Replacing front crank seal

NWHybrid · 01-23-2004, 08:13 PM

I'm rebuilding a B18 for my civic and want to replace the front crank seal behind the crank timing pulley... what's the best way to get this out? the round seal.. do I need to remove the oil pump to do this correctly?

I believe you can get it out without taking that plate out. just be careful not to knick anything. if there is anything scratched/knicked, it will leak. I would just take that whole plate off, it'll be easier. Also, don't forget the new sealant. Good luck

If the oil pump is old or has a lot of miles on it, then just replace the oil pump.

no the crank is clean...
I've done small blocs before but never a 1.8

Sealant? You mean like rtv onhte outer edge tha touches the metal?

The oil pump has 65,000 on it.. stock LS block

yeah, you'll see where the old rtv sealant was. just scrape it off and redo it.

Personally, I'd just replace the oil pump. It already has a seal in it.

The oil pump has 65K, it's still breaking in!

The seal is real easy to replace if you've already got all the stuff in front of it off. The best (and quickest) technique i've found is to get a self tapping sheetmetal screw, screw it into the middle of the seal just enough to where it will not pull out when you pull on it, You can put the screw in anywhere around the seal just make sure you get it in the middle of the seal so you don't damage the pump of the crankshaft. You should then be able to work the seal out pretty easily. Put a thin layer of rtv around the new seal and some grease on the part of the seal that contacts the crank and work it in by hand. It shouldn't take more than 10 minutes tops. For all the haters, this does work, i've done it more than once, no metal shavings will get anywhere they're not supposed to, they should stay in the old seal if you are careful.

just wanted to add, this goes for just about any application, if you are going to use some kind of "sealant" or silicone type gasket maker...go to your local honda garage and get some honda bond! It's the best thing man could have! lol
