Replying to: mbs171 (Jun 16, 2009 2:39 pm) 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. |

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?

Replying to: Mr_Shiftright (Jun 19, 2009 4:32 pm) Can I also assume from the VIN that the problem was only for 2005 models? |

Replying to: Mr_Shiftright (Jun 19, 2009 4:32 pm) 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.

Replying to: Mr_Shiftright (Jun 20, 2009 5:44 am) Please note that this TSB does not change the two pc. metal/rubber line design, it only replaces a defective part. As I mentioned in my previous post, Toyota has continued with the metal/rubber line at least thru 2008. The major problem seems to be that there are now rubber hose ruptures occuring while driving down the road that allow loss of almost all engine oil very quickly. There are multiple posts about the oil line problems on this site and several other websites related to Toyota vehicles. Any search engine will take you to at least 3-4 sites if you just type in VVTi oil line leak/Toyota. There is no recent TSB from Toyota on the issue. There is a direct replacement all metal VVTi line (15772-31030) in the Toyota parts system. This information was posted on one of the Toyota owner sites because some owners are replacing the metal/rubber line at their cost BEFORE problems occur. |
