I could not access the rear o2 sensor (upstream?)
It was too tight for my tools

I had my mechanic take a look at it and he called to tell me he broke it off and I need a new exhaust manifold. WOW!

Any ideas on whear to find this manifold at a reasonable price?
Possibly a used one or toyota ``?

i bought one from dealer and it was around 350.00 new i thought that it was going to be over thoushand dollars when i caled lexus, and was very surprised when he gave me the price.

Call around to a couple of salvage yards in your area. They might have one that you can get pretty cheap. Just make sure it doesn't have any cracks.

If your mechanic broke it than he should pay for it.
