Could be oil smoke, it's white with a slight blue tint. If the engine was not properly maintained or abused, the piston rings can wear. Worn piston rings might allow oil from the crankcase to pass into the combustion chamber; there, it will be burned and pushed out the exhaust.

Hi Merlin I THINK this is your fuse panel and location for the washer pump fuse. (See link below) Hope this helps you out. -Steve 2003 nissan altima fuse diagram Google Search

What did you change on the bottom half?

Should know the code for your radio and enter it,check the owners manual it may be written somewhere in there if not you have go to dealer

you need to buy or rent spring decompressors before you attempt to work on them. It is very dangererous otherwise. once tool is in place and spring decompressed to a 1/4 in gap on either top or bottom spring plate. in trunk remove carpet or felt cover.usually plastic snaps or screws into from the lining. from the wheel well there should be a plastic cap standard screw driver should be able to pop it open. this is a bolt to the shock. once removed the suspesion should drop and the spring is removable. but if the gas in shock wont go down then the bottom bolts need to removed, then use jack to decompress shock off mount and it should come out

it sounds like trouble with the torque converter / check transmission oil levels or take it to transmission shop for check up

I assume that you have a 6cyl engine, noise came from both worned secondary timing chain tenssioner shoes, just replace those two and while you have them all apart, also replace main tenssioner and guide, then all noises will go away. Good luck!

Everything blocking the timing chain cover needs to be removed. THEN REMOVE COVER AND REMOVE OLD CHAIN making sure your cam and crank marks align. install new chain

Cracked engine block.

You will either find the code in your car's manual or you can contact a Dealer for the code. The radio disables when it is off-battery to prevent thieves from stealing it and being able to use it.

Either the throttle body butterfly is not closing all the way (dirty) or the idle air motor is dirty and sticking.
