2002 Nissan Xterra Q&A
2002 Nissan Xterra Question: Engine burning oil
I have a 2002 Xterra supercharged 3.3lt. V6. we have no engine lights coming on , no oil lights coming on nothing!! We just had the right exhaust manifold replaced as it had a crack in it. But the reason for talking it there was for the ticking or nocking that we were hearing. We were told that the computer diagnostic check did not spit out any codes what so ever, and that they do not know where to start to look or even what might have caused this to happen. Nissan dealership said we should just scrap this one and buy another, are you kidding me? If anyone has any suggestions it is now at the 3rd mechanic -I will never go back to Nissan especially since they can't even fix their own vehicles. Ours has 157000 kms . - mooyak
There are many reasons could be burning oil that are not related to cracked exhaust. Piston rings, valve guides and seals, problems at the supercharger bearings.

Sometimes a great shop can perform magic when greatly motivated. If you like the car there is no reason to get rid of it. By the way, how do you know is burning oil? Let the shop know what you know and don't hold back. Sometimes one thing you say can lead a good tech to a quick answer for you. - raiderron
I'm no professional but that sounds like a rod bearing to me. Especially with the miles that high. Even well maintained engines will get wear and tear to piston rings valve guides etc causing a drop in compression and oil consumption. - johnnymonte
When started it immediately goes to high. Oil reading good, new filter and oil.
I'm having a intermittent problem with my xterra occassionally shifting into first gear. It's odd I'll drive and sometimes it will not shift into first, I'll cut the car off and it will correct the...
