Same here.
All the stuff I've seen engines go threw and live, the last thing you have to sweat is some mircoscopic zinc level or lack of lead.
Ya know a 350 Buick can run 15 miles with ZERO oil pressure at 240 degree at 100+ mph rapping and ticking the whole way? Stop in a convienence store at 3am grab some el cheapo no name oil, pour two in, find nothing on the stick..... go buy two more.... now you're a half a qt low. He fires the mill and it's ticking, which PO's him VERY much. So he starts burying the tach off 7 grand till only one or two of the lifters still tick. Then you suggest he buys a qt of trans fluid (no MMO, Risolone or any other snake oil), dump it in and Wha La, quiet as a Caddy-a-lack. Do this to the mill a dozen of more times at seperate occasions and it's still alive years and years and dif chassis' later.
Then I have many story's on cam break-ins that people wouldn't believe, yet they never ate a lobe.

Just a quick clarification. Benzene is a component of gasoline (typically 1-2%). I think you're confusing benzene with MTBE which was added as an oxygenate at various percentages (even seasonally) to satisfy emissions and octane requirements.
I think I just bored myself to sleep....

Just to clarify, the seats in a 1972 would not have been induction hardened. I believe the valve seat recession occurs at engine output, I can't imagine it being a problem. |

Interesting since the other companies were doing induction hardening on some engines for years by that time. (I've got a book on engine top-end building, and it talks quite a bit about that topic)
So why AMC didn't? The book was published in the early 70s and covers the 1960s and first couple of years of the 70s. I'd just run it, too. When I was on the farm in the 80s, we bought an actual lead substitute. It was NOT an octane booster, was purely for valves and seats and did nothing to "boost" octane. I doubt you will find it on the auto parts stores or walmart. I might still have some left as I stopped using it after a while. |

Look at the contents if yo can find a bottle. They usually containe MMT which is now used as an octane booster. Also I have yet to hear of a manufacterer who wasn't induction hardenning by the early seventies. The auto companies knew about the coming low lead and no lead and prepared for it in advance. This started well in advance of the shift to unleaded because they had to warranty these things. This is also why they shifted to sodium filled valves in the heavy duty engines early on in the pollution days. They were getting ready for the higher temps and lean mixtures. If you were going to make a product today that you knew would be operated in vastly different conditions next week and you had to warranty it, Wouln't you think ahead. Even if it was just to keep your reputation?

Benzene was used to boost octane to limit engine knock in gasoline before WWII (and no, I don't remember that far back). LOL. It was one of those little pearls of useless info a chemistry professor I had used to toss out to us. Weird thing is, I remember that stuff better than the chemistry part.
