Can a leaking intake gasket cause coolant to get inside the engine?

Many US and foreign car makers use engine coolant to heat the intake manifold for a smoother running and leaner burning engine. Without knowing the exact make and model, AND the size of the engine, it's impossible to say whether you have one of these water heated intake systems. I am assuming that you are talking about the intake manifold when you say "leaking intake gasket." The system is very popular, and normally reliable. It's not very often that the gasket will just simply begin leaking; but, if it does, then intake vacuum will work together with cooling system pressure (up to 17 pounds) to syphon coolant into the combustion chambers. You can sometimes prove this is the problem by removing and checking the spark plugs. IF I remember correctly, they will have a built up residue, but I don't remember off-hand what color it would be. Sometimes, if the leak is bad enough, soon after starting the engine you can smell ethelyn glycol (coolant) at the end of the tail pipe. DON"T take more than a couple slight wiffs; carbon monoxide is a serious killer and you won't get away with just standing there breathing the stuff; be careful.

Can the head gasket blow and leak coolant inside the engine because the vehicle overheated?
Yes it can. check the oil dip stick. if coolant is leaking inside the engine the oil will be "milky" in color.
If not the head gasket how is water getting into the oil?
Intake gasket leaking on the inside of engine.
What can a head gasket do?
Head Gaskets are a seal between the engine block and cylinder heads. It keeps oil, coolant, and pressure inside the engine. Usually if its "blown" the car cannot be driven due to lack of pressure in the cylinders. Smaller problems like a cracked or leaking gasket will be noticed by overheating, leaking of fluids and mild to severe decrease in engine performance. Since it is inside the engine usually replacing one involves removing the engine. Cost for repairs can run from $500 to about $2300
Where is coolant reservoir on a 1992 Lexus ES300?
Coolant reservoir, or directly in the radiator. If you are having to add much coolant, you need to find out why. Serious engine damage can occur if it is leaking inside the engine.
If the heater core is not replaced can it cause damage?
If your heater core is LEAKING engine coolant so that your engine coolant level drops too low or the engine coolant is lost completely and causes your engine to overheat then your engine can be damaged beside the mess the leaking coolant makes inside your vehicle ( you might be able to just temporarily bypass the heater core so that no engine coolant is flowing through the heater core )
What would cause a 1989 sunbird 2.0lL K engine to a have coolant leak coming from drain plug in firewall Not leaking inside coolant coming from rubber elbow connected through firewall?
If it's leaking from INSIDE the firewall (away from the engine compartment) you probably have a leaking heater control valve or damaged heater core.
What does it mean when you have fluid inside your spark plug holes?
Depending on the engine, it could be a leaking valve cover or head gasket.
Will a leaking lower intake manifold gasket ruin a engine?
It is possible if the leak is a "internal leak" - where the coolant is leaking inside the motor and mixing with the oil it will ruin the motor. This will eventually cause bearing failure. If it is an external leak - as long as you keep the coolant full and watch your temp gauge, you can get by for a while. Keep in mind - the leak will only get worse as time goes on.
Is it safe to drive a car when the coolant tube is leaking inside?
No , this coolant is coming from your heater core and you are losing engine coolant ; you need to have this repaired because the engine will overheat and suffer damage that will be more expensive than the repair of the heater core .
What causes coolant to boil and overflow?
Engine coolant temperature is cooled by the radiator, moved by a water pump and controlled by a thermostat. If there are troubles with any of those components the coolant will boil Also if the head gasket goes bad gasses from combustion inside the engine will get into the coolant and cause it to boil.
What causes white smoke from coming from inside the car engine?
White smoke is usually vaporized coolant. You may have a blown gasket or a crack somewhere.
What are the symptoms of blown head gasket or cracked block?
There are many different ways a head gasket can "blow". i just replaced one that was haping serious problems. in most cases you will expereince some kind of over-heating and extremely poor engine function. in my case my oil level was fine, but the gasket had ruptured next to the edge of a cylinder and was leaking coolant into the cylinder. this cylinder and everntual another failed to fire correcting and eventualy the engine wouldn't even start. coolant was visible coming out of the exhaust pipe in significant amounts. sometimes the same thing will occur only instead of coolant it will be oil leakin ing. sometimes when a gasket is blown oild can visibly be seen leaking in large amounts out from where the block meets the head and down the block. run through your engine systems and make a check list. check each and every engine system and cross them off. when everything else is fine then begin checking your main engine parts. a blown head gasket can cause many different symptoms. If your block is cracked, more then likely this leads to catostrophic engine failure. you can visibly see a break or crack in the engine block and oil and/or coolant can be seen leaking in large amounts. Whoever wrote the first part of this didn't mention that your engine can have a crack in the cylinder wall inside the engine and coolant will leak from the water jacket into the oil and oil into the coolant. And if the crack is in the cylinder wall you won't be able to see the crack and the oil and coolant won't leak onto the ground; but when you check your oil or coolant you will be able to see the two mixing.
