2000 Intrepid 2.7 timing chain

OK, so I get this 2000 Intrepid with a dead 2.7, pull the heads and all the intake valves are bent. I put the heads from another 2.7 with a blown rod on, buy a new timing chain, but when I try to line up the colored links with the crank/cam gears, I find out that there are two colored links right next to each other on the drivers side cam gear. So, I pick one of the colored links to line up with the marks on the cam gear, and now it won't start. It fires now and then but won't keep running. Is there another way to line up the timing chain so the valves open at the right time? Is there a way to check to see if the timing chain is lined up like it should be? Also, both engines were filled with what appeared to be burnt oil, not sludge, and the timing chain tensioner was stuck which I think caused the timing chain to skip and bend the valves. Both engines had the same burnt oil deposits everywhere and it seems to me that somewhere the aluminum block/heads are overheating the oil until it becomes hard and crumbly and blocks the oil passages. A lot of them are blowing up, they can't all be from poor maintenance. THANKS!

The deposits are a known problem with the 2.7l. One well known solution to the problem is to use Synthetic Oil, this keeps the deposits from forming. Synthetic can also lead to a failure if you change to it in a already gunked up used engine. It will start washing out the deposits and plugging things up. In this case, you would be in a no win situation, buy a 3.2/3.5l upgrade kit and a good used 3.2/3.5l and enjoy the reliability and power of the bigger engine.

Instead of the 3.2/3.5 upgrade kit,find a donor car that has been wrecked,cheaper.It is a whole lot easier and you have the parts on hand instead of going to an auto salvage yard for extra parts needed
