is my head gasket blown?

jlE90 · 03-03-2011, 01:08 AM

i have small white looking gunk in my expansion tank and slightly low on coolant. my oil cap is clean and car is not acting up, is it something i should be seriously worried about?
my car has 62k miles

Have you ever used tap water? Tap water will form white deposits in your cooling system. Also, have you ever changed the coolant? If not, then now is the time.

this is the second time im checking the coolant on this car. i only put 4000 miles on it since i got it. i dont have warranty. is coolant change hard? can i do it at my house?

also if i previously have a leaking oil filter housing gasket and got it repair, would a little oil end up in the expansion tank?

Here is the DIY, you may want a mechanic that works on BMWs do it if you are not mechanically inclined.

How many miles are on the car. The number of miles you put on it since you got is immaterial.

What color is the coolant?

i have around 62k miles. coolant was orange in color. i've just notice the white gunk last night when i took off the cap for the expansion tank.

yes...some can as coolant flows through there and when you remove it there is residual oil which will run into the coolant ports...but it should be a very small amount and should have been properly cleaned up during and after the repairs..
