Timing chains used to be only a few links long o
You can't compare the two. Theres a solid three or four feet of difference. Old timing chains were truly lifetime because they were so short.
1970's timing chains:
modern timing chains:
--> Humans are inherently unpredictable. You can scale components for predicted duty cycles across a broad range of driving styles and use cases, but there will always be outliers, extremes, and mishaps.
If someone is daily driving their car and using stopstart ten+ times a trip, two times a...
I can hear the sarcasm perfectly fine, thanks, lmao.
what's not lost on me is that you're genuinely suggesting that disabling stop/start under the pretense of minimizing wear on certain components is not a completely valid reason.
--> No its not. Wipers are a cheap inexpensive wear and tear item. Timing components are not. Even if its unlikely it will cause issues down the road, why even take the chance. You are wearing components more, period. Whether or not other things on the engine let go beforehand that make that...
You two are arguing different points.
You're correct that modern cars are designed with S/S in mind, and thus can handle it
GTB is correct that it is still better to avoid using it, as it is less wear and tear.
Now kiss and make up
I guess not? I dunno. I know next to nothing about modern hybrid systems. I cut my teeth on SAAB's and followed that shortly with old British and American cars.
I attended a few seminars on modern diagnostics, attended a few courses, but I never really had to use them since my work was rarely...
For what its worth, bearing wear/bad bearings are hardly what kills most engines nowadays. Its usually excessive cylinder bore wear, oil consumption, etc.
If your bearings are going, on most engines its due to an oiling issue, or driver error with over-revving when cold, etc.
Yeah. I try not to mogg on something just for the sake of mogging it, but I have opinions that I carry. I'd like to think they are, at the very least, somewhat reasonable.
I will say though, being told that its an EPA emissions thing, then sitting through a lecture being told that on BMW's the...
I'm quoting off of personal experience. Seen enough chain driven cars come in with timing issues for this exact reason.
The longer the chain, the more of a problem this will be. You don't see it in Toyota's since their chains are not typically a snake like that of the 4.2 found in Audi's.
If...
The biggest downside to stop/start is premature wear to the timing chain.
Timing chains rely on oil to keep all the links lubricated and from having the pins grind up against the links. Every time you stop the car, the links lose some of that oil and you get an absolutely microscopic and...
