2002 Chrysler Sebring Q&A  2002 Chrysler Sebring Question:
Ticking noise in engine  My car makes the ticking noise when it
WARMS UP - NOT when it is cold. The timing chain was changed
because they were taking the engine apart to replace the water
pump, there is 54,000 miles on the car, and we thought we would
change the chain now as preventive work since it is recommended
to be done at 60,000 miles. It purred like a kitten before this.
Now they are telling me it is "scored rod bearings" not a loose
timing chain. We put in a heavier, synthetic oil, but still the
noise. Wouldn't the noise get worse as the engine is reved if it
was the rod bearings? And wouldn't it make the noise even when
the engine was cold if it was the rod bearings? Help! - Answer 1
The 2.7L engine is a very expensive engine to overhaul. Good
diagnostics as opposed to guess work is essential here. The
viscosity of the oil is thicker when cold, especially in the
north east. A Rod knock is a fairly heavy knock as opposed to a
tappet noise whic
