The dimensional tolerance, metallurgy and surface finish was nothing like it is today.
Why do you think that cars use 0W20 oil today?
It's not just to reduce pumping losses.... 💡

Jim, I have seen a number of pictures of failed cams and lifters including roller lifters. The flat tappets I have seen show what is called "spalling" where the hard surface cracks and then essentially crumbles. Most of the lifters are being outsourced to China and I am sure if I could get one of the Chinese lifters and an older US made one (a) I would bet the US made would be a good alloy steel like 4340 and the Chinese will be a carbon steel (b) the Chinese lifters appear to be case hardened, and once the case hardened layer cracks it starts to flake off and the softer metal underneath just wears rapidly.

I'm not saying there isn't bad metallurgy.
But when you look at something like the old Chevy Berettas, you know, that those cams weren't made in China, and neither were the lifters....

Chevy V8s were bad about wiping lobes, usually an exhaust so the engine would pop back through the carburetor.

[ArdWrknTrk]

Strange things happen when the exhaust has nowhere to go, it's going to find some way out!

spent gasses seem to retain a little bit of pressure. it's not like it is bled off by the power stroke and a closed exhaust valve, even late opening is going to pop back. there are no points to assume are unimportant. the crown must fit the cam so that the driving surface of the cam is well offset to cause the lifter to rotate as it reciprocates. this rotation allows the cam to polish the lifter and vice versa. if not, then the cam wears a groove into the lifter face and creates a detent and it's all over from there. remember, the cam is rotating and using all of its surface against a spinning disc face. if not spinning then the contact point gets "ground" and super-heated.

[ArdWrknTrk]

This is why a really fubar cam chain spits back through the carb and can't get out of its own way
The charge has multiple times the amount of fuel it really wants, and the valves won't close in time to build decent compression.

My boss asked me to differentiate myself at the workplace

[essmaker]

Lol. And backed in like a boss!

[viven44]

Yes sir! Proud of the Bullnose! Gotta show it.

[ArdWrknTrk]

Always be ready for a quick escape!

How is it you can park wide open in the nether regions of something the size of Delaware, and when you hike back some (kind person!) 🙄
Has parked nose to nose...... and another so close you need a can opener to get in.

3 vehicles in a SEA of asphalt, and they need to mate with you?  😡💥

[viven44]

If I find a Tesla in a SEA of asphalt, I always park the 460 right next to it. Yin and Yang

[ArdWrknTrk]

Interesting, the dichotomy between you and me.

I don't know if I like you anymore.

You would definitely not be driving away from your space, and the engine might never turn again.  

[viven44]

Can I say 'I'm pleading the 5th' here ?

[ArdWrknTrk]

Come to CT.
Pull that stuff w/ me and I will split a quart of sulphuric acid drain cleaner between both tanks.
Then I will rip out all 4 of your valve stems with a big pair of side cutters.

There was a guy in the NMSH a while back, and he had "a smell" in his truck.
This isn't a decomp in a trunk ,  in  summer kinda situation, just "a bad smell"
This is difficult for me, because I need detail, to function.

We talked about things that smell gross, and how it happens
Three posts later his response was "remind me NEVER to (make you angry) 😳

Sometimes hard lessons are the best lessons.
You'd definitely never forget the ones I suggested to him.  🤣

[ArdWrknTrk]

I've decided.
THIS is why I want nothing to do with 60% of Americans under 45.

I can't go soon enough.

*Trim realization, that I edited into above post*

[viven44]

We don't want everyone to be boring. Just saying. You would be missed.

[ArdWrknTrk]

I'm not sure I reciprocate, at all

I'm stretched out here in a hallway well after midnight with another liter of IV saline and Keflex
I guess they want to make sure I'm well flushed???

[mat in tn]

I take it that the knee is not all better.

[ArdWrknTrk]

The necrotizing tissue in the joint I've been walking on for 22 years with a chowed meniscus and no labrum to support the mediai joint needs to be removed l

It just continues to rot in there, and this mans immune system can only do so much.

At least I'm in the right place (2nd largest Hospital in the US, behind Miami).
