What's needs replaced if you have a cracked block?

Question

I have a 2000 Civic si with a possible cracked block. What would needed replaced, specifics?

Thanks everyone for the responses! I don't have the car as of now, but I've been told the car is "spraying"/leaking antifreeze, and oil.

The car has alot of mods on it i.e. turbo, etc. The car only has 35k miles on it. I'm hoping it's not a cracked block.

Answer 1

If the engine block is cracked, the engine would need to be replaced. On that car, it is more likely that you have a blown head gasket or a cracked head than a cracked block. If you overheated the engine, the usual failure is in the head gasket or head. If you threw a piston rod, you could have damaged the block, but that should be very obvious from an external examination.

Why do you think it is a cracked block?

Answer 2

Verify you have a cracked block.

If you do, you have a few options - none cheap

1. Buy a used engine from a salvage yard and install it or have it installed

2. Look @ the availability of a short block (reconditioned engine block, crankshaft, cam shaft, pistons, connecting rods) from an auto parts store and have it installed

3. Look @ a long block (reconditioned engine block, crankshaft, cam shaft, pistons, connecting rods, bearings, seals) from an auto parts store and have it installed

4. Look @ a rebuilt engine including (reconditioned engine block, crankshaft, cam shaft, pistons, connecting rods, bearings, seals and external parts such as water pumps, etc)

5. Some engines are made with the cylinder walls so thin re-builders won't re-build them. If this ends up being the case, then your options are buy a new engine or option 1 ( a used engine)

Your final decision should be based on total cost (parts and labour) vs risk of using a used engine

In the Southeastern US, a 2000 Civic Si in running order w/80K miles wholesales between $6000 and $8000 depending on amount of reconditioning which needs to be done to get the car sold

Answer 3

The "block" is the main body of your engine. It's more common to have a cracked head than a cracked block, but if indeed you have a cracked block, it usually means it's time for a changeover engine. Because the block is the 'core' of the engine, you basically would have to dismantle virtually everything to get to it and replace it. Because of the cost of labour, it may well be more cost-effective to find a replacement ("changeover") unit that can be swapped in with all it's big end, pistons, rings, already installed.

Answer 4

The block. The best thing to do is buy a rebuilt long block. You would then have to take all of the parts, which are bolted onto the engine, from the old engine and attach to the new. They would be exhaust header, intake header, water pump, alternator and so on. The total cost could be as much as $4,000. Is your vehicle worth that much.

Answer 5

If the block is cracked, then the options are a new engine, or a new car.

Answer 6

not enuf info. Need to know what the motor is doing. Leaking coolant? Oil? Overheats? If its blowing oil you might have to replace the engine or half block. Just not enuf info from you!!!!!!

Answer 7

The block is the lower part of the motor so I say if its cracked replace the whole car. It will be cheaper than trying to fix the one you have.

Answer 8

Although it is occasionally possible to repair a cracked block, usually you have to simply replace the motor.

Answer 9

if the crack is noticable and can be gotten to, then you can have a sheetmetal shop drlll a hole at each end of the crack and heliarc the crack.......good luck
