vtec solinoid is one of the easiest things to take out.
see if there're any oil leaking from there. it has a little gasket, that costs around $2 at the honda dealer.
if its leaking then change out that gasket.
i forgot how many bolts there were on the vtec solinoid.
but trust me its right there behind the distributor. i didn't have to remove anyother part to take it out.
