timing belt change I would highly recommend replacing you crank seal. Its better to do it now then find out later you have to take everything apart again to fix the leak.

Completely agree, nicely done.

The most common way to get to the seals is by removing the timing belt. With the belt removed, remove the valve cover and use a 1/2" breaker bar with appropriate socket for the cam sprocket bolt and a large wrench on the hex portion of the camshaft (as shown in the attached picture) to break the bolt loose. You do want to lubricate the inner lip of the seal with engine oil for easier installation. For a 2G, follow this guide on the VFAQ to removing and reinstalling the timing belt: Timing Belt VFAQ

The other way of doing it was suggested and linked to (first post) in this thread: http://www.dsmtuners.com/forums/cylinder-head-short-block/381586-question-about-t-belt-when-pulling-head.html; it is not something I would try but it should work just as well.

thanx for all this great info and write up guys
i decided to just do it right and redo the timing belt while i was at it to not risk skipping a tooth. getting the seals in was easy.

and as for the crank seals its a new motor with 0 miles i put all new seals on it but i guess the one on the exhaust cam got messed up so i put another new one.

well 5 hours later i redid seals, timing, and belts (my first time doing timing chain in car) cranked her on and zero leaks
