Well mine were leaking, Seals and Gaskets are common leak points,

From what I understand, the Crank seal plate is to prevent the belts from getting chewed up, it won't prevent leaks.

Gaskets and Seals will inevitably have to be replaced.

You missed the point. There is no "procedure" to follow for this, and there is no actual data that adding a sealant actually helps. If anything, it opens you up to further possible complications...
Too much sealant = gasket doesn't fit into the groove right.
Not enough sealant = what's the point?
Too much time from when sealant is applied and it starts to set up = gasket again doesn't sit in the groove right.
Not enough time for sealant to set up at all = gasket more likely to fall out during install...

Also, for all intents and purposes, the OP is "Joe bloggs down the road who wants to have a go at diy, lol."

There's no need to complicate this repair anymore than it is, which it really isn't.
Buy OEM parts from FCP.
Replace both the cover, gasket and bolts.
Clean the head mating surfaces really well.
Make sure the new gasket is seated properly in the new cover.
Carefully slide the cover into place, making sure the gasket doesn't get caught on anything.
Before threading in bolts, go around with a mirror and make sure the gasket is still seated properly.
Screw in bolts to finger tight.
Torque to proper value in proper sequence.
If it leaks again at some point, use FCP warranty to replace parts and repair again. It'll take you half the time the 2nd time around, if you still own the car at that point.

Correct. I'm saying that I would not replace a good crank seal. Typically speaking, this seal is good for a long time compared to the rear or when comparing it to the VC for example.

Yes true VCG and OFHG leak more often, but It's a good idea to get the seals checked over. Don't want any nasty surprises.

Replacing Crank Seals might be a dead easy job for you, but not for someone like me,

I had both front and rear crank seals replaced at a garage because mine were leaking. Haven't had an issue since.

There's also a very specific procedure for replacing the front, and I wouldn't recommend touching it unless it's actually leaking.
Lol don't worry I'm not doing any of this myself I just have to buy the parts for my mechanic.with my luck the engine would fall out and crush me.

Yeah thats a good point i won't use it I just added it because I need it to do my valve cover gasket on my focus thought you might have to do it on all cars but seems unnecessary. Thanks for the info and sharing your experience i appreciate it.
