2001 toyota corolla S, theres a hole in cylinder #2 which is causing it to have no pressure and missfire. oil is leaking into the cylinder. do i need to replace the entire motor or is there another fix?

Re: 2001 toyota corolla, theres a hole in cylinder #2
You can have the engine rebuilt but the labor cost to do something like that isn't worth it. you can get a remanufactured engine with a better warranty for cheaper. you will also need to address the reason the piston burnt through, so it does happen on new motor.....remember to vote :)

To get to know about the displacement look at the engine codes which are printed along the engine number on the cylinder block, mostly seen from standing in front of the car with the hood opened. Some of the codes are described as under:
S.No. Model Displ. Year
1.1ZR-FE AURIS 1.6L 2007-11
2. 1ZR-FE COROLLA 1.6 2007-11
3. 1ZZ-FE Avensis 1.8L 2003-09
Cilica 1.8L 2000-03
Corolla 1.8L 2002-07
RAV-4 1.8L 2005-09
4. 2ZR-FE Yaris 1.8L 2007-11
5 2ZZ-GE Corolla 1.8L 2001-05
P0446 Evaporative Emission Control System Vent Control Malfunction Vacuum hose cracks, holed blocked, damaged or disconnected (1), (4), (5), (6) and (7) Open or short in vapor pressure sensor circuit Vapor pressure sensor Open or short in VSV circuit for vapor pressure sensor VSV for pressure switching valve for vapor pressure sensor Charcoal canister cracked, hole or damaged Fuel tank over fill check valve cracked damaged ECM
Use a cylinder leak down test. obviously a blown head gasket or valve intake or exhaust, just dont throw a cylinder head on it, especially #2. Why because the cause is a partial EGR system. When the system gets plugged the temperature of the cylinder head reaches it maximum. There it causes and advance and precombust on that cylinder head and BAM it goes either you have a hole in the block, or hole in the piston or kinder yet a burnt exhaust or burn intake. Heres the fix remove the cylinder head there you can inspect for damaged intake or exhaust valves clean it and look closely you will see crack, Then look at the piston carefully make sure there is not pits(small holes)
po171 is lean on bank 1--===causes --MAF/VAF sensors --injectors ---HO2S (heated oxygen sensor)
po300 is random misfires and po301, 2, 3 4 5 6 etc is the cylinder that is misfiring
most likely that the fuel pressure is below the required pressure either from the pump or blocked filter or the tank not venting properly--- (EVAP) problem
check the fuel pressure ( minimum of 45-65psi) --problem pressure regulator , pump or filter
replace the heated oxygen sensor on bank 1 ( in the exhaust manifold before the cat converter) as it reports to the ECM to get the correct air/fuel mix
Have the vehicle scanned for codes and do the repairs the codes reflect.
If there are no codes found then have a cylinder leakage test performed this way the techn. can determine if there are any vacuum leaks that are causing the miss.
If this turns out to be a-ok then the techn has to do a Injector balance test. might be an injector thats giving you a headache.
Check the master cylinder for oil. If oil got into the system then all the rubber parts have expanded and caused this condition. The other cause is that something is blocking the compensation vent hole inside the master cylinder. This hole allows for heated brake fluid to expand.
