Hello all, I have a quick question for any of you who have/had an 88 5ksq (2.3). Excluding a myriad of variables, is it "normal" to have a blown head gasket at 145k miles? We get the infamous cloud of white antifreeze smelling smoke out of the exhaust on my son's car. I'm hoping we didn't crack the block/head. TIA Regards, George Massachusetts 84ksq, 88 5ksq
