That plastic manifold, pictured, is vastly different to the device on my 1.9 16v JTDm motor.
Mainly the manifold on my car is much smaller than that pictured and doesn't have the space for a slide valve. It also doesn't have an actuator which would be required to move them.
Assuming there are no swirl valves, or a slide valve, what will an EGR delete gain for the sometimes ridiculous costs some companies are charging ? I've seen a £200 EGR delete advertised. in terms of fuel saving, or performance, or driveability, will that £200 be better spent buying top quality diesel instead ?
Assuming I do have swirl valves, they're invisible and operated by a hidden actuator !
All of the replacement inlet manifolds listed anywhere, show an alloy replacement, which is a different design to the plastic version, and you can see where the actuator for the swirl flaps operates them. You couldn't fit one of these replacement manifolds to my engine because there is no actuator. Unless the new manifold arrived with an actuator, wiring sub-harness etc and instructions identifying the different types of original manifold, which I don't think they do, this black manifold system is unique, and the fact that i can't seem to find one listed anywhere suggests they aren't replaced very often.
EDIT - I just had this idea - does anyone know if the swirl valve actuator is visible using either AlfaOBD or FES ? I know the EGR valve can be actuated manually in software, but what about the swirl valve ? If yoiu have the old alloy manifold with swirl valves and a copy of AlfaOBD or FES, can yoiu check if yoiu can operate the swirl valves remotely, please
It's just that i don't remember ever seeing swirl valve actuator in the device list in AlfaOBD or FES. I presume that the existence of the device in the software program could be an indicator as to whether one is fitted or not ?
