1981 Cadillac DeVille Coup 368 6.0 litre
An outstanding achievement for Cadillac in 1981
The valve train and most of the oil galleries were plugged with sludge due to failure to change the oil. 14 16 valve push rods needed to be replaced as they were plugged solid. All valve lifters were replaced as well along with the camshaft. Timing components such as timing chain and gears were also replaced.
The water pump and radiator was replace just as insurance.
The lower end (oil pan) was checked for damage and none was found. The main and rod bearings were like new with very little wear. The oil pickup screen was also replaced.
The headliner was replaced due to factory glue failure.
The 368 (8-6-4) is the last of the cast iron blocks Cadillac produced. With proper maintenance, this engine will last forever. Most people complain about being underpowered, and this is true. But, once you get this baby up to cruising speed, she'll shift into 4 cylinder operation and give you 23 MPG all day long.
Would you buy another car from this manufacturer? Yes
