Hi all. I've been lurking for a while both here and STD and I love the great information that I've been mining. Thanks a bunch. I've got an '87 300d, and an old FJ40 that's about to get an OM617 swap from an '85 300d donor. My GF drives an '85 300td.

Has anyone seen this push-pull wastegate actuator?


See the lower port that's plugged? It appears to be plumbed to the spring side , which is sealed. I was thinking that for those who no longer have auto transmissions that the vacuum control valve could be used to vary boost pressure to this second port and effectively add pressure to the WG actuator's spring at light throttle.

I haven't seen mention of this actuator in either forums' archives. It seems so simple that I can't help but think that I've overlooked something obvious.
