EXACTLY what is / has happened to our Highlander--except the replacement of the PCV valve. I believe you, I would just like an explanation why that would be. I have recently found out I might be a victim of the "sludge/oil gelling" issue and this is the FIRST time I heard what YOU are suggesting. Most of our miles have been "local" and this issue came to light when my family was almost stranded 1600 miles after a full oil/filter change. Just completed a 1200 mile trip (from 60-73mph) through parts of Illinois and Missouri and consumed 6 quarts of oil. All is recorded with various Toyota dealers, but that was not good enough for our local dealer. He wants us to come back in 500 miles and check. This would be a "God-send" if this is really the cure for our 2002 with, now, 90000. I keep hearing more and more about the "gelling" issue, but the front valve cover was pulled and showed no obvious sludge. I was ready to invest in all synthetic oil and start changing at every 3/3 though Toyota maintains 7,500 is the standard. If this proves out, I will owe you the best dinner I can provide ! ! ! By the way, why did you suspect the PCV!?
Why doesn't my "plugged-in" dealer know about this???????????????????????? If this problem has existed for a while wouldn't seals, or SOMETHING be damaged?
#4938 of 5330 Any feedback?

I just ordered a K & N filter element for my 4 cylinder Highlander and wonder if anyone has any comments. The local dealer raised his price on stock filters to the point where a K & N seems like a bargain and many people claim they also perform better.
During the last service the dealer service adviser also mentioned that it appeared that my water pump had been leaking and it was probably a good idea to replace it. On the 4 cylinder it is a much easier job than on the 6, but I don't see any point in getting it done until it is leaking a significant amount or getting noisy. Again . . . any ideas?

Be careful about having them mess around with your water pump. It could just be your condenser. Check your radiator if you are losing water. That is the sure way of making sure if your water pump is leaking. Just remember not to uncap your radiator while it is hot. I got a 2nd degree burn on my arm 16 yrs ago because of my stupidity. By the way, I've had my share of nightmare with the toyota dealership. They seem to be all passive aggressive. GOOD LUCK.

Most water pumps have a built in "weep" hole/opening so that any coolant that does get through the seal protecting the shaft bearing does not remain inside and "fail" the bearing.
Over time this leakage will leave a trail of coolant chemicals and the (S)dealers will often point out this trail as evidence of a failing water pump.
So I would not rely on the dealer for an opinion but I would begin watching the coolant level for time to time or watch out for pools of coolant under the water pump area of the engine.
If you mean the oil firm type of K&N then STAY AWAY, worse than snake oil as over time it might, will often, result in damage to the MAF/IAT sensors.

Did you end up replacing the wheel bearing yourself? I think I have the same problem and am trying to decide if I should attempt it myself.

My OEM battery is starting to get tired after nearly 3 years in this Texas Heat. I was considering an Autozone Duralast Gold battery to replace it. Anyone have anything positive/negative about those batteries, or any other battery?

It's almost a crap shoot, but, Consumer Reports has some good information. IIRC, the Durlast batteries are pretty dang good. Especially at their price point.
However, I'm a bit surprised you battery is giving up the ghost after only 3 years. I had my OEM batter in my '03 for six years and after only one cell died I decided not to push it any farther and got another OEM.
However, as with most things, YMMV, which it obviously does.

The last I heard, most car batteries in the US are supplied either by Johnson Controls or one other company (Exide, iirc).
I've had good luck with batteries from Walmart in Boise heat (but only ~3 months of heat a year). Who knows who makes those - I've heard that both companies source for Walmart depending on the part of the country you are in. AutoZone is probably similar.
Six of one, half dozen of the other?

I have used the Autozone batteries for about 3 years now in a few vehicles. Replaced the OEM in 05 Highlander after 3 years. The red battery has more than enough cranking power. My wife does lots of short trips so far so good!

Gee, my '03 battery lasted nearly 7 years!! And it gets pretty hot in Fort Worth too!
I live close to a Sears, and after triple A left, I drove straight there and had one of their "big bopper" batteries installed! Of course it must be considered that I still have less than 50,000 miles on this car!!
