I changed injectors last Friday and over tightened the 2 bolts in the back that has the injection lines on them. The gasket must have been a bit brittle and split and blew out. I only removed the lines to 1,2,4, and the plate came out the front. Now the problem that I see is getting the plate and the gasket back in there together. I was wondering if it would be a problem if I put something like silicon or grease or gasket shellac to hold the gasket in place or is it a no sealer type of gasket.

No sealer. I did the same thing, I think I put the plate in first, then snuck the gasket in. 

Maybe you can get a couple extra bolts of the correct size and cut the heads off. Start these in 2 of the holes. Drop on gasket then plate. This will keep everything lined up. Not sure if you have room for this. 

I would remove all 6 lines and do it right. Still need to scrape off the old gasket material kind of tough with all the other stuff in the way.

Well I think I will try to sneak it in with the plate. The old gasket came out all in one piece and it is as clean as if I already scraped it. I did try to clean the inside edge where the dirt builds up and it looks as clean as it has been since new.
