Corolla Sport 1.8L

I heard a ticking noise coming from the engine when i stepped on the gas. I took the car to the toyota dealer and he looked at it and called me back and said there was sludge in the engine and that i would need to replace the engine. i have been using synthetic oil in this car for over a year. I bought the extended warranty on the car when i bought it to cover the car for 6 years or 75,000 miles. the car was at 73,600 miles when the problem started. they would not fix the car on the warranty they said because it doesn't cover sludge so instead of paying the $50.00 deductible you will have to pay $4,550.00 for a new engine. they said if you want us to tear down the car and see if they will cover it we will do that but that would cost me $600.00 and they would probably still deny coverage. I think this is ridiculous, if you change your own oil in your car they won't cover the warranty. My brothers are mechanics why would i take it to toyota when i can have it done for free. I paid an extra $1,500.00 for a warranty on this car so my suggestion is put the $1,500.00 in the bank and let it draw interest instead of giving extra money to toyota to do nothing for you, so when your car brakes down you can use that money to fix it.
