Q:
What will water in the engine block do to an engine? Will it damage it?
A:
in the cylinder bores?
if so, leave it long enough and they'll rust. water is used in the cooling system.
A:
Sorry I misunderstood your response. "Do you in the cylinder blocks?" I am not sure what that means.
I am asking cause my friend blew a head gasket and did not know it. There is water in the block and he is still driving it till he can get another ride
A:
cylinder bores. the cylinders, the "tubes" where the pistons live.
if he's got water getting in there the liners and possibly the pistons (if they're ferrous) will probably rust when the engine's not running. the other issue is this: if it's getting in the cylinders with the engine running steam will leave with the exhaust and he'll eventually run out of water/coolant and his engine will overheat. eventually it'll be (excuse the term..) fucked.
why's he running it like this until he gets another car? it's not hard/expensive to change a head gasket...
A:
more importantly, coolant (or water) and oil do not mix. When you have both in the crank case, and you run the engine, they turn to a goopy airated frothy mix that looks like.....mayo. (I was going to say another substance, but I'll skip that)
This substance does not lubricate an engine very well, and the bearings in the engine will suffer, quite severely, from prolonged running like that.
As usual, its a question of quanity. A couple tablespoons of coolant in the oil won't hurt anything. a couple quarts of coolant in the oil will cause the engine to seize in short order.
Driving the car like this, imo, is not only guarrenteeing the car is going to the junkyard, but it very well may leave him strandard in the very near future.
And thats not even touching on the car overheating badly.
A:
The antifreeze will attack the bearing surfaces. So I would only drive it if I was willing to accept that the engine will probably not be worth rebuilding after it quits.
