they are 17lb injectors right? I feel i may as well replace a lot of stuff as the engine has 303532.4kms on it. the gaskets on the valve covers were cork, but appeared to be really thick plastic, leading me to assume that they are the factory original ones, so this engine is getting a complete overhaul as I get money.

 

Hey bro, I did the same with my 2.8L V6, if the valve cover gaskets were that hard then yeah they were original, the covers wont come off unless you take the upper and lower intake plenums off, wich is alot of stuff to get out the way, if you got any ?'s hit me up I will be happy to help..
