well i tested each cylinder, all over 150, averaged 165-180...not a blown head gasket, but when i took my in. manifold off, is there anyway i could have ran a coolant line into wrong place....no white smoke, good compression, no signs of coolant leak...should overflow hose be near the bottom, no moisture in oil....ne help would be awesome, coolant is magically dissapearing

 

A compression test is not an "end all" to check for a blown head gasket. It is a good indicator but not the final proof. That being said, if you have a high concentration of water to coolant, I have heard of it evaporating over time. How fast is it disappearing?

 

well every week i wash my car, check all fluids, so 5-7 days, its at max fill then between that time coolant is down at bottom of resi. could of i ran a wrong line off iacv or somewhere on the manifold where its blowin into cylinder, also i have fan wired to run on turn of key, so rad fan is always running also i ru 50/50 mix with a little extra water
