I'll have to do a timing chain as well, hopefully before winter. When i checked out prices for the kit, they were reasonable, the 3 piece was $25, and the others ranged up to $75. According to the manuals I have, it doesn't look like too difficult a job. You don't half to get into the valve's, it's all on the front of the engine. Pull the radiator and fan, remove pulleys and then the timing cover (mine is a 2.5L) Biggest thing I'll need to get is the time to actually do it.
