Hiro, I think you might be right. I’ve discovered the part number to be 17380-63010. Looking online I found attached diagram. Link here. What isn’t clear is how the parts highlighted in green on the rod connect to the valves. Visibility is impossible underneath the rod. See photo attached from the top. But I guess the main question is, do I bother replacing the actuator (which is expensive) or can I just seal up the diaphragm relief hole (presumably meaning the actuator will no longer move the rod)? If it’s just for better swirl/vaporization at idle, does it really matter? Thanks.

Thanks Tony. I've actually just found out it is connected to an oil distribution rod with small holes in it, next to cam shaft. To me this suggests it moves back and forward to provide better dispersion of oil over camshaft at high (or low) revs. Does this provide better clues as to what this part is?

Hi, New member here and have a bit of a challenge for any mechanics out there. So far no local mechanics in my area (I'm in Perth WA) have been able to solve this, nor in US forums where I posted the same question. Vehicle: 1989 Toyota Camry 4 cylinder sedan. Model: SV20R-EPBLA Engine: 1S-CI Trans: A140L Date: 05/89 Problem: The part as shown is leaking significant oil out (when engine running) from what appears to be a vent hole in the part as shown. Please refer to photos attached. I have no idea what this part is or what it does. It appears to be some sort of diaphragm actuator from the vacuum system but not clear on what it is actually 'actuating'. It seems related to control of oil into the engine block perhaps. It is connected to the engine block in the location as shown circled in yellow. The vacuum hose that was connected to the part is shown marked in red. I've searched the manual in vein. Only diaphragm actuators I could see related to the EGR system or cruise control but these are not related. As mentioned it seems related to oiling quantity control? Any clues or advice on this would be appreciated. The part (I'm told) is not common and the mechanic I'm currently dealing with has said the vehicle is a throw-away because of this. I'm not convinced we're at white-flag waving stage yet. Looking forward to any replies. Thanks.
