If you are wondering why this is good news ,it is because if the timing chain is not the source of my engine noise, then it is probably a much more serious problem like a rod knocking. The tensioners appeared to be all the way extended but still could not keep the chain tight because I could take my fingers and tap the chain and it would slap against the guide and make quite a loud noise. The chain had worn all the way through the nylon on the guide and all the way through the aluminum too and had started wearing off the top of the tensioner piston. I sure hope this fixes the problem because I decided that while I had it apart I would put new spark plugs, coil packs, radiator hoses, belt, belt tensioner and idler pully and new anti freeze and thermostat. I could end up with a bad engine with a lot of new parts bolted to the front of it.
