1999 ML 320 Seconday Air Injection Valves

Hi Eveyone,

I'm new to the forum so I hope I'm posting this quation in the right spot.

I just pirchased this vehicle and I have fixed everything that needed fixing except the Code for the Seconday Air Injecting system.

I have removed the entire system and I found a ton of carbon build up I replaced the cross over valve and all the vaccum lines they were all in bad shape.

Thye motor is fine it runs just like it should but the reed valves under the vacumm valves are in rough shaoe I have tried soaking and claeaning them up, but I have read all the posts on these two valves on the forum and one thing remains constant. The reed valves must lay flat and now matter what I do they are both opened about an 1/8 of inch.

Does any one know where I can just buy just the replacement valves and not the entire unit $217.00 each. The vacumm modlues are fine the diaphrams are work fine just need the valeves them selves.
