Thanks to all of you for your very valuable responses!
I have checked under the oil cap and saw nothing like a cross contination sign.
It sounds like I do have a little time to drive it like this from yr input
head gasket was replaced @ 60k
radiator was replaced @ 63k 84k 136k 3 times!
I will do a compression test this weekend
and also check radiator, drain oil and trans oil to see what else I can find
let me know of any more ideas or advice
thks!
