I did. In fact I have all service records for my hemi. It got whatever bulk oil was in the tanks at 5000km drains. As I've already posted it has over 270000 on the odo and doesn't consume a drop between changes,and will shred the tires at will.
So your entire comment is yesterday's news,as well as yesterday's way of thinking.
I used to be a thicker is better guy. I've been proven wrong,and I can accept that. You on the other hand seem to confuse the fact that thin oils are proving to take engines to higher mileages than ever before.
Use what the oem tells ya too.

" bulk oil " good luck. i buy my oil at advance auto, and hand that to my mech, to go in my truck. of course not all engine fails cant be explained. chaos theory is alive and well. and Murphy is still here.

I'm not sure what's up w/the Challenger chains, but this sorta thing can certainly happen. The good news is that you're less likely to need dental work when your car's timing chain bites it!


Was that chain maker Sachs, whose bike division was spun off to SRAM when ZF took over?

It just seems while a chain-drive system is reliable when it's properly engineered, it can fail if there's silly mistakes - like the Mercedes single-row chain. Of if a component wears down, again the Mercedes chain drive guide rails or the chain cover on a Toyota 20R/22R.

Oh man... first Pentastars, and now this!....They're all gonna blow.

In all seriously, I have not read of the issue in Ram forums.

In Germany the 15 degree VW VR6 has plenty of chain failures

The Mitsubishi 4B11T has chain problems during some years, I don't know if related GEMA engines do too.

The ford modular v8 absolutely does not have timing chain issues. Maybe guide or tensioner, but not the chain. Lets be honest, I probably have 300,000 miles in 92,95,98,00 and 04 panther body 4.6 fords. Not one timing chain issue for me or anyone in my agency despite very severe service.

The Audi 4.2L V8 (S4, S6, S8, etc) has a very small but still significant number of chain guide failures too. They had plastic guides that broke from fatigue; the part was eventually updated and the failures seem to be far less common.

When cams were finally available for 6.1's we had some timing chain failures due to the changes made. Different pulsations/vibrations wore the guides. But they were few and far between.

I have checked with my extremely reliable "insider" at Chrysler and he says that the nationwide failure numbers are extremely small. And he means ANY failure, not just timing chains.

Overall the new gen Hemi is an extremely reliable powerplant.

These types of failures always seem to be way more common than they are -- very vocally minority. No one ever posts about how their car is NOT having problems.
