Hi to my Buick Brothers, hopefully someone can give some info on this problem. I have a 73 Buick Century Gran Sport (350) with a bad coolant leak. 6 months after the motor was rebuilt, i noticed white smoke coming from the hose that attaches to the air cleaner. I opened the oil cap and inside the valve cover was coolant milkshake. My friend is working on the car and he thinks its coming from the timing cover. I had a new one installed when the engine was rebuilt so is it a defective cover? I also checked the intake manifold and its not leaking from there. Is it somethin else? thanks.
Drain the oil and see if its all milkshake. You can get the cap to look that way from condensation. Check the actual oil. I would think intake gasket or upside down head gasket is the issue.
