Default 02 Camry 4cyl - engine noise


The 4 cylinder engine in my 02 Camry (67K miles) has been getting louder
and louder. When the engine is under load, right after starting it cold,
it sounds like diesel - like metal banging against metal. Its almost as
if something in the engine is not getting enough oil. Once it warms up,
it quiets down a bit, but it is still a LOT louder than when it was new 2
years ago. The noise level is very weather dependent. On very cold
mornings, its so bad that I'm almost afraid to accelerate for fear of
something breaking.

Took it to the dealer yesterday. They're telling me that there is
nothing wrong with it, and that this engine is known for being noisy
when cold. ???? The engine was first used in 2002 models. How can it
be "known" for being noisy?

I'm thinking of a few possible options: take it to another dealer?
Use one of those oil flushing additives next time I change the oil?
Switch oil types?

Suggestions?

There is a TSB regarding that complaint, but I am not sure of the VIN
range/ year off hand. I do remember that it is for the newer camry, 02 -
03, and it involves replacing the intake manifold. Apparently the
induction flow during cold startup causes a knocking-type sound. Should be
covered under the 3/36k warranty.

If your oil-pressure light is not blinking on at idle when the engine is hot
then its reasonable to assume the OP is ok,..but it would be much better if
you could have an OPgauge fitted to monitor it accurately.

I haven't been able to listen to one of those motors, but the 5SFE in the
preceding models is not what I;d call a quiet motor. The overhead gear seems
to be noisey and gets louder as the motor warms up and clearances increase.
It tends to inidcate piston rattle if the noise is loudest when the engine
is cold,....but as I said, it may just be normal for those motors especially
if you re comparing it to another make of car. As a rule, any noise that
gets louder on load, indicates pistons or bearings.

Hmmm.... I see a TSB 01804 (NHTSA #10008384) regarding intake manifold
noise on 02 Camrys. The website doesn't provide anything more than that.
Can anyone out there get the full TSB for me? I wonder if I can get the
dealer to print it out for me.

Thanks for the tip, qslim.

One of the service reps at your local dealer should show you the TSB if you
ask nicely. If not, they're dicks and you should go to another dealer.

I have a copy of the TSB now. While it does apply to my engine, I'm not
sure if that is really the problem I'm experiencing.

I have since taken the car to another dealer. I'll let you know what
they say about it.

Ummm.. I don't see how that will quiet the engine down.

I am inferring that you think perhaps I have not maintained the engine
properly. Just FYI, I change the oil and filter every 4-5K miles. I use
a non-synthetic brandname oil (usually Castrol), and premium filters
(Hastings or Wix).

Mobil is a 10-50 oil,..but I found it too light to maintain adequate
oil-pressure below 2000 rpm in a Cleveland V8 351,.....I'd use dino oil in
all but the newest of hi-tech motors.

Copied from :
Message 1 in threadFrom: Dirk Broer (broerd@kaos.gsfc.nasa.gov)
Subject: Synthetics part I
_____
"Film strength" refers to the amount of pressure required to force out
a
film of oil from between two pieces of flat metal. The higher the film
strength, the more protection is provided to such parts as piston
rings,
timing chain, cams, lifters, and rocker arms...wherever the lubricant
is
not under oil-system pressure. Synthetics routinely exhibit a nominal
film strength of well over 3,000 psi, while petroleum oils average
somewhat less than 500 psi. The result is more lubricant protection
between moving parts with synthetics.
------
The oil filters you mention are reputed to be of good quality, but why
not use the oil filter specifically designed for your vehicle by the
Toyota engineers who designed the rest of the engine?
The canister size, anti drain back components, filter media flow and
filtration are all optimized for your engine.
Just a suggestion - a place to start if you so choose.
