Symptoms?
14
Low Engine Compression
15
Optimal compression is essential for smooth
engine operation.
16
In the case of a gasoline engine, it should stay
between 150 to 160 PSI.
17
However, a diesel engine somewhat needs more
compression (about 220 PSI) for a steady
combustion process.
18
If your Volvo XC90 engine is losing compression,
its engine block or head gasket might be leaking.

White Smoke Coming From Exhaust
20
This happens due to the leakage of coolant into
the combustion chamber of the engine.
21
So, if your Volvo XC90 is emitting dense white
exhaust fume, its head gasket or engine block is
leaking coolant.
22
This problem would worsen over time So, its
really necessary to identify and fix the problem
ASAP.

Oil And Coolant Discoloration

Oil and coolant can end up mixing if your Volvo
XC90 engine block has cracks.
25
Oil mixed with coolant will lose its lubrication
ability and would change its color to milky brown.
26
Similarly, coolant mixed with oil wont be able
to keep the engine temperature stable.
27
So, if your Volvo XC90 coolant or oil has changed
its color, it's an indication of a leaking engine
block.
