Hi everyone, new to the forum but not toyotas this is my 4th, But my first 3.0 and ifs. Couldnt pass it up for 400,but needed new timing belt and everything on the way out. Also rebuilt all the fuel injectors and anything between there and the fuel tank all new. A little about the truck has a 3 inch body lift and 2 inch suspension(working on refiguring the rear shocks).Tires are 33x12.5x16 not a fan of these tires on this. Now im in the process of removing the egr and have a question about the valves on the pass. side fender. I Know the red is the fuel not sure about the other 3. They go in the order from the front of the truck grey, green , red and blue. Hoping to post some pics of it here shortly of the truck and the valves. Thank you in advance

did rebuilding the fuel injectors make them quiet? Mine work okay, just click click click.

The pair or AS help power by keeping exhaust volocity for higher scavenging affect.

I cant really say rebuiding the injectors made them quite compared to before. The truck was really only running on 3 cylinders when I got it. I know some injectors are just louder then others, bought my chevy truck fresh off the line with only3 miles on it and the injectors were loud. And for the pair and egr it was removed due to that it was not working

It's not the injectors that make the noise on the 3.0's, it's the fuel pressure regulator. There's nothing wrong with it, it just clicks.
