Are you sure it is the wear pad for the injector hold down? It kinda looks like a rivet and that would explain the loose injector too.

i will show a pick of it.It deffinately is a rivet though like a rivet that was never popped still has the shank on it.

Is this new or did you just take the cap off messing around and see that it does that? I get a little bit off mine, it's just the nature of the engine since lb7s don't have a pcv system. If you're really worried you could take the crankcase breather hose off of the alternator bracket (down by the fuel port under the alt), hold your finger over it and take the oil fill cap off. Then flip the oil cap upside down and set it on your oil fill pipe, if you have enough crankcase pressure to blow the oil fill cap off the pipe then you've probably got a problem. If the cap doesn't move then I wouldn't be to worried about it. This is just my opinion though :thumb:

I was just going to post that I have seen this happen when a hold down broke and the injector was no longer seated, .
