If you are losing anti-freeze, and oil. That could be a sign. Look aqround the baase fo the headgasket. Usually you will be able to see where it is leaking if it is leaking. If possible get under the car as well and just look all over to see where it's leaking. That will give you a better idea to find if it truely is the head gasket. On a Integra, just looking at it, it does not seem to be that hard of a gasket, unlike the grand am quad 4 motors which is a 13hr job on the head gasket.

If you dont feel comfortable doing it yourself, nor any of your buddies i would not attempt it. Trying to save $300-400 by paying someone, and messing up timing and possibly bending a valve will cost you more in the end. The hardest part will be the timing belt. WHich really is not hard at all. I have a Clymer manual, pretty good. I have done 2 head gaskets on 2 turbo Talons, and one on a Civic.

I would pretty much reccomend bringing it to a shop. The only "specialty" tool that you will need will be a torque wrench. Air tool make it alot quicker with the "wizzer" we call it to remove the old gasket material.
