1.6TD injector spray pattern

(1/1)

The spray pattern differs a bit between my injectors. They both pop around 2000psi. The Bentley says "check that the injector sprays in an even, compact cone pattern...". How compact/narrow should it be? I'm worried that an incorrect spray pattern can damage the precups, but the Bentley isn't very specific on what the spray pattern should look like.

libbydiesel:
Those are both fine provided they both pop cleanly at a similar pressure and don't pee streams below the pop pressure.

fatmobile:
"and don't pee streams below the pop pressure."
I bought some new bosch injector inserts,..
 and they pissed worse just before breaking pressure than some of the old injectors I have.
They were made in brazil ,.. I'll buy india made nozzles next time.

It is just miserable having to wade through so much dross these days, parts wise.
