Hello i have a 95 skylark 4 cylinder, i have what appears to be a coolant leak from the thermostat housing and i also have coolant mixing with my oil. Can the leak from the housing cause the coolant to mix with the oil? If not what else could be the issue? ---

Have your mechanic check for a breached head gasket. ---

- 1 for VDCdriver. It may not take long to do serious damage, so get it looked at soon. Yosemite ---

If this is the Quad OHC engine, the heads are bad about cracking. This was a very poor design by GM. I’m surprised that there is still one running around.
