say i cracked a couple of the little orange caps at the tip of the injectors... would it be cool to use them like this? what is the purpose of them? worst case?
if its not good.. ive heard of injector re-build kits.. where would i get one?
Not so good, I wouldn't recommend you use the injectors untill you get replacement caps. Go to eBay stores, Mr.Injector store, order you a rebuild kit. Replace all the o-rings, filters, spacers and caps.
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
