I agree with all that. =C2=A0Something to keep in mind is that what is hap=
pening is suction. =C2=A0The end of the pushrod is fitting snugly and perf=
ectly into the tappet. =C2=A0Add some oil into it and you've got this conn=
ection that when you pull up on the connecting rod, it's the oil and this =
perfect fit into the cup of the tappet that creates the suction fit you ne=
ed to break. =C2=A0So to Randall's point of having the tappet low, that wi=
ll give you more travel pulling up to break that suction before the tappet=
 comes out of it's slot.=0A=0AAs Randall said, worst case is you'd have to=
 take the head off, but as I said, I had this happen to me and with some p=
atience, a long screw driver, I was able to get mine back into place in ab=
