Any help please? Thanks...

Well the signs of my failing head gasket95 4runner 3.0) were: loosing coolant slowly having to top off each week, and no visible exterior leaks, tempature rising toward the RED when driven some distance, until the thermostat opened up and allowed the cooled fluid in the radiator to circulate thus bringing down the temp.Turning the heat on with blower on high would help also.
The 4runner did get worse over a few weeks, started to blow White smoke out the exhaust and missing on a drive home from work 25 miles and I made it home
My vin number ddin't qualify for the massave recall, and I had 187,000 miles on the clock at the time she blew.If I were you I would go rent a pressure tester, warm up the engine to operating temp then remove the plugs and do the test.I would bet your problem is in the #6 cylinder
you could also pull your plugs and read them, they can tell you a lot about your combuation
I have a link to my head gasket repair if you need it, if that's your problem
here is a video of what my exhaust when the head gasket blew, hope this helps..btw this was in the summer so that is humid white smoke out the exhaust
