the other day my vtec was sounding good and really loud when it kicked in at like 5500 rpm, but now it doesnt seem to kick in anymore, i don't know what the problem is, anybody have an idea on what might be wrong with it,

 

checked oil?

 

oil give lifes 2 the moyor so im thinking thats the problem lets just hope u didnt do damage 2 the motor if its knocking or starting 2 eat oil reaklly quick or smoking alot then u gota serious problem

 

for some reason my oil was empty i just refueled it but still no vtec sound........

 

The solenoid could have crapped out. Check that.
