Coolant Flush Findings

[Boostin18]

I flushed my coolant on my 1990 GSX with 60,000 miles. The initial drain there was all coolant with a hint of brown (oil?) or could be just a hint of dirt (this is what my buddy thinks) The next 4 gallons of disstilled water came through the system dirty, but with every gallon the it seemed like the water was coming out the same, with either dirt or oil. The last two gallons it seemed to be clearing up. Now when my buddy was pouring the water in, he said he saw something brown rushing into the water he was pouring, but when i looked it either looked brown or like a million tiny bubbles rushing up. It seems to me that there is oil in the coolant, but if anyone has any ideas, let me know. Now the brown portion in the coolant was very minimal, so very hard to tell if there is oil, but if you look at it you can tell that it is either oil or just dirty. Thanx in advance for the help!

It could be dirt but check the oil for water, pull the vc and look for traces of condesation on the inside of it, and do a compression test. If every thing else is good, I would say it was just dirt, rust, and trash mixed.

I just flushed mine. It was the nastiest stuff on earth in there. I know my head gasket is going, so I think I had some oil in there. But mine had little clumps of dirt in it. I guess its something that should be done more than once everyother year or so....

I did compression today and it was 160 across the board.

Brown stuff is rust deposits Dont worry

Yeah i think after the compression it made me feel better, when i picked up the car the guys was more than a quart of oil low, and it was white smoking bad, but i did an oil change and it stopped. So all these factors were making me think head gasket, but it turns out and thank god that it was just mistreatment of a DSM. Thanx to everyone who helped out and gave info.
