Loctite 574
Very expensive, but works great. |

The best sealant I have found for the TIV case is Curil K 2- I carry it at my store as it is a German sealant that is hard to get.
Huge misconception! Thinking that way is similar to the "Bigger is better" way of thought and it's just not true... When I have used 574 engines would begin to leak after 6-8 months of service. I have used literally hundreds of sealants on TIV engines to create the absolutely no leak reputation we have gained, Curil K 2 is the best case sealant I have ever seen, and its not messy to use or to clean up! My sealants handbook is at the publisher now, 45 pages dedicated to the proper sealing of the TIV engine ONLY! |

Its a dark yellow/brown color. Not as dark as 3H... tough to describe, but its not green. |

Then is it the stuff that actually gets hard? That comes in a bottle with a brush attached to the lid? |

The green stuff is Curil-T, same brand, different product. (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)

It never dries and is a very pasty substance with a lot of wax content. The wax repels the oil, so this sealant is considered an "Oil barrier"..
It REALLY works. I just used it to seal up the case halves of a 40,000 buck TIV engine that I have been working on for almost 1.5 year! |

I used Dow Corning product (gotta look for the exact name) that does similar things...never dries.

The Dow-Corning product is #730
It works very well for sealing case halves, etc. However at $70/tube its a silly product for a guy who builds an engine every few years.. That Curil is the schiznitz also... or Yamabond fyi: 730 Solvent Resistant— Contains fluorosilicone rubber, which resists swelling when exposed to fuel, oil, and most solvents. Nonrunning paste for repairing fuel lines and tanks, bonding components exposed to solvents, and making formed-in-place gaskets. May corrode certain metals (including copper, brass, zinc, and carbon steel). |

Try Yamabond#4. Its sole purpose is that of a case sealer. Comes in a tube for about 7 bucks. I have used it for years on motorcycle race engines. Good stuff.

What's in the yamabond.
We always use the loctite, for fours and sixes. But I think I might try some of the other stuff out there. |

You don't want to know... really..... Group: Members Posts: 2,514 Joined: 12-September 04 From: Newport Beach, California Member No.: 2,743 |
Whatever it's worth.
I used Yamabond ONCE once on a type4 .. Never again.. It hardened after about six months and leaked in three differant places. WHAT A PAIN.... I assume that the case temps are differant than bike engines. (truth is I don't know) When I took the case apart. The Yamabond had lightly carboned up and wasn't pliable any more... And I don't believe that engine was EVER overheated. (don't know for sure) This is just my experience. That don't mean it doesn't work.. Just not every time... Now let's talk about the dental floss trick.. Jake you listening????? Never again.... Curil rules. Twystd1 |
