Thanks for the information. I had an oil leak. Sewell Lexus determined it was the timing cover which is noted in TSIB EG010-07 date 4/12/2007. They replaced the timing cover, VVTi Oil hose, underboddy plugs, driver's seat belt and added grease to the anti-squeal shim in the rear brakes. I asked for the metal version of the VVTi Oil hose but Lexus Customer Service Technical said they did not make one for the model year 07. The newer model uses an all metal line but I was told the shape and design of the newer VVTi Oil line was different and would not fit on MY07 engine event though it is the same engine. I suspect using an all metal VVTi oil line on bank 1 could cause a rattling noise between the oil line and the VV timing cover. Just a guess on my part. I've read others speculate this new oil hose should last between 10-15 years. MY07 ES350 (10/2006), 42K miles

The body shop manager for Sewell Lexus of Fort Worth, TX told us it helps to deaden sounds especially with noise from spare tire movement. He said the material is applied at the factory and he showed us other cars with the same material in the trunk. In our case most of area at the bottom of the spare wheel tub in the trunk was covered with this material. Some area of the trunk bed adjacent to the spare wheel tub also had this material.
