I have an old Mitsu Mirage (1992 with 141,000 miles)that has been recently diagnosed with a leaking head gasket. I do not think that the coolant is leaking into the oil (and vice versa) and do not think this is a new thing (I suspect it has been leaking for awhile, there are also numerous oil leaks). I do 3,000 OCIs with dyno and have done a ARX cycle.
I am not going to spend $1,400 for the head job and associated fixes, so at this point I wonder if there is an oil or additive that anyone believe helps to extend the life of the head? I have done 3,000 OCIs for years on this car (I think the reason it is still running) and it still runs fine. I have used Lucas in the oil in the past (not recently) and wonder if there is a type of oil or additive that would help. I has used cheap 10W30 for years that seems to work just fine (Supertech and Havoline).
Thanks to all for this great board......
