Coolant in oil

Hello,

Usually when you have coolant that is mixing with your vehicle's oil it is going to be a blown head gasket that is allowing this. The other possibilities would be a cracked cylinder head or engine block, or a leak in the intake manifold gasket where and if your vehicle has a coolant crossover tube. This would allow coolant to leak into the intake manifold and enter the combustion chamber there and be forced down around the piston rings and into the oil sump that way. Here are a couple of links below explaining how to check for a blown head gasket below:

Hello again,

The only thing that I can think of would be a crack in your engine block below the piston travel that is allowing coolant to leak into the crankcase, but is low enough that you are not losing compression. The only way to check for this, unfortunately, is to disassemble your engine and do exploratory surgery on it. We can send you instructions on how to remove and disassemble your engine if you would like or we can send you instructions on how to do an engine swap if you would like. Please just let us know what you want to do and we can accommodate you.

Thanks,
