well I have been searching about this ticking sound that has been driving me nuts since I changed it to the proper oil. Obviously the guy who sold the truck put thicker oil in to quiet the tick, good thing I changed it. So im gonna fix it right. I have narrowed it down to the rear cylinder driverside lifter/lash adjuster. I have done some research and deep creeped everything I believe is coming off to get to the valve cover. The things I still need help with are.. Is there a special tool to remove the lifter? do I need to use rtv or is the store bought gasket enough? And any tips would be greatly appreciated.

Post a video of the noise if you can. And I believe you need a ford lifter removal tool and a cam lock

 

that's what i'm worried about getting the truck apart and not having the correct tools to finish. I cant get a video up right now, ill try to explain. I first noticed the noise from the driverside tailpipe I was suspecting the cat. so I got a stethoscope and narrowed it down to the rear of the exhaust manifold.. fast rate tick, tick, tick. gets more dramatic under load. when I changed the oil the noise was audible from the wheel well. considering how much worse it got with the oil change I ruled out the spark plug, all tho i am going to check while back there and probably replace them. I just want to make sure I have all the correct tools before I jump in.

 

Are you 100% sure it's not an exhaust leak? Broken studs on the exhaust manifold is a common culprit

 

yea I dug into it today, all the studs are on the manifold. when I was looking for the leak I felt and listened around the manifold and downpipe. immediately after I changed the oil the noise increased 50%. Today I moved everything out of the way and when I went to remove the valve cover bolts it round off it was so corroded. I was so frustrated I took a break, its cold out there. what is the best method to remove these bolts. from inspection atleast 8 or so are in fair condition, looks like 3-4 may give me trouble.

 

What temperature are you working in?

 

it was about 30 today but windy. i only tried the one bolt, it stripped so easy its like i had the wrong socket on it. very rusted

 

should i try to grind a slot into it for a flat head screwdriver, drill it? this is new to me

 

Can you get at all the bolts with a grinder or air tool on each valve cover?

What about needle nose vise grips. They shouldn't be tight
