Hello All,
I'm new to the site. I have a 98 3.0 Sienna with 104K miles. Runs like new and I plan to keep it that way. I'm big on preventitive maintenance. All regular scheduled maintenance has been done and the only thing I'm concerned about is the life expectantcy of the oil pump. I'd like to get some statistical idea of when I can expect it to fail so I can plan to have it replaced ahead of time. Thanks for any help.

the only thing i can suggest to is to get a mechanical oil pressure gauge because the time of failure isn't known.

mine for instance failed at 100k. so i ended up replacing the entire engine due to the fact that the dummy light tells you when it's too late. so with this new motor i have a gauge and it stays at 15-20psi when idleing. any lower then 10psi problems are in the future.
