yup it's the m104 in the smaller bore 2.8L. i'm not the original owner so can't tell how the car was cared for in its first half century (of k miles). i do have that golden brown varnish which is what i was trying to get rid of with the auto-rx " engine cleaner". it's still there as far as i can tell. i guess i'll just have to play this one by ear...
