I bought a 2010 SC Sport on an online auction last week. (sight unseen. 75000 miles). Same 5.0L engine as the L322. Unfortunately I have not even seen the car yet but my good wife has done me proud by recording the engine noise on her phone and has been through the fault codes with my iCarsoft i930. The codes are as expected but the engine is a little noisy. I did read up on the various forums and knew what I was getting into so no real surprises.
The first thing I did was buy a cam timing kit so when I do get home, I can start on whatever job I may need to start on.
Has anyone done a DIY on the timing chain/tensioner replacement? I have all the manuals (Topix), tools etc. to do the job but a bit of hands on advice is always useful. (I did search the forum but didn't see anything).
