As I was swapping my heads and intake this weekend I noticed one of the orange ends of one of the injectors had broken off. I found the piece cracked in half in the injector hole. Do I need a new injector? Or will it be fine? Here's a pic:
That's just the pintle cap. The pintle caps hold the O ring in place and keep it from sliding off and into the manifold. If the correct pintle caps are used, they do not have any effect on the injector spray pattern.
Fuel injector seal kits with 2 O rings and a pintle cap (Borg-Warner P/N 274081) are available at Pep Boys auto parts. Cost is about $2.74 per kit.. The following are listed at the Borg-Warner site ( http://www.borg-warner.com ) as being resellers of Borg-Warner parts:
Most of the links above have store locators for find a store in your area.
Use motor oil on the O rings when you re-assemble them & everything will slide into place. The gasoline will wash away any excess oil that gets in the wrong places and it will burn up in the combustion chamber.
The pintle caps fit either injectors with a pin sticking out the injector end or 4 with more tiny holes in the injector end
Place the new pintle caps in some boiling water prior to trying to install them. It makes them soften up and easier to install.
