Is the bottom end damaged

Asked by Aug 21, 2014 at 04:09 AM about the 2001 Chevrolet Cavalier Base

Question type: Maintenance & Repair

I have a 2001 CNG cavalier.  Gauge started showing low coolant at about 150K mi. Impossible to find leak  So just kept adding water.  At 160K after 15 mi trip the engine shut down after the y gave out..  Looks like no compression in cylinders.  The CNG cavs have a plastic y in heater hose lines that feed the CNG tank heater and they deteriorate with age so if you have a CNG cav with slow leak    STOP!  REPLACE THE Y'S in the heater lines.  My question is can I expect any major damage to the bottom end or can I just get another head and do a valve grind on it?

1 Answer


No compression can also mean ring or piston damage, I have also seen engine blocks turn blue from too much heat, the only way to answer is tear it down, see if there is more damage, or do a cost comparison, of repairs to engine replacement. There is no real good answer this early into the repairs.
