Of course, now that you said this.....(lol!)1700 miles and still quiet

lol, yup. Especially he didnt knock wood....Of course, now that you said this.....(lol!)
In case someone new sees this, Corey is running 0w40 amsoil and it is keeping his tick away like redline 5w30.
What this means, his truck has always been a little more responsive at killing tick with viscosity instead of formula. Not saying formula wasnt part of it, but with his truck viscosity is part of it. Some trucks like mine the formula matters, 5w20 redline was just as good as 5w30 redline in my truck, but not Corey's. Corey's truck, so far 0w30 redline (old formula), 5w30 redline and now 0w40 amsoil have been the best??? 5w20 redline and amsoil lighter oils no good?? We will see how that does on piston slap, or are you changing the oil then? My guess that would be all bad news on piston slap level as amsoil 0w40 is way thick.
What this means on a forum level, clearly every truck and tick is different, what works for some wont work for others. But, it has been proven over and over a lubrication strategy often pays dividends at killing tick, so try something different if your truck is ticking, and consider formula and viscosity and find what works best. And when it comes time to buy a new truck, the one way to ensure you wont get hemi tick, don't buy a freak'n hemi.
r 4 and 5's now boke, damn guys I need a new pc.
Keep in mind this SS 0w40 is the SP formulation, the last time I tried SS it was the SN+. Not sure if it makes a difference or not but by 500 miles on the SN+ 5w30 my truck was ticking pretty bad. 1700 miles on this SP 0w40 and it's still whisper quiet.
Don't know what I'm going to do this winter yet, depending on the miles I have on this oil in October I might try SS 0w30 for the winter. Worst case I still have a ton of RL if that doesn't work.
Thought about that too....A good group III 0W-30 or 5W-30 with Lubegard additive, maybe?
best net book I had, a decade plus fo 136 bucks, samsung net book, sadly they don't make them like this now...Yeah - get rid of that Compaq.

This actual user experience shows just how marginal the Hemi lubrication system is.
Probly the ENIAC....Yeah - get rid of that Compaq.
I have been back in a Cummins almost three years, so testing my memory LOLlol, yup. Especially he didnt knock wood....
We had tj not have good success with this oil and weight, so long term will be telling. Since he went from redline to amsoil, we don't know if redline still have plating effect left behind. If he gets to a long interval and it is still quiet, it will be good info that this oil is another tool.
I believe TJ went from this oil which was ticking to redline which quieted his tuck. If tj is aound he can tell us the weights, I forget what weights ticked and which wee quiet on his hemi, now good info to add to hemi39.
lol, good ideaUsb keyboard
The 6.4's use piston squirters to combat piston crown heat,i've always wondered if the same squirter principle was applied to throw oil on the cam lobes would that make a differance in the life expectancy of the cam and rollers of the lifters. High idle time does seem to be a contributing factor to the cam/lifter issues,and using a squirter to throw more oil onto the lobes at low rpm sure couldn't hurt i'd think.
When they raised the cam tunnel to accomodate the VVt system,it seems to have affected the cam/lifters to,that little differance in height,means there's even less crank splash making it onto the lobes at idle. There's several contributing factors from poor angles on oil drainback,camshaft tunnels higher in the block,and poor quality construction materials etc.that all contribute to the lifter issues associated with the gen 3 hemi. Originally the engineers spec'd a billet cam for the engine,but the bean counters squashed that idea,so it makes you wonder if the engineers might have known something about the cam issueSure, but guess what, it costs extra (like MDS didn't ha ha). I suppose the 1st two generation Hemis had flat tappets? That certainly would explain why cams didn't wipe with the high ZDDP additized motor oils of their era.
But you sure don't want to starve a roller lifter's roller of oil - either the outer surface, or the inner bearing (not sure if inner roller bearings are different types). Rolling elements are sensitive to lubricant thickness compared to sliding surfaces.
Somebody was trying to explain the shallow oil drain angle of Hemi pushrods causes slower oil flow. All other variables being equal, that makes sense for a gravity drain system. So, perhaps the siamese valve system does require forced flow nozzles? Or solid lifters of yore (adjust valve lash, anyone? is there anyone left that knows how?)? Or better yet, overhead cams!!! Too late now, of course.
Apparently for the extra oil passage required for the cam phaser is my understanding.@Wild one - why did they have to raise the camshaft centerline to add a cam phaser to the end of the shaft? A Hemi camshaft is already raised to reach to the outer valve pushrod.
I've not worked on a VVT, so I don't know all the design parameters.
