Hey, I quess I'm joining the mystery dissappearing coolant club. With half a brain can I replace these gaskets in my garage? Think I drove it 4 days when I found the coolant was going into the oil, parked it. since the daughter is 15, I would have a year to fix it, me and my son might spend that year doing the thing in the garage? any tips? since I'm that far do this too? I got , I think,, good pictures and instructions from autozone.com, need all new head bolts? Do those pour this stuff in the oil to fix coolants leaks work?? With 145,000 miles should I just replace? Was maintained by me since 81,000, ran great, all the time. Any advice is needed. thanks.
