Hogger - are we talking about just replacing the timing chain? Breaking the old chain and using it to feed the new chain thru? Or are we talking about replacing the tensioner along with the chain? And if we're replacing the tensioner too, does that mean I'm taking off the front engine cover?
I'm also interested in any DIY procedure, along with torque values. I'm going to review Hogger's thread too.
Thnaks for posting part #'s Blashbenz!
Blashbenz - I got the valve cover gasket from a dealer, and it included the spark plug gaskets. Good idea the change them anyways, they have a bad tendancy to leak. Don't know the part number, but order a new tensioner plug/seal. Like I said above, you'll destroy the old one getting it out.
I ended up rolling the chain so the master link was on the top of one of the sporckets, so there is some support instead of sitting between the sprockets.
I used a chain breaker with a bolt in the opposite end, and a little divot drilled out just deep enough for the pin on the back side. This way I could keep the force as evenly distributed as possible. I was able to hammer the end of the pins pretty evenly without a tight link.
It's a little tricky because too much and you stiffen the link which could snap it. And too loose, the link could fall apart.
Not saying this is the right way, but that's how I did it.
