But if u make one, make a legit one. Using proper tools to take off the crank, not just banging it out

[pancakes562]

do it man! that problem comes up a lot and shops charge an arm and a leg to get it replaced! a write up would save us silvia members money (:

bang out the crank? proper tools?

If this is for a sr20 you simply take the front cover off of the engine and pull the old main seal out, push the new main seal in. (Literally just using your fingers) Use a dab of silicone rtv around the perimeter of the seal. Reinstall front cover.

Maybe a KA is harder. But, the sr20 is literally so easy there would be nothing to write about.

Why go though all that effort of pulling the front cover? Pull the crank pulley off, thread two small wood screws into the front main seal by hand and wiggle it out and replace it with the new one. Just make sure not to nick the sealing surfaces.

Or you can pull the front cover along with draining the oil, pulling the lower pan, oil pickup and baffles and never having the top of the cover seal right again once you put it on.

Even better man. I installed a ve oil pump when I did it so I didnt even think about that.

It's really just that simple? That's for the KA right? I haven't seen anyone specify yet..everyone is saying that the SR is easy and the KA isn't?

[ray666]

did mine a year ago. it took me less than 30 mins to do.A write up for an sr is not necessary.

[dreaMervaj]

I replaced the main seal in my first KA motor (7 years ago) and it was a PITA. Wish there was a how-to back then.

Proper tool to remove the crank pully

That would be two pry bars and a careful hand!

OP: Honestly I wouldn't bother making a write-up on something so easy.

If you're changing your crank seal I would HIGHLY reccoment that you change your PCV valve as well. They are hardly ever changed because they're such a PITA. A lot of times a clogged PCV is the primary cause of your crank seal leak as well. You've gotta remove your alternator and lower alternator bracket to get to it. It's screwed into the backside of the timing cover under the intake mani. Just be aware that you're probably going to break the PCV hose taking it off since it's so hard from age/heat. You can use bulk hose to replace it with, but obviously the OE hose would be better. Just make sure that whatever hose you use is good for oil, NO COOLANT HOSE. Now THAT is a job worthy of a write-up!
