Is my head gasket cracked?
It is totally possible. Combustion chambers are quite small and it doesn't take much fluid to fill one up. As the piston goes down during the intake cycle, a vacuum is created and anything in the intake will be sucked in. During the compression cycle, if fluid has been injected it has to go somewhere since it can't be compressed. A little bit of it will pass the piston rings, contaminating the oil, but it's a minor amount. After that there are two things that can happen: The head gasket will either rip allowing the piston to push the fluid out, or the piston rod will bend; often, both. You can see a bent piston rod: and a blown head gasket: An engine with a blown gasket will be able to turn when you crank it; if it can't turn or makes metallic noises, you have a bent piston.

2003 Hyundai Santa Fe will start then die. Then it will not start. After pumping the accelerator or holding on the floor and returning later it will start. Nothing codes out. This happens probably 15% of the time. Any ideas?

A friend has an older Miata that was improperly stored for at least three years. Most of the time, it was not garaged. The gas is old, the battery is dead, it has not been started. It was probably parked without an oil change. He is looking to do the minimum to get this sellable, so the primary concern is the initial startup and the brakes. What would be recommended , especially regarding that first engine startup?

I’ve asked a few mechanics and DIYers this question and so far no consensus. Let’s say you’re 1000 miles away from next SCHEDULED oil change, and you’re about to leave on a 2000 mile road trip. Would you choose to change your oil 1000 miles early before the trip, or 1000 miles late after the trip?
