I'm Awesome
So I noticed a little bit of residue in my oil filler cap, which I think was dexcool residue, so I decided to replace the intake gastets, and tackle all of the "while you're in there" jobs at the same time. Tuck is a 97 yukon 2 door with 5.7.
The Delphi and AC Delco mfpi kits were sold out everywhere, so I found a kit from an eBay seller who operates a retail fuel injection store. He explained that he uses Delphi injectors and only reuses the central distribution block in his kits, and it was priced similar to the AC Delco, so I bit.
When I went to install it, the injectors would not seat to save my life. The white plastic was jamming, almost like it was too big. I called the seller and he said to clean all of the carbon from the manifold, which is often an issue with conversions, so I went to town and got them sparking clean with a series of nylon brushes and carb cleaner. Still, injectors wouldn't even come close to seating like they do in all the you tube videos. A dab of sil-glide didn't help at all. It's on all 8, not just a few. Also, in my struggle, I broke one of the injectors and I feel like an idiot. Should I have loosened the retainer at the bottom before trying to rotate them?
First question, am I doing something wrong? Is there a trick or technique to dropping them in? Are there different manifolds I'm not aware of?
Second question, whats my next step? Should I buy a single AC Delco injector to replace the broken one? Can I replace just the plastic tips on the others if it fits better?
