It is not good. Your head gasket has holes for the oil and water passages in the engine. You may have deprived your engine of oil or coolant and this may shortened the life of your engine.
Sure you can if you want to destroy the engine in the vehicle. I guarantee if it has a blown head gasket you will do some serious damage in 90 miles and possibly totally destroy this engine. I would not drive it 1 mile if it were my vehicle.
For each hour that you drive, you'll travel fifty-five miles. Lots of other things can happen, too.
it would taxi. (drive like a car.)
You should drain & replace your coolant at least once every 100,000 miles minimum.
It is not possible to repair the actual head gasket. Repair of a blown head gasket is to replace the gasket.
A head gasket does not wear out and there is no specific reason for replacing one unless it fails. Usually, head gasket failure is related to engine overheating that causes the heads to warp. Thank you, but it's not the head gasket that has broken. I had the seal replaced last year because it was cracked/leaking and leaking oil. And now the garage says it needs replacing again. Should it been leaking again so soon (after 13,000 miles)?
don't try it. i drove 20 miles without one and my head gasket blew. its a pressurized system and without the cap, there's no pressure. not a good thing.
You can drive up to 300 miles at that rate.
You drive 80 miles for each hour. So 80 * x = miles.
If you work five days a week, you will drive 235 miles a week.
50 minutes, if you have got a uniform speed, which usually doesn't happen...
It depends on the speed at which you drive. If you drive at a constant rate of 70 mph, you can drive 350 miles in 5 hours.
