milky liquid in radiator.......unsure of severity.

I'm under the impression that milky water/coolant means the coolant seals are goin but i'm not sure. I searched for milky radiator and found nothing usefull but
i need to make sure what's going on.

as I said it is milky white water/coolant, which I assume are tiny little air bubbles. This car has never overheated as has a good 40-50K on the rebuild.............there is a chance that the coolant system needs a flush but i need some of your input on the subject.............

When was your last oil change? I drained a TII with a blown coolant seal and everything coming out of that was a foamy white oil.

sounds like coolant seals, my 90 gxl did that when the seals went, check your oil filler neck and see if theirs like a condinsation foamy film in it.

i had the same thing happen, only my coolant seals were fine. It was the freeze plug behind the front cover that was mixing the coolant with the oil.

well, here is an update:

the radiator was broken around the PAT.#............coolant was leaking from the edges...............I had a spare radiator and replaced the whole thing yesteday.........

I had a several issues during install ( I should know better than to overlook anything) but nothing serious.

I drove it last night with no issues.............but the coolant buzzer was going off a lot, especially at idle........it would go away under load ( i assume the sensor was not getting water at idle and the pressure of driving raised the water level).........

the radiator was leaking from the lower radiator hose and I tightened the clamp and added water...........that did not help at all, sO i came home for breakfast earlier and decided to double check the clam and it was not even on the hose......I took a risk, unclamed it and put it on the hose the correct way...........

what bothered me a bit was when I turned it on with the radiator cap off ( to top it off) and as I am pouring water in the radiator i saw bubbles........I know that's also a warning pointing towards the coolant seals but it was a fairly recent rebuild and has never been overheated....I will post any updates and please feel free to post any info, tips and suggestions.
