I'm thinking the knocking that goes away with time when you put in new nozzles could be the seal is not good, and in time it cokes up and makes less noise.

I am now thinking the noise from my injectors/oil cover area must be prechambers. My reasons are 1. Brian Carlton described the follower noise as a regular and sharp metallic sound. My sound is not regular or sharp.
2. Injectors/prechamber noise sounds louder near the rear of the wheel wells. Mine does.

So it must be injectors or prechambers. Since the sound isn't coming from one source that I can identify by undoing the injector lines one at a time, I am assuming (yes, dangerous) it must be prechambers. Guess I'll have to pull it out and see. I have the tool rented from someone on the forum. And I'm going to get a slide hammer and hook it up to an old injector body and have a go at getting the prechamber out and putting a new seal in for the injector. There is a crush washer / seal stuck in there and it's not in good condition. I read some guy fixed his leaking prechamber by taking it out, cleaning it and aputting it back. If that doesn't work, there are pcs for sale for under $100 on the internet.

Do you see any illogic or errors in my reasoning? Is there a better check for pc problems?

Thanks
