How many miles is too much for chassis?

[Mishakol129]

I've got 350,000 miles on my 91' wagon chassis and did an engine overhaul recently (10,000 miles ago), was this a bad idea? The chassis looks to be in good condition, little to no rust, everything is solid, and it is a great ride. Just wanna know how many miles is too many. I wanna know because in case I want to swap like an H22 in it in the future or just get rid of it.

No such thing. The more miles, the better. It's good for bragging rights.

Joe did a million miles . . . .

So long as the chassis isn't rotting then it should last forever.
This isnt Gran Turismo where you have to overhaul the chassis to get it's strength back.

I have 292,000 miles on my 4 year old Fit. 350,000 for a 22 year old Honda is nothing as long as it's been maintained (or restored.)

haha yeah, bragging rights. But I want to know about rust, what is it that causes it and what prevents it. Like I don't wanna have my gas tank rust through. I had some rust on my paint job cause it was peeling so used to rustoleum.

Maybe I should do an undercarriage inspection for rust and other things. It looks like a protective covering of dirt has coated the entire undercarriage keeping it from rust.

Its puzzling why some cars get rust while others do not.

The cars that are most plagued by rust are in areas where they use salt on the roads during winter. I'm in NJ, where they always use salt. My CB is rusted. My Fit is already starting to rust.

I think a larger determining factor there is how the owner takes car of the car. Whether or not they drive it in the rain, snow and salt, or drive a different car on those days. Also if they keep up with car washes to remove salt and dirt stuck on that can accelerate rusting.

Even where a car is parked can affect rusting. Parking on hard pavement versus grass, or gravel will all have a different effect on how the moisture will stick to the car and cause more rust.
