I had a large and small torque wrench. Neither would fit in this spot. I picked up a harbor freight torque wrench and some metric crows feet to properly torque 2 cam cap bolts. After overtightening a bolt I realized the new torque wrench was garbage. I compared it to my trusty old torque wrench by tighting a bolt on my bike. When set at 20ft lbs the harborfreight was actually reaching 40ft lbs! I set the hf wrench to half the desired torque and retorqued the bolts.
