Default Is it ok to drive? 92 Bonneville SE

I recently posted that I had a fuel smell and I after more serching I found a leaking O-ring on an injector. When I pulled the injectors out I noticed one of the plastic or ceramic pintal caps that directs the fuel spray into the intake manifold was cracked and fell apart in my hand. I have been unable to find an injector repair kit (just O-ring kit) locally so I ordered a repair kit for Boche type injectors from E-Bay. It comes with little fuel screen, two o-rings, plastic spacer washer and a pintal cap for each of the 6 injectors.

I put the new o-rings back on all injectors and injector rail back on car and started it up. All ok so far. Now the question. While awaiting a few days for my repair kits to arrive, I was wondering if if driving without one pintal cape could cause damage to a piston, manifold or valve etc. with around town driving? I plan to repair all the injectors at the same time. Car seems to run OK? Any thoughts welcome.

That missing PINTLE cap won't cause you any problems. If it lasted 3 combustion cycles in a cylinder I'd be surprised.

To clarify, The pintal cap did not fall into the piston, it fell apart in my hand after I had removed the injectors to change the O-rings.

The P I N T L E cap is only there to keep buildup off the injector nozzles. You don't really need them at all.
