A question and an ask SBM 318

That plug behind the cam plate has always been there when I take them apart.

Were they virgins or had someone been in there?

I’ve never pulled apart a virgin that had them.

IMO they are a waste of time. The OP could have the front of the engine together by now if he would have just moved on.

I can say in all my build since 1980 I have never used core plugs there. Not once.

But I never used the stupid bolt with the hole in it or the drip tray either.
