Hopefully a simple question.
Do I put the case sealant everywhere the two case halves meet or just on the outside perimeter?
Also, how close do I get to the bearings?
If it matters, it's a type4 1700.
Thanks. Todd. |

where else would u put it other than the perimeter? the sealant is to stop oil from getting out of the engine case...no reason to put it on the inner parts of the case halves that touch...just the perimeter

I don't know, you might not want the oil seeping from one are to another, I mean the metal partions are there for a reason. Does the metal w/o the sealant mate close enough for this purpose.
Maybe around the case through bolt holes might stop oil from seeping out.
Neither the Wilson book, or the Bug Me video really give much detail.
Do I need to worry about keeping the sealant off of the bearings? |

keeping sealant off of the bearings is extremely important...when i did mine, i followed around the perimeter of the case thinking about whether or not when the case halves touched if there was a place for oil to seap...the only places i can think where the case halves touch other than the edges are where the bearings are but there's no need to seal there as long as u have the o-rings around the main bearing studs...

If you think about it the sealant does have some thickness to it so a CAREFUL application at the main bearing webs will help stabalize everything

| I was taught to only use enough so you can still see a bit of the metal underneath. No gaps or clear spaces, but a nice even coating that doesn't "pool up". |

And with all the care in the world you still end up with bits of it showing up on the first 20 minute break in oil change.
At least I do.
What are you guys using for sealer these days?
What is that locktight product they have for sealing? 211 or something? Buddy of mine used it and said it worked great......

Sealant should not be applied to any of the main bearing saddle or cam saddle areas. This would affect your bearing crush, which may seem fine when you are assembling an engine at 70*, but could allow them to loosen and fret at high engine temperatures.
