I have a 2000 Toyota Avalon. I can I tell if I have a sludge issue?

To really determine if you have sludge you'd have to pop off a valve cover. "Reading" the oil filler cap isn't good enough, as there are sometimes "natural" deposits on that. Once you see real sludge, you'll never forget it.

Mine is an '05 touring I purchased used. I found a small "spot" on my garage floor- Took it in and was told VVTi hose- out of warranty- will run you 420 to fix. I Laughed and got online and found parts for 91 shipped to me. Did the work myself- took my time and really cleaned the area in question. Good as new- no leaks. As for an improved hose- the number in the tsb has been updated to a different part number- the only difference I see is that the hose clamps look more substantial.(mine was leaking at the upper clamp)
If you are mechanically inclined - do it yourself and save$$-
All parts were available and shipped to me in one week.

The real fix appears to be a Toyota all steel one piece line that is available as a direct replacement for the metal/rubber line currently being used. It is my understanding that for defective hoses on vehicles still in warrenty, Toyota will allow the steel line to be installed at no charge as an upgrade, if the customer will buy the steel line (Approx. $28.00). I saw one site where someone was offering to replace the metal line in his garage for $50 labor.
 
It seems to me that the leaks and ruptures with the rubber/metal line will continue unless the rubber line is replaced at regular intervals, and no one seems to know what that mileage number is. Toyota seems content to just replace the rubber line at this point, and minimize how much engine damage can been done if a rupture happens while driving.
 
I don't know how many 2GR-FE (V-6) engines are out there since 2005 with rubber hoses, but it's a bunch. I would expect this problem to continue to escalate for Toyota, maybe even to recall status.

I'm going through the same thing right now. The dealer tried to charge me about the same money.I was wondering who you went through for the part any help would be greatly appreciated.

Do current production, 2009 Avalons, have the metal line? If so, what was the build date for the change from rubber to metal? Anybody know?

If I was crawling under the car (as I do when I change the oil) where would I see this part?
 
Can I also assume from the VIN that the problem was only for 2005 models?

Mr. Shiftright, you are confusing the VIN Number information for the TSB on a specific 2005 leaking oil line fix, with the real problem.
  
 All Avalon 2GR-FE engines from 2005 at least to 2008 have been manufactured with the metal/rubber oil lines that are now failing. I am reasonably sure this applies to most other models (Camry, etc.) with V-6 engines.
 
The oil line in question is easily viewed from the top of the engine compartment, on the passenger side by the shock mount tower. It is a shiny metal line about 3/8" in dia. that comes out of the top of the valve cover and turns 90 degrees straight down. After about 6", and just before it is covered by a plastic timing cover, there will be a rubber hose/hose clamp showing. This is the rubber portion of the two pc. line.

Oh so you are saying the line in the TSB is not the same VVT-1 line we are talking about? Let me look for other TSBs---seems if these were failing a lot we'd see something about it...so let me go dig some more.
 
EDIT: Okay, didn't see any other TSBs for this issue on later model years in the All Data file or in NHTSA, or anything about Toyota authorizing a metal line change.
 
Where did you see this info? I'd be interested.
