is there anything tricky to fixing leaking vtec spool valves? I read that there are 2 different gaskets to replace..but I was wondering if there is anything tricky to working on these components. Like, is there something that needs to re-engage when putting it bak onto the head..or something along those lines. I have no clue what is inside the darn thing. I'm a reasonably skilled shade tree mechanic and would like to save a few buck and have a little fun working on my new purchase.
