kate205gti 4 Posted February 16, 2006 Im about to swap my quaife lsd from my old 1.9 box into my new mi16 box - am i ok to use general purpose (outdoor) silicone sealant to seal the diff casing? cheers Share this post Link to post Share on other sites
Guest smokinslim Posted February 16, 2006 Probably, although instant gasket would be better. Doubt it would cost anymore than silicone either Share this post Link to post Share on other sites
Hilgie 16 2 Cars Posted February 16, 2006 Never use general purpose sealant as it lacks the additives to withstand oil and heat. Go to Halfords or any good motorfactors and buy instant gasket. Share this post Link to post Share on other sites
Sam 4 Posted February 16, 2006 RTV sealant is the best I've heard, you can get it from a motor factors. Halfords don't sell RTV. Share this post Link to post Share on other sites
kate205gti 4 Posted February 16, 2006 right ive got hermatite red instant gasket, universal blue allround gasket and all purpose silicon sealant - which one should i use on my diff casing? or should i find some rtv? and from where? i thought RTV was trade only? thanku Share this post Link to post Share on other sites
Miles 331 1 Cars Posted February 16, 2006 None of those, They will all leak. The only stuff to use is Wurth RTV (Trade only) or similiar, SO it might be worth poping into a local garage and asking them for a blob Share this post Link to post Share on other sites
Sam 4 Posted February 16, 2006 It is thats why you should go into a part factor to get it. Its the best stuff for it, or so I was advised by a few people. Share this post Link to post Share on other sites
ashley peddle 3 Posted February 16, 2006 couldnt get any so we used a pritt-stick instead... hopes it holds Share this post Link to post Share on other sites
Anthony 1,000 Posted February 17, 2006 Dave Baker's (Pumaracing) recommendation of using silicon sealant seems to have worked wonders on my sump - if it works on a sump, then I see no reason it won't work on a gearbox casing just fine.... Share this post Link to post Share on other sites
kate205gti 4 Posted February 17, 2006 None of those, They will all leak.The only stuff to use is Wurth RTV (Trade only) or similiar, SO it might be worth poping into a local garage and asking them for a blob could u squeeze some out into an envelope and stick it in the post? hehe! okies will go find a garage who actually puts gearboxes together - otherwise what motor factors? GSF and bennetts didnt have any (GSF recommended the blue stuff and bennetts didnt have a clue) will use rtv AND silicone sealant just to be on the safe side cheers Share this post Link to post Share on other sites
ashley peddle 3 Posted February 17, 2006 i have a decent place near my work called brown brothers kate - want me to go lookie for some RTV tomorrow? Share this post Link to post Share on other sites
Anthony 1,000 Posted February 17, 2006 okies will go find a garage who actually puts gearboxes together It's not a gearbox specific sealant so it doesn't have to be a gearbox specialist. Share this post Link to post Share on other sites
petert 554 Posted February 17, 2006 (edited) I use ThreeBond 1211. It's made especially for high viabration metal-metal seals eg motorcycle gearboxes. It's the best! Edited February 17, 2006 by petert Share this post Link to post Share on other sites
ashlee205gti 1 Posted February 17, 2006 I use silicon sealant for a number of things. It also help when it comes to removing parts aswell. Share this post Link to post Share on other sites
kate205gti 4 Posted February 17, 2006 noone stocks Wurth RTV have tried bennetts, webbs, GSF and local auto factors so far any ideas?? thankyoo Share this post Link to post Share on other sites
Miles 331 1 Cars Posted February 17, 2006 No will stock the Wurth RTV to sell bar Wurth UK and that you need a trade account to buy some, A local garage should keep something or something similar Share this post Link to post Share on other sites
ashley peddle 3 Posted February 17, 2006 No will stock the Wurth RTV to sell bar Wurth UK and that you need a trade account to buy some, A local garage should keep something or something similar naa you dont - can buy it mail order over the phone but their customer servie is worse than crap (esp. considering their prices!)

pug_ham 242 3 Cars Posted February 18, 2006 I don't think I used any when I fitted my diff & I have no leaks. Graham. Share this post Link to post Share on other sites
James_R 3 Posted February 18, 2006 I use marine grade RTV, has a wide enough temp range and is meant ot survide salt water and diesel. Been using it for ages now and seems to work a treat on everything I've tried, inlet manifold to heads, gearbox casings, etc... http://www.decoratingdirect.co.uk/viewprod/b/BITHA6/ opps forgot to add here's the link to it, I use black, but guess you could use white or clear if you wanted ot be a wierdo.
