1992 TOYOTA CAMRY LE V6 154K NEEDS A NEW ENGINE INTERIOR IN EXCELLENT CONDITION

this is a 1994 toyota camry le v6 with 154,000 miles on it. i purchased this vehicle from my friend and drove it about 800 miles to chattanooga, tn where i was living at the time. upon arrival the car made a loud grinding sound from the engine compartment when i was about 5 miles from my house. i decided to have it towed to a mechanic and friend that worked on toyota's locally. after examining the car it was determined that the engine was shot due to sludge building up. apparently this is a common problem with toyota's with this engine. the mechanic told me that this engine will easily go 300,000 miles with a regular oil change but the trick is it cant be the cheap stuff. my friend had all the records of oil changes from 70,000 miles when his mom bought it but it was always walmarts special. i decided to replace the engine with a used one so i had the mechanic remove the engine. i have since ran out of money and need to get rid of the car. the transmission on the car has no problem and
