Replaced the secondary timing chains and tensioners, along with a bunch of other parts (water pump, primary chain guides/tensioner, drive belt, idler, and tensioner) while I had it apart just in case. Finished putting everything back together the other day, started it up, and proceeded to freak out because it ran like [censored] and stalled repeatedly until I realized I left the MAF unplugged. Now it purrs like a kitten and didn't blow up!
Supposedly they came out with new parts in 2010-ish that don't eat themselves anymore which is awesome because I do not look forward to ever doing this again. Took me at least 20 hours over 2+ weeks but probably saved me $2,000. Hardest part was scraping the old RTV off the timing cover and getting it back into position without messing up the fresh new bead. So far no leaks, though.
