Unfortunately you have been given the causes for the code
take it to accredited service centers with experience on your make of vehicle and get quotes to fix
try to stay from the local garage as they can get expensive with getting it fixrd

P0442 I got the check engine light in my GMC savana 2008 I get this code P0442 it said. a small leak in detected can someone please help me with this problem I reset the code 2 times already the first time...

The P0442 code is for a small leak in the pressurized emission system. It can be caused from something as simple as not tightening the fuel cap all of the way after fueling, or a leaky seal at the gas cap, or a leaky o-ring around a number of sensors and fittings in the emission system. If you are sure that you are tightening the fuel cap all of the way, and have already replaced the fuel cap and see no nicks on the seal on the fuel cap or fuel neck, you might need to have the vehicle hooked up to a smoke machine to try and find where the leak is coming from.

My check engine light is on so I ran a scan with my personal car code reader & got code p0496. I called chevrolet & they told me its p0442. Which is correct?

p0496 is evap emission is high purge flow fault, p0442 is emission control system( small leak) the meaning is about the same. check for a bad gas cap first. sometimes this will set a check engine light. loosen cap and see if this is the problem. if it is. usually if you turn cap only a little the light will go out. but if bad enough just change cap.
