HELP! White Gunk in Coolant tank.

[Isosunrise91]

I could not tell you off hand. I had an Indy do all the work. They stressed how many time’s they had to flush lines because of the initial oil contamination from the bad oil filter house gasket leak.. to put it into perspective my belt was soaked in oil too.. was a long time coming from previous owner I jus trust have missed it. Frankly I can’t imagine anyone using numerous gallons of distilled water by hand to flush.. wouldn’t be shocked if at first it was regular water..

Any suggestions? Car runs decent. No change in behavior

How did they flush the cooling system? Oil contamination has to be flushed with a degreaser, otherwise oil will stick to the walls and won't flush out. Are you sure this is not oil? I would start the car with the coolant tank off and wait for coolant to reach 100F+ to see if the gunk melts. Then I would add some coolant to overfill the tank and see if oil starts coming out. If you see oil coming out then your system either wasn't properly flushed or they used a degreaser but didn't fully flush it out or you still have oil leaking into coolant.
