Greg, are some of your timing cover studs broken off or something?
Curious to know why there would be a question. Not being smart, really;
just wanting to help, if I can.
If I understand you well enough, I think those are threaded studs, aren't
they? They look to be fastened with nuts....so I think your answer would
be yes.
I think you're asking about the two bottom left of the timing pointer,
I call it, but that might not be the correct reference.
