There are 2 hoses going through the firewall from the engine, these are the coolant hoses to the heater core, one is 3/4" and one 5/8", the control valve should be in the larger line (3/4") which is the inlet, make sure that the valve has vacuum (heater on low), also check and see if both hoses get hot with the heater blower on low, if they do get hot your problem is not the heater control valve but the air temp control blend door actuator.

valve lifters make a kind of rattly knocking noise! which sort of follow engine revs.if they are gone you may need a new camshaft as well, best to do itr all at the same time and are sold as a kit.are you sure there is a new noise or are you just listening harder?

the problem is not the bcm. the passlock security sensor is in the cylinder and housing, if the cyl and or housing was replaced the system must be relearned. if you replace the bcm you still need to relearn the system or it still will not start.
