Broken injector
 

Oops!
Taking off the injectors to replace them today and one of the tips broke off and fell into the intake. Not a big piece (smaller than a 1/8 inch square) I tried just about everything to get it out without taking the manifold off. I really don't want to take the manifold off to get this thing, do you think a little piece of plastic will harm my combustion chamber?

I don't think you want foreign objects being crushed and burnt by the piston, or valves being jammed.
