What causes Low/No Compression in 2 cyl of 05 PT Cruiser?

Asked by Jun 19, 2015 at 08:38 AM about the 2005 Chrysler PT Cruiser Touring Convertible

Question type: Maintenance & Repair

Engine light came on, diagnosis said it was Air Control Valve.
Went to start the car, it sputtered and wouldn't turn over. Luckily there was a repair
shop next door, and they took her in.
They say it isn't the A/C Valve, but have no idea what is wrong.
Ran a compression test, 2 out of the 4 cylinders have 0 compression. Im thinking
timing belt/water pump?

It's a blow head gasket. Some people make the mistake thinking if it was a bad head gasket I would be getting anti- freeze in the oil. A head gasket not only separates the anti- freeze from the oil it also separates the cylinders compression from each other. Sounds like head gasket is blown between two cylinders causing compression mixing of the to cylinders.

A timing belt or water pump will not cause cylinders to loose compression.
