Oil on all 6 spark plugs, and antifreeze in clylinder #6
I have a 1998 Honda Passport with 183000 miles the check engine light came on my husband got the code out and it was a misfire cylinder #6. He pulled the spark plug and there was oil all over it. He changed the coil pack. The car recently over heated and there was no anitfreeze in it. He decided that he should change all the plugs and now there is antifreeze in cylinder #6. Could this be a head gasget, valve cover seal? Is it worth fixing?
