this is a datsun 1200 with a ca 18 motor intstalled...
oil leaks down the back of the block that run down the gearbox, smells like burning oil and smoke out the exhaust when given on throttle??
compression is good across all four cylinders!
however the oil's only coming from cylinder 4...
i assume either worn valve steam seals or a blown head gasket??
can u help??
