I am working on my 05 4.0L V6 Mustang and when I took off my valve covers I noticed this piece was broken on one side but I dont know what its called to get another one can you help me out? And is there any reason you can think of for how it might have broken? We think theres something wrong with my timing chain because the car wont start. Instead of making the "eh eh eh eh eh" sound it would normally make trying to start its making a constant "eeeeeeeehhhhhhhhhh" sound and it has a slight backfire "pop" coming from the exhaust.
Does any of this sound like something you've experienced? The engine is out of the car and on the engine stand.
