Kim, Do you think you can substitue the cam cover gasket with silicone sealant?

The removal of the cam chain requires a complete disassembly of the entire top end. You will need a new cam cover gasket too. The shop manual is a must. Tip: if you decide to take this mission on make a cardboard pattern of the top end to keep your bolts in order. Just mark the outline of the cam layout, label the front and back, and push the bolts though the cardboard model in the places that they came off of the engine. Some of the bolts are different lengths and they should be placed back exactly where they came from. There is a precise method in which the internal bolts have to be put back on and a torque wrench will be necessary. I recommend that you read through the entire process in the shop manual before attempting this to make sure that you know what will be required and that you have the tools at hand to finish the job. I have cut my own cam cover gasket as well since they are expensive to buy. It takes time (and a leather punch) but it can be done. You will want to plasti-gauge your cams while they are out. That's where I'm at on mine right now. I've been sick so I've put it off and I had to get back on schedule with this thing. If you need any photos I can send them. HotrodMamma.

I took the valve cover off to see if I could see any way of getting to the tensioner but it looks like you have to take out the cam shaft(s), and whatever all. So, I think I'll just put the valve cover back on and pretend everything is okay!
