Question: valve cover replacement?

my 2002 Nissan Maxima (136k miles) is burning between a quart and a quart and a half of fuel every 1000 miles. The mechanic recommended getting the valve covers replaced to see if this fixes the problem. The issue is that this will cost at least $800 and he is not sure that this will fix the problem. Do you think I should get this done, and what are the chances that it will stop the oil burning?

I think you mean it uses oil, not fuel. And if the valve covers are leaking ALOT, it could be your oil consumption problem. But it would have to be a pretty big leak to use that much oil. And it would probably smell like burning oil when you drive it.

It could be the engine oil rings may be wearing and that would require an engine tear down to fix it.
