Question about 2003 Nissan Altima

1 Answer

Clunking sound upon starting and white smoke from

My mom's Altima makes a loud clunking sound upon starting in the morning, then it subsides. She doesn't hear this sound in the afternoon or evening when starting her car. White smoke comes from the exhaust upon acceleration throughout the day. Her mechanic has told her she needs an engine rebuild costing $1,700, however my research has pointed toward a bad gasket. Is she being taken?
thanks...

Don't rebuild that engine. Replace the head gasket. machining the head is not necessary. Clean both surfaces with fine emery cloth.

I have a Z24 Cavalier and theres white smoke coming out the exhaust and timing chain makes a lil rattle noise when I first start it in the morning and tends to stall until it reaches the temp of 165ish...


So if it's not consuming oil and you are SURE to fill the radiator to PROVE it's not burning coolant ... then the other suspects are head gasket and .... A puff of smoke upon start-up could be caused by valve guide seals allowing some oil to leak down into the cylinders while the car is parked and not running. This would be pretty common on a nine year old car and should not, in most cases, be cause for concern - See more at: http://community.cartalk.com/discussion/2280708/white-smoke-from-exhaust-upon-cold-start#sthash.05fuptIx.dpuf

If it's blue-white then What you might be seeing is oil burn-off from leaking valve guide seals. The next time you have the oil/filter changed, have a high mileage oil installed. - See more at: http://community.cartalk.com/discussion/2294478/white-smoke-coming-from-the-tail-pipe#sthash.jVo0zDhw.dpuf

Its probably back-firing in the intake - which means it is firing early or the fuel mixture is very lean.
This engine uses a distributor cap and rotor, so I would start there and make sure the cylinders are firing correctly.
If the ignition checks out ok, it could be a problem with the cam timing.

2007 Nissan Altima - smoke from tailpipe


It sounds normal white smoke comes from moisture in the air as it's burned and the air temprature is different. it creates steam they gray smoke is a little harder to decide what it is, normally gray smoke is related to oil burning and black is over fuel, depending on how many miles it has on it it could have bad valve guide seals but would not worry about it.

My 1996 nissan sounds "clogged up" Once and awhile white smoke comes out of the muffler, but not consistent. When I first start it in the morning, it stalls about 3 to 4 times and then seems fine. ...


Sounds like water in the fuel system. White is water in the cylinders. Check the fuel filter and let me know. If its not this then I will advise further. Cheers
