Frank,
Eat a cookie and relax a little
It will get better!
That is the question! (How did it get out?) If this is in fact the
oil pressure bypass spring...How did it get out? And what happened to the rest of it? Just a guess here but it's about 1 1/4" long in whole.
I can't think of any other place a spring of that size would be in the engine.
