2008 Highlander owners beware.
The 2GR-FE engine has a oil line with a rubber hose between 2 steel oil lines that is failing often with no warning. It is the oil line from the oil pump to the VVT (variable valve timing). I have read many many forums and owners are seeing this rubber hose portion of the line split at about 45K miles to 75K miles on 2005-2008 Avalons, RAV4 and Camrys so far. The 08 Highlander has this line also. Owners say their is no warning lights that come on. Most see a pool of oil under the vehicle, smell oil while driving or the serp belt starts slipping on the air conditioning and it acts up because oil is spraying all over the engine. Some have been lucky to stop the engine before they wrecked it, some have not.
Toyota knows about the issue, from a lot of mad owners, but since it does not involve safety, a recall has not happened. No TSB has been issued on the hose rupture problem either. One was issued on the 05 Avalon but was not addressing the hose rupture problem but a hose clamp issue. If the line ruptures, the dealer will replace the hose under the 5yr/60K mile drive train warranty. Some owners have had major engine issues because they didn't stop the engine in time. The 09 models that have the 2GR-FE engines have a solid steel line to solve the problem once and for all.
The one end of the line is located at the top of the engine, passenger side by the shock mount tower. It is a 3/8" dia line and turns straight down to the lower part of the engine. After about 6" of the steel line, the rubber hose is attached by clamps and is then covered by the plastic timing cover and heads to the lower area of the engine.
There is a good write up with pixs at: www.rav4world.com/forum. See post #134. Also, if you google search Avalon oil leak you will see many different forums that contain horror stories from owners of this engine on many Toyota models including the 08 Highlander.
I don't think this problem is getting much discussion in the 08 Highlander forum is the reason I'm bring it up here as well as on Avalon forum. I have both models and thus 2 engines that could loose all the oil with no warning. So 2GR-FE engine owners beware if you don't have an all steel line you have a potential problem that could turn into a major problem.
