Its probably worth doing the crank pulley seal as well when your doing the timing belt as it's cheap and at 86k will probably start leaking at some point soon.....

Crank seal will only really leak if you put metal cam covers on
and it is a 'mare of a job to undo the crank pulley bolt and torque it up again afterwards.

You will need a 250 ft-lb torque wrench and some means of stopping the crank from turning. I don't know of anyone who has done it properly without having the engine out of the car (cue for posts about windy guns............)

Its not that hard, easy enough to do in the car once a basic tool has been made to hold the crank

?how does having steel cam covers affect crank seal?

Metal cam covers are used to replace the original plastic ones and stop the cam cover gaskets from leaking but because its normally the breathers that are blocked that causes the cam cover gaskets to blow in the first place, the pressure has to be released somewhere and its normally the crank seal that goes instead
