Mine got so rusted (dipstick tube) I could no longer pull the dipstick out and once out was not able to put all the way back in, even with fresh grease on the O-ring. Advanceautoparts.com had the dipstick tube and dipstick for a reasonable price. They are identical to the original Toyota parts
I just got Walker cats for my gen4 T4R, almost half price!
Glad I stumbled on carid.com amazing prices overnight delivery to NJ
I just replaced both 2nd stage cats on my 2008 V6, spent about half
of what a local auto parts store would charge.
