I've owned my 914 for 15 years and close to 40k miles now and never had the engine out! But I haven't used it much in the last 5 for several reasons.

The biggest is it shifts poorly, and it was dripping both motor oil and gear oil out of the bellhousing. I also had never done a deep dive for rust, but some holes that appeared where the floor and long meet under the driver's seat have convinced me now is the time (I'm 66 yo and afraid it will get "stuck" on the jack stands rather than being driven).
So far, the chassis is really very solid, but there will be more revelations and questions about that to come.

I dropped the entire drivetrain and separated the motor and trans thinking I had a rear main seal leak, but instead it turned out to be the camshaft sealing plug.
I found a lot of directions for pulling, tapping the rest of the oil gallery plugs (which I will not be doing), but no specific mentions of this larger plug.
Is it the same drill a hole, put a screw in and pull it out, followed by gluing a new one in?

Thanks in advance - more questions to follow

Scott

Yes, split the case wnich means tearing the motor apart is the way to fix that. They have rubber coated cam plugs now that are supposed to work better, which we have for upcoming motor projects.

However, unlike the oil galley plugs, there is no real pressure on that camshaft plug (unless you have excessive blowby creating unusual pressure inside the case). Depending on our mood at the time, we might be willing to clean that plug and old sealer up very well (get it super clean, maybe even use fine sandpaper) as it sits and use Hondabond or an appropriate sealer and see how things go. Your call.
