I can almost promise you knowing now what you've posted, if you buy this you're doing a cam and lifter job. If you stick with stock, buy ALL NEW Mds solenoids along with all the other necessary parts, and lubricate the orings with something like sil glyde or super lube. I have never been able to remove a factory one, even on a 16k mile car, without destroying it. They are known to collect metal flakes and shavings like the oil control valve(which i would also replace while in there).

Since this is in a car, its gonna be an easy job. Please let us know what happens!
