What needs to be done?
Hello,
I have a 2002 Nissan Maxima, It is Consuming Oil and the Engine is Rattling more than before. My car is also giving lower MPG than it's supposed to.
Any reason why all this?
1-I like my car, it's still fast and strong but, Is it worth fixing?
2-What exactly needs to be fix?
3-What specific parts are really needed?
P.S. : My car has new valve covers, new filters, new spark plugs, 3 new rear coils, Well maintained, etc...
Thank you

Drive it till the engine dies. Put a new engine in and keep driving it.
A good portion of the early VQ35's burned oil. Mine burned oil since I purchase it with 109k.
About 3k before the engine gave out in mine I started losing mpg's and consuming more oil than "normal". It went from a quart every 800 miles to every 400 miles.
Mine made it to 207k. I think it's worth fixing if it's been a good car otherwise. But that's just me.

These are extremely common problem's for the VQ engine. Just browsing through this forum will give you a ton of information and most importantly, correct information.
I also have a 02 with 156k burning tons of oil, original owner was my father in-law who bought it new. He's very meticulous with his maintenance as well. The problems that develop with these motors is not from lack of maintenance so you've done nothing wrong.
But Qman is right, keep the oil topped off and drive it. You can install a catch can to help filter some oil passing through the pcv system, but it will still burn oil. When it unfortunately is time to deal with it, you can take your chances on a used motor. Which will probably have the same issues, or rebuild.
I have tons of parts for when that day comes and am researching a reputable VQ rebuilder in my area. Love my MAX and it will live on.

Get Something Going
Search oil catch can. It pretty much collects oil that would otherwise be put back in your engine via intake manifold to be re-burned. Can help with mpg and keeping your internal engine parts cleaner. But is something that will need to be emptied often depending on the capacity of the can you install.

Just to chime in here but oil consumption and lower gas mileage could be bad/worn piston rings or bad cylinder walls. Basically you would need to rebuild the motor if that is the case. If the rattle is in the chain and you want to help extend the life of the motor, the tensioner/guides is a good thing to do. It may actually help get better gas mileage as the chain will lose some of its "freeplay" that it has because of the extra slop.
