Hey guys. Just got finished swapping a crankshaft in a Kohler SV730-0011 and I'm trying to decide on what sealant to use. And also what is good to clean the mating surface that leaves no residue? I've heard carb cleaner does leave a residue but what about rubbing alchohol? The only sealants I have are permatex ultra grey and form a #2 non hardening. I've used the form a on valve covers and it done a heck of a job but I've never used the ultra grey. This engine did not have a gasket on it just sealant but I wanna make 100% sure it seals before I put it all back together and on the frame.

Either alcohol or Brake parts cleaner. Patience works best. I use Permatex Ultra black gasket maker. Good for 500° degrees. You ought to be good with Ultra Grey.
Another thing I do is get all the cover bolts snug, like with a nut driver, wait 24 hours and then torque to spec.

I use rubbing alcohol to clean the surfaces. The Right Stuff sealant sells their dealers come in an aerosol can with an applicator tip and sets up in like 1 minute. Whatever sealant you use just be sure to follow the directions to a T. So if it says to let it skim over or set for a specific period of time than do what ever it says to do.

And although you mention that you have used them before, less is better than more.
Every time I open an engine where sealant has been used the person thought they were caulking the deck boards on the Endeavour .

Lol yeah I've saw that before too. When I took this one apart, it had oozed a good 1/8 inside. Maybe I'll go with an 1/8 to 3/16 bead?

Oh by the way, what's the best method for pressing this new oil seal into the sump? I got the old one out.

I usually use a socket that is the outside diameter of the seal, and lightly tap it in until flush.

Thanks guys

I would never use this on an engine, you are asking for trouble. We are talking metal to metal sealant, not worried about UV or water resistant.
