Poor prechamber seal, or poor injector seal.

Injector sealing washers are cheap, try that first. If you *do* need to pull the PC, be sure to pull the glow plug first.

Nope. You can rent a fancy puller tool to get it out from the top. But you absolutely have to remove the glow plug first. Also, the PC seal and injector seal will need to be replaced.
