WHAT IS THE BAD TICKING SOUND WHEN FIRST STARTING FOR THE DAY IN THE ENGINE BLOCK AREA?

2000 GMC Jimmy • 215,000 miles

It seems to be ticking in the right side lifter area or under the thermostat on the block. Especially during a cold start. One guy I took it to said it was the camshaft (worn) and another said it was the lifters (probably worn).. Any other opinions or easier fixes?
