Cylinder misfire

Asked by Jun 17, 2017 at 04:06 PM about the 2002 Jeep Liberty Limited 4WD

Question type: Maintenance & Repair

2002 liberty 3.7- started with coolant coming out
the overflow (looked like insulation foam). Had head
gaskets checked- was told they were okay.
Changed reservoir- all was good. Then radiator
sprung a leak- cylinders 5 & 6 misfired. Fixed
radiator leak- changed coils 5 & 6. All was good
about a week- cylinder 5 & 6 misfiring again- pulled
plugs- antifreeze in coil number 6. Thoughts? Was
the head gasket test wrong?

If the coolant looks like a brownish foam you are getting engine oil in the cooling system. Probably a bad head gasket but it could be cracked head.

I am losing antifreeze- no apparent leaks. I am not losing oil.
