I had one of thema long time ago and I checked it out then and seemed to operate the same. I have not checked the new one i just got but i was thinking on doing this mod myself taking old solenoids and modding them. The sealed units originally came from a motor that was nissan and never imported here. I am hoping that the pushrod extends the same distance and i am pretty sure it does but i will be mic'n it soon b4 i put on motor to test. I really want to paint the motor and everythnig else white to trace down oil leaks just as they happen to see where the weak spots are. eh jk
