Coolant Pressuring Up = No Leaks In Coolant System?

[ra8643]

Hello Everyone,

OK, so I have been trying to determine if my sludged oil may be coming from coolant leaking into the crankcase. I called my dealer and he said that Dexcool will not turn the oil gray - but sludge it up just like I was seeing.

 

Here is my question - I have opened the reservior several times hot since I changed the oil and added coolant. Each time it is pressured up. Does that mean that I don't have a leak in the coolant system (i.e. like a cracked castec head)?

 

Or does that not tell you anything?

 

Thanks,

Joseph

Doesn't tell you anything. I had a head gasket leak. Had coolant in oil and hot manifold gases pressurizing coolant system. Bad news either way. May not be your issue but something to consider.

Send a sample of the oil to Blackstone Labs and they can tell you what's going on with it.

Or, pull the valve covers and perform the visual inspection.
