Default quick way to diagnose the hemi tick??

I have a 2016 Dodge 5.7 L hemi, I have 135,000 miles on it, I've noticed when it's cold it does tick and seems to pretty much stop after it's warmed up,
I did notice that there are broken studs in the exhaust manifold but is there a way for me to tell if perhaps the lifters are ticking also,?? If so is it cheaper to do a MDS cam or a cam delete, when replacing all the lifters?? Are there any great sources for a MDS delete kit??

If you have broken manifold bolts and the tick goes away when warm, you 100% have a manifold leak and your lifters are just fine.

You should be able to see some exhaust tracing, or on a cold motor spray the manifolds with soapy water then start the engine and look for bubbles, that's where your exhaust leak is coming from

Okay I can try that,,
PS I have 130 plus 1,000 on it and I just cut the oil filter open and inspected it really closely, the oil filter looks absolutely perfectly clean :-) I've had the car since a hundred thousand miles and I change the oil every 3,000 ever since then, it is a fleet vehicle and has 1/3 of its life idling
