I have the plenum, injectors and the driver's side injectors housings off and had a few quick questions.
1. When I pulled the injectors off the passengers side I noticed every other injector had two o-rings on it and all but one of these also had a blue plastic cap. I presume the other blue plastic cap is in the injector housing, but I haven't fished it out yet. Does this mean I have a bad injector or can I just replace the cap assuming I can find it once I get the other injector out? I believe they are relatively new (<1yr) FIC injectors if that makes a difference.
2. The gaskets I pulled off were cut to match the porting, so I plan to cut my new ones similarly. I also had to scrape off a ton of permatex from the existing gaskets. Is it advisable use permatex when putting the new plenum, IH housing and IH coolant tube gaskets on?
Note: I also noticed that the gasket was incorrectly installed on the passengers side blocking off the hole to the IH coolant pipes.
Other than this everything is going OK - thanks to all the pointers I've received from the experts!
