More oil confusion

[Zoe Saldana]

If that was the case every HEMI in -40 Canadian winters would have failures... lol...

We Idle more then anyone else. So saying idle is the issue is nonsense.

Its a combination of all the cheap garbage FCA puts in the HEMIs, there's a reason once you actually build your HEMI properly and tune it, issues goes away.

Idle time ..+. low oil pressure .+.. hydraulic valve wear = problems

I worked with a fellow about 38 years ago. In our conversations, he told me about his Dad who was an engineer for GM... Specifically, a "work cycle" testing engineer?? Product reliability? If I remember correctly. Anyhoo, this man's job was to do metallurgy, temperment, and such studies on axles, bearings, and so on.. (GM had it's own bearing company back then, NDH (New Departure Hyatt).

This man ran tests on items for how many rotations an axle, for example would turn before metal fatigue set it and the component failed. If it lasted TOO long, they changed specifications for the content or forging, or some element of manufacture to insure that it WOULD fail (planned obsolescence).

Fast forward to these here modern days. Domestic car makers no longer keep manufacture in house as was done yesteryear; thus, a global picture. I remember reading content origin labels on transmission overhaul kits which Ford provided me when I rebuilt Ford transmissions in the dealer. One kit would list 8 or more countries of origin for all the bits and pieces contained therein.

Where are Hemi camshafts made? How about the lifters? They might come from opposite sides of the globe! How difficult is product quality control to oversee in such diversified conditions? Obviously, in the big picture, cars and light trucks DO last FAR longer in both time and mileage these days as opposed to back then. When I first started in this trade, it was very common for me to do a valve job on then-current cars at 40,000 miles or less. Ditto for other major repairs.

Granted cars and trucks were only about 10% or so of today's prices, and the cost of living standards were much lower. (My parents' mortgage was $78.00 per month! Mom and Dad bought a new 1970 Pontiac Catalina with all the bells and whistles of that time for about $3600.00. )

When I observe the absolute brutality with which people drive their vehicles at very high speeds around this Houston, Texas metropolis, and consider the vast and drastic climate environs they operate in, I'm quite amazed at how much more reliable today's cars are. And yet, people expect so much out of their cars, do as little as possible to them in the way of PREVENTIVE maintenance, and want right now, CHEAP, repairs, and have the audacity to curse the maker of the car.... "What a piece of junk!", I've heard people call an otherwise dependable car just because they failed to, at MINIMUM, follow manufacturer's maintenance schedule.

These observations made, I pose this question: How many FCA RAM trucks with Hemis do just fine for a quarter of a million miles with no major problems? As opposed to the "Tick" or flat camshaft/ galled lifters? I'd love to be made aware of the true ratio of that statistic.

My customers drive Fords, Chevys, RAMS, Toyotas, Kias, etc. ALL have WAY beyond societal or insurance actuarial norms in terms of mileages. Several are past the 300K mile mark and still going great. The common denominator? Regular PREVENTIVE maintenance. Period!

I agree with this 100%!
