Default sludge on a 2001 V6 Camry?

Hi, we just bought a used 2001 XLE V6 Carmy and I was dumb enough not
to do enough research on it until I actually bought it. Anyway,
everything is great with this car that we bought with 43,000km on it
and I have the complete service records including the oil changes.
Anyways, I opened up the oil cap on found some sluge on the inside
cover. It was not on the cap (it might have been wiped off earlier)
but the sludge was enough for me to scrap it off with a cloth with my
fingers. Anyway, it was not too bad but I wonder how it would like
with the valve cover off? I would say the inside cover was covered
with about 1mm of sludge or so. (it feels like sand)

Also, is the Toyota Canada sludge problem warranty good for Canada as
well? I believe it's the 8 year unlimited milage warranty on the
sludge problem. I do not notice any blue smoke on the exhaust and the
oil dip stick looks clean.

Should I be even a little concern with the amount of sludge I found if
I continue to do my regular oil changes at 5000kms? Would the sludge
go away with more frequent oil changes?

What you are describing is not exactly the sludge problem that destroyed
some
V6 engines.

If I were you, I would change my oil at 3000-3500 miles, using a good
quality oil.

I personally use Castrol, but you use what you like. (There are some brands
of
oil I don't use anymore because I believe they contribute to varnish
formation in
the engine.)

I do not use synthetics, but dont have too much against them except for the
cost.**

I believe the most recent issue of Popular Mechanics discusses change
interval a little, and
the 'expert opinion' is that you should change often EVEN IF you use
synthetics**.
The reasoning is that both refined fossil oil and 'synthetic' suffer from
contamination
due to engine blowby, wear, dilution, etc, and regardless of the superlative
specifications
that are quoted, the lubricants should be changed frequently.

Toyota says that V6 sludge related failures are almost always related to the
failure of
the owner to change oil frequently enough.. (Interesting that, it is it
said, Toyota may
have had to change its corporate opinion of how frequently 'enough' actually
is):

One of the benefits of synthetic oil is higher resistance to thermal
breakdown - that is, can be operated at higher temperature without
atlering viscosity.
Other benefits are higher film strength and lubricity.
As you say, for normal driving, these beneftis may not be worth the
additional cost, but they can be helpful under more extreme conditions

There is a plastic deflector just below the filler cap that usually develops
a thin film of oil that you are observing. That is not engine sludge, and
has no bearing on whether there is or is not sludge inside your engine.
Because of the deflector, you cannot see inside your crankcase from the
filler cap to determine is you have engine sludge.

I would recommend synthetic oil, or at least a synthetic blend for you car.
If you have not used synthetic previously, I would use 10W-30 instead of
5W-30.

A call to your local Toyota Dealer service department will answer the
warranty question that you have.

Yes, I'm planning on calling the dealership soon but this whole weekend
is a holiday including today. I'm pretty sure it's sludge that was on
that plastic deflector. It's not a thin film of oil. I had to poke my
fingers in there and scrap it off with a cloth. The substance on it
was like black sand...it was all over the deflector.

Regarding the 2001 Camry we got, it drives great. We have been drivng
a Camry for the past 12 years and just replaced our 92 LE V6. Only
real problem we had with the 92 was the water pump, radiator, small oil
leak, shocks. The Camry was just so reliable that I didn't think twice
when buying our new one which is fully loaded with everything.

You are not listening. The sludge (or whatever it is) on the plastic
deflector is present on most V6 Toyotas regardless of whether there is any
sludge inside your engine. I have used Mobil 1 since 5000 miles and change
it regularly, and still have the stuff on my deflector.

That is not sludge. It is sound deadening material applied to the top of
the baffle to minimize noise from the valve train. You will see it in a
brand new vehicle.

Where's Charlene Blake to contribute her infinite wisdom? ;-)

Your joking right? Either way...I don't get it.

I guess I'm being a little paranoid but I'm going to the dealership
tomorrow to check it out and some used ones on the lot.

Unfortunately synthetic oil is the solution next to getting rid of the
car and let the next owner, like you, worry about it. Some engine
designs, like the Chrysler 2.7 V6 (but not the 3.5 V6, go figure) and
VW 1.8t (we know, it's got turbo) have the same problem. VW specified
both the brand and weight of approved synthetics to use, and they
increased both the sump and filter sizes in that case.

Elevated cylinder head temperatures, probably due to the ULEV needs and
the removal of the engine oil cooler in 97 (cost cutting) may be the
reasons for these engines sludging up. As you know, they don't build
them like they used to. But you do get the 8-year extended warranty
that you'll have to pull teeth to have it honored (why don't you try
it?)

Mark is right, what's on the shield may not be what's in the cylinder
head. That said, the splash shield under the oil filler cap should have
no more than a thin layer of brown engine oil. No more -- not gritty
stuff you can scrape off. It may not have a problem, but rather than
waiting for the warranty to kick in, try finding another car without
this problem.

The buildup on the plastic splash shield is not a problem. I have it on my
98 V6 and I have used Mobil 1 since 5000 miles. When you pour the new oil in
the crankcase, it flows over the plastic deflector and a sticky reside
builds up. The more often the engine oil is changed, the more likely the
deflector is likely to have the residue.

Do not look for another car unless you find some other evidence of sludge.
