I have a Venom Madix 110 ATV that is leaking oil at the junction of the cylinder and cylinder head. I assume that it is a leaking head gasket. Can I re-torque the bolts on the cylinder head to possibly stop the leak? I have attached photos of each side of the engine cylinder. There are four acorn nuts on top of the cylinder head and a hex bolt on the left side of the cylinder head. Which of these bolts or nuts should I tighten and to what torque?

Right Side. Oil leak is on black cylinder, just below exhaust pipe.

Left Side
