For people that do not know what they are doing be afraid, be very afraid. Not saying don't try it just be careful. I do all my own work on my cars, and can tear through anything with a wrench and i have still had some major problems. The famous water in the spark plug tubes happens all the time, especially when i had nologys on my teg, not to mention the time that the water blew my coil, which was 70 bucks and scared the living shit out of me (car would not start). Just wrap the distributor block well, and use an air compressor to blow out the plug holes, all the abs stuff and all that is really nothing to worry about, neither is the intake.
