I have the opportunity to purchase a cheap Bluebird (Manual), in good condition except for a blown head gasket.
I need to phone the owner to find out exactly what he means by blown head gasket, but it may just be one cylinder...
How crazy would it be to drive this car home with a blown head gasket?. If I was lucky, and the head gasket was blown on one cylinder, then the usual risks would be:
(1) Water fills cylinder -> bent rod / crankshaft
(2) Water goes into cylinder and mixes with oil under pressure
(3) Water / oil mix directly.
If I was to ask the owner exactly what had happened with the car, and there is no sign of oil / water mixing, then why couldn't I just remove the spark plug for that cylinder, disconnect the fuel injector, clean around the spark plug hole, and duct-tape a sponge or something over the cylinder?. Then, any water leaking in (or oil leaking in), could just blow out of the top of the cylinder or down into the exhaust, you wouldn't get overheating from pressurising of the cooling system, etc?.
This is all hypothetical at the moment, but, if I could get 200 miles out of it (
), then I could get it from the South to North Island of New Zealand.
If I could then get another 400 miles out of it, I could get it home, but, once it is on the North Island, it will be covered by my breakdown cover; also if I destroy the engine, the manual gearbox would be perfect for swapping into my car, and the rest of the car could be broken for parts...
Any ideas? Is this madness? (if there are no signs of oil and water mixing, what is to stop me running on 3 cylinders thereby preventing water entering the oil down the side of the cylinder, and also preventing pressurisation of the cooling system?
