@ CunningStunt ,
I can't believe no one has responded to your post , so I'll try to answer your questions ....but first I have a question for you Sir ...
You said you've had 4ea oil changes and you are approching 100,000 miles ...??
Did you purchase this truck new or used ?
If new ....what oil have you been using with such HIGH oil change intervals ???
If used , how many miles on the engine when you purchased ?
NowI'll try to answer your questions ...[emoji16]
First off a ticking noise is NOT normal unless you are hearing the fuel injectors ...you may be hearing an exhaust leak ??? Many here and abroad have had broken exhaust manifold bolts ...
IMHO ....you should not be using a 20wt oil in your hemi 5.7L 395 HP Engine , a 20wt oil is for a 4cylinder engine ....the 20 wt oil is an ignorant government fuel saving standard impossed on vehicle manufacturers ( has nothing to do with protection for your engine )
I'm the guy who is running a 50/50 mix of Redline 10W & 5W DASH - 30 OIL ....this is for higher Molybdenum , Zinc and Phophorus ppms in these two oils , and the 10W I believe has the higher Molybdenum, zinc & phophorus.... I'll be doing a UOA aka Used Oil Analysis soon to verify these claims I've read on the 10W Redline .
I and many others believe the higher ppm s of Molybdenum , phophorus and zinc is the best mixture for the 5.7L hemi ....modern oil regulations ( cafe ) have lower phophorus & zinc )
As for the type of RP Filter we are using :::
RP 10-48
Or
RP 20-820
The 20-820 is the larger of the two and fits just fine on the 2013 - 2018 Ram trucks .
Hope this helps !!
