Civic DX Low compression in cylinder 4, what does it mean??
Well cylinder 1-3 rate in at 180 psi but cylinder 4 only has a compression level of 150??
What can this mean?? I know that rings may be a problem.

#4 piston is losing some compression. those results aren't that bad though.

Possibly a leak in the head gasket which causes coolant to flow into the combustion chamber.

Put a couple drops of oil in cyl. 4 and if the comp. goes up then your rings are probally worn.
