Yeah, I think there is a large market for anyone willing to make car parts for things that sound like problems but really aren’t. Rake that cash in.
Than I assume that all modification or improvements to all cars / trucks / jeeps is a wast of time and not necessary. I assume that the engineers got it all right the fist time like the Boeing 737.
Properly operating lash adjusters, like old-school lifters, should self-adjust after just 1 or 2 "cycles", meaning 2 to 4 revolutions of the crankshaft. At 3,000 rpm, that's 50 revolutions every second - it should be less than 1 second to self-adjust.
Oh, so that's what he was saying - everything is perfect and ALL mods are totally unnecessary.
Yeah, at this point there’s not much I can do about the clatter at 2k RPM. It hasn’t seemed to get worse, so just going to turn up the radio. I put this one up there with my 1st to 2nd shift squeal that seems to be common with the ZF 8 speed. I’ve had 3 and all 3 have done it. Worst case, it’s replacing an expensive component.We've owned 5 Pentastar 3.6 2nd gen (PUG) equipped Jeeps.
None have ever had any "rattle" at start-up.

If you change oil viscosity by much you can make this a lot worse. you can also make the transition between valve lift stages rattle because the oil isn't flowing fast enough. Flow rate matters with these. There's a high volume pump for a reason.
When you start these engines, the oil pump is in high volume mode - oil pressure builds FAST. It jumps up to about 70 psi within a couple of seconds, then drops back to low volume mode. It does this to fill everything near instantly upon startup (cold or hot start)
Running heavy oil and cold temps may make the owner/driver feel good, but really does the engine no favors (and so far no one has any proof it's helping anything but make them feel better.
Oh, so that's what he was saying - everything is perfect and ALL mods are totally unnecessary.
I took if that most of the time, they are simply owner preferred changes,, and often a placebo or feel good, while some are actually improvements.
But if he was saying ALL are unnecessary because everything is perfect, that's different.
Seems that Boeing thing keeps being brought up. How about a new one?
Not what I said. But I could be clearer, so I’ll do that.
Simple test.
I’m aware. On the surface this seems like an awful thing. But it’s not.Simple test.
I think this one falls somewhere in the middle. Are there millions of pentastars on the road with the OEM filter and driving hundreds of thousand miles… of course. Is the Baxter system snake oil… not by the definition. It likely provides a bit more start up protection, but referring back to point one it’s likely not necessary. Point 3 though is my warm fuzz feeling not hearing a coffee can full of nuts and bolts falling down a staircase every time I start it up now. I swear my engine is happier and says thank you to me every time I start it now.
I agree. No more rattle rattle on both my Wranglers.
On some old engines, the oil drained from the end(s) of the head(s). Best example I can think of off the top of my head is the 426 Hemi. When Chrysler designed the heads, and adapted the 426 wedge block to use them, they put the oil drains at the front and rear ends of the heads and block.
What I found on my first oil change surprised me.
