ka24de burning smells when high reving

[Phan]

hello, well heres my case, everytime i get on the freeway i would rev between 6-7 rpm when i get to 60-70mph my interior would smells "like" burning oil then it would go away when i say at 70.

my car doesn't overheat, i just change my motor oil (10w 40 full syntectic), change my transmission oil, fuel filter, air filter.

any input would be much appreciated.

hmmmm...could be an exhaust leak that is getting in your car threw the shift boot area

also i think nissan spec is 10w30

it could be the output shaft seal slinging oil off the driveshaft onto the exhaust or it could be the gromit that goes on the transmission where the stickshifter goes in, sometimes when thay are ripped thay gurgle oil up out of them at high rpms

Is there smoke coming out of your exhaust? if its blue your ready for some new rings, or a rebuild
