Comp Cam/lifter failure
This means that since they sell in greater numbers, they will have more failures simply due to the sale numbers they have.
This is not excusing them. They make quality parts but some junk does slip through.
I bought a cam in 2018 that had jagged edges on several lobes like it was ground to spec but not checked for quality control.
In 2006 I had 2 of their XE285HL cams crap out.
The absolute best insurance you can have is GOOD oil. NO additives, just dedicated high performance oil. It has been reported that pour-in additives add nothing of value and can conflict with the additive components in the oil you're using.

Valvoline VR 1.
NO detergents either...I made the mistake of using this oil:
Synthetics are good, right? ZDDP too? It must be great oil.
Uhh, what is this?
The SN, SM and SL designation are HIGH detergent specs.
The oil had ZDDP but the detergent scrubbed it off the parts instead of letting it stay in place and protect the metal. This oil led to this:
10 lobes all failing at slightly different rates. No change in valve lash settings led to this. I ran VR 1 for years but switched to this oil in March 2021. I've driven about 1600 miles in that time and this happened.
What some people may not know is that Comp Cams has a little more than HALF of the Mopar camshaft and lifter market. They alone sell more cams than all other competitors combined.
