Could this have cause the vtec not to engage anymore because the vtec was working properly and a couple of days ago i hit a rock that dented my oil pan right next to the oil drain bolt and now i dont hear vtec anymore.. Or could it be electrical problems before the rock accident, vtec wants to work it will work and sometime it doesnt..

 

Maybe the dent is causing low oil pressure. When there is low oil pressure, VTEC is not going to engage. If there is not enough oil, VTEC will not engage. Do you have any CELs or any other lights come on? Try removing the oil pan, bash the dented part out and check if that helps. It's probably the problem.

 

If oil doesnt travel up the oil pump then yes VTEC wont work. A dented oil pan could be the cause.

 

I'll try taking the oil pan out and bashing back out does any one know if i should replace the gasket around the oil pan..

 

if the oil preasure light is not on then i would say that the dent is not the problem, most likely an electrical problem, or you may just be low on oil

 

no the oil pressure light is not on and i do have enough oil in my car and maybe if its an electrical problems than does anyone know what part of that electrical problem might be. check wire to ecu is ok and all plugs are plugs. I do have check engine light intition misfire and that only makes me crank my car for a couple of seconds than my car starts. any anwers will help...

 

yes you should replace the gasket and use hondabond, and criss cross the bolts when putting it back on

 

What kind of car do you have and what motor?
