Decided to tackle the header swap today! All was going well, even after the entire stud backed out for 4 of the 6 studs on the passenger side
Ordered new studs and nuts from Toyota and I'll install them next weekend when I do the drivers side header. I ran out of time today. Got em finished up... Or at least the passenger side.
BUT of course, my ****ing luck, when trying to retrieve the upstream O2 sensor, it decided it was gonna stay behind. Now I did notice however that the threads were messed up, so I'm thinking Toyota messed them up when they replaced my transmission.
Got a new one from NAPA for $226.24 because autozone didn't have any in stock (theirs was $154) and I made sure to put a shit ton of anti seize on it.
Got the O2 simulators installed as well and no more CEL, so I'm happy. Can't wait to get the other side done! I just hope I don't have another issue like this with the sensor breaking.
There went my Arizona money....
The truck sounds kinda awesome already. You can hear a different tone in the engine. It's nice.
