I have a Dohc 94 and I belive that my cam and or followers are making a clicking rattling noise at startup for about 10 - 15 seconds and a substantialy less amount of noise during some driving conditions I was running 15w 40 which solved these problems for a while but when they returned i swithced back to a 10w 30 at my last oil change because i havent been driving her as hard and i was hoping to get a little better gas millage i know that it is a cardinal sin to do that but im just trying to solve this problem cheeply and figured they werent getting enough oil, what are some other possibilities?

it's probably your VTCs making noise.
use a wix filter and a good 5w30 oil and you should be fine.
if that fails, just ground them out.

VTEC and VTCs are very different technologies.

it is a solenoid that changes the cam timing between 2 set points depending on an assortment of factors.
DO NOT TRY TO PLAY WITH IT. people have tried to tweak it on the dyno and there were 0 gains from playing with it. the factory has it dead on.
