I took my 2005 Corolla in for service. I was noticing my temp gauge was running higher than normal. Toyota said that coolant is leaking into the engine, and that I require a new Short Engine Block. My car only has 140,000 km (87,000 miles.) Has anybody run across this problem. The dealership has quoted a repair for $5000CAD for a new block. So if anybody has some advise,PLEASE HELP.

This warranty covers repairs to powertrain components that are defective in material
or workmanship under normal use and maintenance.
Major Emission Control Components - 8 years or 130,000 km
This warranty covers repairs to specified major emission components that are

so your car is out of powertrain warranty, is ether fix it or use the 5k to buy used engine at junk yard or JDM engine, which might cost less I believe
This is the first I've heard of the engine block cracking.

There are several possible warning signs for a failing head gasket. Milky, frothy oil on the dipstick may mean you have coolant leaking into your oil pan. If one spark plug is much cleaner than the rest, you could have coolant leaking into that cylinder.
White exhaust smoke from a fully warmed up engine-- or sweet smelling steam coming out of your tailpipe could also indicate a coolant leak, as would a mysterious loss of coolant, with no visible dripping.
They failed to mention engine overheating, poor engine coolant condition (contamination), loss of compression in 1 or 2 cylinders (if 2 cylinders they'll be beside each other).
All these are the symptoms are of either a cracked block or a head gasket leak.
Did they take apart the engine and look at the block or are they just guessing...
Seeing that the original owner is from Canada, it's possible that a potential lack of cooling system maintenance allowed for a cooling system freeze, which could potentially crack a block. But it's exceedingly rare. Of course, casting problems could be present also, and also an extreme rarity.

I will definitely take it for a second opinion. However, they have not at this point taken the engine apart to see if that's actually the case. Sounds like this sort of thing doesn't happen too often.
Hopefully, they've at least LOOKED at the oil and found milky substance in there. It'd be a shame if they're just ASSUMING that coolant is leaking somewhere. Some questions for them:
1) How do they know that coolant is leaking into the oil?
2) Have they checked the thermostat for proper operation?
3) Have they checked the coolant temperature sensor for proper operation?
4) Has your coolant level dropped? Have you had to fill it recently? If not, I'm already suspect of their determination.
5) Have they done a compression test on each cylinder? That can indicate a head gasket problem.
6) Have they pressurized the cooling system to check for leaks? If the cooling system holds pressure, that'd be another reason to be suspect of their diagnosis.

utopka you mentioned that you took it in for service so I'm assuming a oil change was involved, or at the very least they checked the oil. They must have looked at the oil and found it milky...
A. If they didn't find milky oil: (I would flip my lid at this case) Check the cooling system for proper functioning as stated in JasonAs' post. Could be a coolant leak somewhere, a faulty coolant temp sensor or stuck closed thermostat.
B. If they did find milky oil: JasonAs' 5). A compression test is a good start, it will tell you if there is a leak in one (or more) of the cylinders. If there is a leak then unfortunately it's not going to tell you if its the block or the head gasket. The only real way you're going to narrow down the problem would be to remove the head and actually take a look at the head gasket and engine block.
A cracked engine block is more uncommon than a head gasket leak. But you know, strange things happen sometimes.
I want to add, that I have done all of my service at the same dealership. So its not like they have not seen my car ever. my last oil change was done July 1st.
So, I am still waiting to hear from Toyota Canada. It turns out that it is an external hairline fracture just below the head gasket. It's visible. I just took my vehicle in on Saturday as they wanted to take photographs of it to send to the head office. Therefore, still waiting. I got a second opinion (from a friend of mine) which confirmed Toyota's diagnosis. Toyota did pressurize the cooling system and that's how it lead them to the fracture. Anyway, will keep you posted.
Ive Saw one come through our dealer with a cracked block due to no coolant being in the engine itsself, was filled with water. Seeing you live in a cold area might be the case.
