Automobiles Aren’t Submarines, But Car Engines Can Survive Some Water

Unless you own an amphibious vehicle your car has no business being in more water than a puddle. Unfortunately, this can’t always be helped as accidents and natural disasters sometimes occur. The question is, what do you do with a car after it has been submerged in a lake or caught in a flood?

If you see blue smoke coming out from the engine, you have another problem – you need to change the valve seals. This is a more experienced step and I would recommend you take your … Continue reading >>>>
