I admitted defeat and took it to the shop. Cylinder number 3 has 50psi of compression, 1,2 and 4 have 150 psi. Currently, a bad valve is being blamed. Any other thoughts? Is this more likely than a cracked head or burned piston? The head gasket got replaced about a year or so ago, so it shouldn't be the culprit.
