Wonder, it's not leaking methanol past the rings, it's the effect from the high latent heat of evaporation of the methanol lowering the temperature of the engine below the dew point of the air being pulled into the intake port, thus condensing water inside the engine WHILE IT RUNS!
"Some" components? There is NOT A SINGLE manufacturer of electronic fuel injectors on the face of the planet who will warranty ANY of their products for constant contact with methanol. I'm looking forward to seeing your design.
Compression ratio can be increased to the neighborhood of 14:1 with streetable camshaft grinds in normally aspirated engines, but normally aspirated engines cannot take full advantage of the latent heat of evaporation of methanol. However, super/turbocharged engines can operate reliably with compressions of 10:1 and intake pressures of 20+psi gauge without aftercooling the inlet compressor system. That sounds good too, but not many people want to live with such a device for daily transportation, and even fewer could control it.
If it's getting into the oil (as you say previously), then it's leaking past the rings. That's the only route by which it can get there. I'd like to know exactly what kind of engine you purport to be running--it certainly doesn't sound like a car engine.

I was referring to carbureted engines. All the past experimental work on methanol engines has used those. CERTAINLY in a fuel-injected engine, the injectors would have to be specifically designed for methanol contact--a relatively trivial task. Methanol is NOT hydrochloric acid.
