recently i noticed that my vtec engages,drops and kicks back in right away.

not every time i only heard it 3 times

the oil pressure is always at 70-80 doesnt fluctuate much
oil is halfway between marks
ive used 0w30 since it was first started

Have you taken it off to see if there is any shavings/gunk in there? What RPM's does it fluctuate, and is it consistent?

Test the vtec solenoid or pressure switch? could be taking a dump...

make sure oil pan is not dented in to where the oil pickup can not pick up enough oil.
