This problem there talking about is for certain yrs or all 3.9 engines (cam chain failures )I have an 04 with 99.500 mi no noise ,runs like the devil is chasing her !Make sure you torque them like the manual says. I have reused those bolts on my four valve 5.4 rebuild. I am rebuilding a three valve at this time and will reuse those bolts as well.....
I'm almost positive just the 2002 model year, I've read that the secondary chain tensioners were updated starting with the 2003...I don't know about the primary chain tensioners.This problem there talking about is for certain yrs or all 3.9 engines (cam chain failures )I have an 04 with 99.500 mi no noise ,runs like the devil is chasing her !
Mine has not jumped...Basically just doing them while the covers are off...Another question, Do I need to rotate the engine to line those flats up anyway as to take spring pressure off of the cams? If so, I'm guessing by the crank bolt as everything is apart already.
Cam followers? I thought they looked like tappets...Ok I will keep an eye on them, I didn't know that they were at risk of being displaced when lifting the cam.Well .... I would rotate the engine to check the flats. You can then Zip tie the chains to the gears and then carefully back off the cam caps on each of the lower cams. You need to do that in order to get slack in the chain. That in turn will allow you to remove and replace the tensioner. Make sure the cam followers are in their respective locations and replace the caps. Start from the center and work your way out like a cinnamon bun. Do NOT tighten all the way just go a few turns at a time checking the cam followers as you go. You are putting pressure on the cam and opening valves. Take you time.
That was great Matt ,I have my 04 bird at ford now for leaks has 98.000 mi so I should get the tensioner done Correct ?Cam followers? I thought they looked like tappets...Ok I will keep an eye on them, I didn't know that they were at risk of being displaced when lifting the cam.
I would have them take a look at your tensioners...The problem with the secondary tensioners (exhaust camshaft chain) failing affected only the 2002 3.9L AJ30 V8 Ford and Lincoln engines, from what I've read...Your 04 3.9L AJ35 V8 should already have the updated secondary tensioners, which is easily identifiable by either watching the video posted by "The Flash" or the photo "Anthony C" posted above.That was great Matt ,I have my 04 bird at ford now for leaks has 98.000 mi so I should get the tensioner done Correct ?
