Neighbor has a Chevy Sierra with 105,000 miles and a burned valve. Says these days you can do a valve job and not do the bottom end. Years ago, that was death to the rings and bearings, but engines wouldn't go 200,000 in the '70s. Pretty much all burned oil by half that.
What do you think?

Do the heads, slap it back together. It works on Toyota's. Never done it on a Chevy.

"The Warden's" pickup finally started leaking a bit at around 170K - I'd just do the heads, and carry on. I have NO idea of how long these newer engines will last - but it seems to be a LONG time!
As it doesn't even spot the driveway - I just keep an eye on the oil level.

Yeah. Do the top end.
Notice that none of those engine machine shops are still open?
These new engines dont need an overhaul every 50,000 miles anymore.
Its actually been a long time since I have heard about a burnt valve......

Why is it that engines are lasting so much longer these days? Anyone know?

Actually, I think it is because of a lot of different things.
Better sealing materials, closer tolerances, better metallurgy, and what not.
Engines are better balanced.
They can keep tolerances so much tighter and uniform with computers.......never would have been able to dream of the consistency in the olden days.
At least on a mass produced scale.

Same reason 3000 mile oil changes are not done anymore.

^^^ This is the correct answer. I have a hard time believing "better fluids" has much to do with it.

So.,...any idea on what burned the valve? Is this a V8? Did it have the aluminum heads?
Never had an engine burn a valve on me. Did it run lean for some reason?
As and aside, we had a '70 Chevelle with the 350/300hp motor. Had to run 93 or better octane so it wouldn't ping. Used to be able to get Ammoco 101 at the pump. That car ran great. Sold it in the late 90's with 178,000 miles. It didn't burn a drop of oil, but dad and I changed it every 2000 miles since he got Rottela 30w for free. I really miss that car.
