Good Day,

I'm in the process of scrounging together the parts necessary to do a replacement of all the key parts of the OEM sequential rats nest. If the hivemind could please sanity check the list below to make sure i've captured the right quantities and part numbers, it would be greatly appreciated.

Any recommendations of things to do "while you're there" that are worth addressing at the same would also be great.

Thank you for your assistance!

1 x Kit - SakeBomb Garage - Includes all the hoses and check valves so no need to order the mazda hoses or the following check valve part numbers: HE41-13-995, N390-13-995A1 x N390-18-741 Solenoid Turbo Control (On Rack)

1 x N3A1-20-285 Solenoid Duty (Wastegate & Precontrol)

1 x N3A1-18-741 Solenoid Turbo Control (ACV – Vacuum)

1x 1480-13-240A 3-Way valve

1 x 1481-13-240A 3-Way Valve

1 x 1482-13-240A 3-Way Valve

1 x N3A7-18-741 Solenoid ACV Switching (On Rack)

1 x N390-18-741 Solenoid ACV Switching (On Rack)

1 x F285-18-741A Solenoid Purge Valve (Mitsubishi Part)

1 x N3A1-13-720 Solenoid – Valve Air Bleed

1 x NF01-13-890 Valve – PCV

1 x N3A1-13-890 Valve – PCV

 

the list looks right to me. if you're on a budget the solenoids that don't do critical things, like EGR, and Purge can be checked first, they are probably ok . the important ones are the turbo control solenoids.

 

FYI,
I bought some new Mazda solenoids in the last year or so. These are from OEM Mazda directly (from Ray). Half of the solenoids tested bad, brand new. They leaked or didn't hold pressure or even some leaked vacuum too. I returned some for replacement. Be very careful and test every single one of them as per the thread in this forum for testing them with a Mityvac at room temperature and hot around 180-200 degrees F.

Is the failure rate of the OEM solenoids due, in part, to the fact they may have been sitting around in inventory for a very long time?

 

Like you, I believe that is the likely the cause. There is a thread I read in the past on the forum about putting type of oil in the solenoid to help lubricate the seal, but I didn't want to mess up a new one, so I just returned them for replacements. I had one leak a little still, so I used it for the emission stuff.
