Some kind of thick slimy brown sludge is getting into my coolant and building up very slowly in my overflow tank. With the radiator cap off you can see some of it floating around in the coolant. I noticed this a week ago and I drained it and flushed it with the prestone radiator flush. Now, a few days later it's coming back very slowly again. Is it oil? Or something else? 3 weeks ago I did a mini-me vtec head swap. My motor runs fine with no cels. The oil in the dipstick and under the oil cap both look very clean.
Rust. Need to do a professional flush and add a rust inhibitor when they fill it up again. Most anti-freezes have it in them already but it's around $3.50 for the powder stuff you just add to the fluid.
I had a mechanic do it for me, he is an ex-honda dealership mechanic. He better not have put it upside down. Yes both surfaces were cleaned before putting together the motor. He tightened the headbolts from the middle on to the outside then torqued them afterwards to somewhere around 50ft/lb
