hey scotty kevin from boston always with question my 98 volvo v70 non turbo the seal under the camshaft position sensor has a little leak what the best way to change that when you break that 10mm bolt im trying not to jump a tooth on the timing belt is it best to take the timing belt off what do you think

to get timing belt off, lock the cam, they make a special tool for that. or do like me, and invent you own tool using vice grips or other tools to lock em in place
