I've been breaking in my rebuilt 350 that sat since Dec 06'
. but a few concerns have come up. Probably nothing major...
Oil pressure is fine, but after driving it around my neighborhood, I see very small amounts of oil sweating from the cylinder heads. You almost cant tell unless you really look for them. However on the back side of motor where the casting numbers are, you can see a little more.
Could the cylinder heads loosened for sitting so long?
Could the head gasket be the culprit?
Another thing I must add, is that I'm running full synthetic oil....
Should I take the valve covers off and torque the heads down?
