Default 2001 4cyl camry smokes on startup

2001 camry 4cyl has 57000 miles. After being in the garage all night the car
blows smoke after the first startup in the morning. This occurs about every
third or forth start. At other times I don't see a thing. Oil consumption is
about one qt every 5000 miles. Oil and filter are changed every 5000 miles.
This started after 50000 miles.
Anybody else have a problem like this?

YES, I Do. With a 93 camry with 57k on it, a 94 camry with 161k on
it and a 99 camry with 65k on it. But (yes, the But) only if the car
is parked facing a slight downhill tilt in my driveway. If I park the
any of the cars facing uphill, no smoke. I'm at a loss for an
explanation since all 3 pass Ma state emissions testing for
inspection. Dan

The most likely culprit for both of your problems is worn valve guide
seals. This will result in a small puff of oil smoke when the car is
started, and the longer the car sits, the larger the puff, to a point.
Generally it goes by mileage, but age may be a factor too. Funny thing is,
none of MY cars started doing this until they had over 225,000 miles and
had been sitting parked for over a year! It will pass the MA emissions,
because you have to drive the car there, and the oil at the seals
dissipates. The small amount that collect from the time you park it until
the tester takes it is not enough for oil to pool in the cylinders. As for
uphil/downhill....??? I have been told this is fairly easy, but approx
$4-600 by an independant repair shop. Luckily, the two guys I rely on the
most have done them before, one of them having owned 5 Toyotas. BTW, he is
in Mass, so if you want I can probably hook you up. W.Mass, that is...

Nothing to worry about, and it is actualy good for the motor as it lubes
your cilinders free overnight and reduces Dry oil starting. Its Valve
guides. And has not affected my oil consumption or polution tests. I
burn 1/2 quart in 3000m So it is honestly good for your motor.

I'm no car expert but that sounds silly to me. If it was good for your
cylinders wouldn't it be designed into the system?

Its really the valve guide seals, They are rubber.
Try the high mileage type oils that swell the seals slightly.
Worked for me at 60,000mi. No smoke now at 190,000 mi.

No it isnt silly, Oil starvation, and alot of wear occurs on startup
befor the pump has circulated oil. Pre pressurising systems are
avalaible for race motors. Think about it, 2 strokes lube through the
gas immediatly, A minute drop of oil in cilinders vaporises and also
lubes. My car uses 1/2 - 1 quart in 4-5000m. It smokes a bit on startup
but has harmed nothing and probably helped the piston rings alot.

Before Catylitic converters made this wrong I knew a mechanic whose
commercial drivers would add a cup of oil to their gas. It was even sold
as " top oil" . They stated longer ring life was guarnteed. I would not
worry unless oil consumption goes up.

Please pardon my dissension. I don't believe it's good for your
cylinders. Typically a small residue is left when oil is burned by
the pistons. Also, it interferes with the normal combustion and
reduces power. I have an old car with 325,000 miles on its original
engine. It hasn't had the "benefit" of having oil in it's cylinders
and the engine runs fine.

I agree that the problem is more than likely the valve seals. Toyotas
are known to have these problems. These jobs can run you up to $1000
sometimes. But be wary of unscrupulous mechanics. They'll try to
convince you that you need an engine rebuild. Burning oil is mostly a
sign of the piston rings wearing and hence needing a rebuild. This is
not true of the start-up smoke. If it's bad enough it will even smoke
constantly. A compression test normally proves that it's the valve
seals. That's why I work on my own cars.
