Did i blowup my motor (
My 05 cobalt has no compression, I
couldn't even drive it up into the ramps
to work on it. It started being really
loud and struggling to get power when
you first took off down the road. Ran a
compression test, 3rd cylinder was
slightly lower than the others at
150/180. Just took a scan of it and its
saying the 02 sensor is bad along with
multiple misfires, and cooling fan not
running. When I opened up the hood I
was concerned how much everything
is coated in oil and what the bigger
issue might be to need these fixed.
Any ideas or advice is much
appreciated!
