Yeah MQM, I got the whole kit from lcengineering, oil pump, water pump, timing cover, everything. I went alittle over board with everything. I ended up putting in a new radiator and distributor as well. I've got more money tied up in the front end than what the truck is worth! Not really, but close.
>>>*K....LC has a good kit, so that isn't the concern. It sounds like you have the torque down, we suggest 12 ft lbs for a maximum, we found that at 15 ft lbs the tiny little tensioner housing starts to distort and we get crabby emails about "defects" but you have it right, that isn't it.
The bolt groove in the passenger side guide is so it can be slightly adjusted in/out, some suppliers do the same to the driver's side guides on the 83-84 so the steel guide can be used, too short, trust me there...don't do that.
Chain breaks in upset conditions, then we get crabby phone calls....*LOL**...The chain can still break if it catches, the steel piece is stronger, not foolproof and yep it can be broken.
*I wish I had it in my hands, I could diagnose better, but the wear looks normal to me. Bolt a new set of guides on while you are in there, they are cheap...(Some suppliers hate me for saying that, about $35/pair for the duals)
My diagnosis? You are going to hate this: The noise is NOT from the chain assembly, check the oil pump gears to see if they are reversed, check to see if something is rubbing on the dampner outside, water pumnp? Maybe the clutch fan if equipped?
Long list of possibles. Put the chain back on and run her, looks OK to me.....*EB
