Loud secondary air pump
My 97-528 SAP is kind of loud compares to my 02-530.
It's a fast loud thumping sound.
I think the air passage may have been clogged, but then again this maybe normal for 528.
How's every 528 SAP sound in the morning? Thanks for the feed back.

Good job on isolating the problem:thumbup:
Before you do that seafoam madness, try removing the valve, and let it soak in WD-40 overnight. If the valve is partially sticking mechanically, this soaking will free things up.
If the valve isn't opening up due to other issues, like a diaphragm malfunction, then most likely a replacement is what's needed. :dunno:

Glad to hear !
So what exactly is this Seafoam supposed to be cleaning when it's poured down that large hose?
Looks to me like if I poured Seafoam down this hose on my '98, it'd go down directly to the pump, would it not?
I think the part needing a Seafoam cleansen is the valve itself, isn't it?
