O.K. Time to deal with the Nailing in #1 cylinder. From what I've learned here over the last few months, I need to check:

1.) the injector nozzle, and

2.) the timing chain for stretch.

Questions re: nozzle. When I pull the nozzle, what pieces and parts do I need to be aware of? As in, are there seals or gaskets or grommets? Do I need to have replacements for any of these on hand? Once the nozzle is out should I try a basic solvent cleaning and then put it back in and test?

The chain comes later.

Thanks, guys.
