Can the PD camshaft seal be replaced using a conventional seal puller OR does the #1 bearing cap have to be removed as I have read some are doing? I inspected my cam last weekend, the cam was fine however I did not like what I saw with the tensioner so I am doing an early timing belt change to get it all while I am in there. I have removed the cam spocket and hub (have the correct tools). I did not see a need to pull the valve cover since I inspected the cam last weekend so I have not removed it at this point. If pulling bearing cap #1 is the recommended method, do the cap bolts have to be replaced. I have read where others say "torque them to 15 lbs and call it a day". On a Nissan I use to own, during timing belt changes I took 2 small finish nails and bent the tips 90 degrees, the nails pierced the seal and hooked in behind it and allowed me to use even force and pull the seal out. Not sure I want to do that with the BEW.
