egr solenoid valve is broken and so is the check valve on the tb can i use the switching solenoid valve and another 1 way check valve like what goes to the solenoid valves?

 

i don't believe there is any difference in any of the valves themselves aside from the positioning of the vent and lines on them. the valves are simple 12v solenoids which open and close when given voltage and ground to allow vacuum to pass. the painted stickers are just for locating and identification purposes but mean nothing aside from that.

any simple one way check valve will work for the line.

 

I appriciate it. But i went ahead and just removed the rats nest and did the tb mod.
