Ford Repair Questions? Ask a Mechanic for Answers ASAP
Ok, I remember you. give me a few minutes to review the previous thread to refresh my memory
Any thing is possible, it is also possible that because the tensioner was compressed during the repair and had no oil pressure in it upon the first few cranks of the engine after the repair that there was enough slack in the chain that it could have jumped a tooth before the tensioner had time to build pressure to hold the chain tight.
That ratcheting type noise you heard when you took the vct off was the chain sliding over the teeth on either the cam sprocket or the crank sprocket, I assume you had already marked the teeth to chain locations on both the cam and the crank sprockets?
If you lined it all up just the way you took it apart, then the only logical explanation is that it jumped time before the tensioner charged up. I wish I had an easy way to check it, but the only way you can, as I am sure you are aware is to take the cover off again. If it wasn't for the potential of the spark plugs breaking I would advise you to pull all the plugs and crank the engine over several times to charge the chain tensioner so the crankshaft has less turning resistance when and if you have to take the timing chain tensioner off again.
Ford dealers have a wedge on a thin steel handle that can be installed into the space between the timing chain to hold the chain in place for replacement of the vct sprocket without removing the front cover. If you get your crank mark on tdc, you will be able to (with this tool) move the sprocket by one tooth if you can tell that it is off by visually comparing it to the workshop manual.
Yes, you should be able to on the pull down menu when you ask a question.
