Should I replace the front crank seal?

[Wagon_Wheel]

Hey dudes,
Got my harmonic balancer off my 5ltr at the moment, and was thinking about replacing the front crank seal as its right there?
Should i do it or just leave it until it starts leaking?
Any tips as to getting it out or putting the new one back in, never done one before and i dont want it to leak if i do decide to do it.
Any help is much appreciated.
Cheers
Geoff

is it hard to do this? ive got a bit of an oil leak around this part of the engine, and this could be it

... getting the harmonic balancer off is easy, and the seal is right there, dont need to take anything else off.
Just dont wanna pull the seal out and put a new one in and not do it right.
Do you just knock the new seal in? Do you need a special tool for it?

at work we press them in but i suppose you can knock them in just make sure they sit square. I dont know how well youll go removing the old one on the but good luck

if its leaking oil stocky 90% of the time its the rubber seal on the bottom of timing cover

Hmmm... might just leave leave it then, i dont think its leaking. Well very minimal if it is.
Dont wanna put a new one in, and find out its not in properly after hours of putting everything back together again

its not hard to do itll basically sit flush all the way around might be hard to tap it in with the snout sticking out waaay easier with timing cover off
