when i first start my car it does not smoke until about 15 seconds then it starts to burn oil, if i let it keep idleing it gets worse, and when i give it some gas smoke just billows out of the tailpipe and ITS NOT COOANT IT IS OIL, anybody have any ideas??someone told me i had a bent valve or a bad valve??

 

Most likley blown head gasket, do a leakdown test... drain oil and look for water in oil

 

could also be a blown/soon to be blowon piston ring

 

Could be the valve seals, but since it's at idle I'm guessing it is probably the head gasket.
