BirdMobile Posted July 31, 2014 Share Posted July 31, 2014 (edited) Quick question - how resistant to gasoline is anaerobic flange sealant? Thinking of using it on a carburator adapter plate for intake manifold. Bad idea? Edited July 31, 2014 by BirdMobile Quote Link to comment Share on other sites More sharing options...
Adam N.D.J. Posted August 1, 2014 Share Posted August 1, 2014 My favorite sealant. You have actually make a Subaru engine not leak with the stuff. That said, yes it is resistant to fuel, but only when fully cured. Also you need to remember that it fully cures in the absence of oxygen. So for small stuff like that I will apply a very thin coat, bolt it together, then take some clean motor oil and apply it with a small brush around the seam. Then I just let it sit over night, clean off the oil and should be good to go. Quote Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted August 1, 2014 Share Posted August 1, 2014 I have used Shellac several times, including on my Weber install, always with Great Results. ~► http://shop.advanceautoparts.com/p/permatex-indian-head-gasket-shellac-compound-2-oz-20539/7160106-P Kind Regards.

Loyale 2.7 Turbo Posted August 2, 2014 Share Posted August 2, 2014 So, no gasket there, only sealant? Quote Link to comment Share on other sites More sharing options...
ferox Posted August 2, 2014 Share Posted August 2, 2014 Gasgacinch is the best sealant for carb gaskets. http://www.autozone.com/autozone/accessories/Edelbrock-4-oz-gasgacinch-gasket-sealer/_/N-25c6?itemIdentifier=214303_0_0_ http://www.gasgacinch.com/gasgacinch_002.htm Quote Link to comment Share on other sites More sharing options...
BirdMobile Posted August 2, 2014 Author Share Posted August 2, 2014 So, no gasket there, only sealant? Yep. Perfectly flat surfaces... ideal for Anaerobic sealant. If it doesn't work right for whatever reason, I can always tear it down again and use traditional gaskets. I see this as an experiment of sorts... I'll keep you updated on the results. 1 Quote Link to comment Share on other sites More sharing options...

BirdMobile Posted August 2, 2014 Author Share Posted August 2, 2014 Photo of the final Weber carburator assembly, with new adapter plate and Anaerobic sealant. I used stainless bolts and lock washers throughout. If the sealant lasts, the whole setup should last to eternity! Quote Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted August 2, 2014 Share Posted August 2, 2014 Well, in my Case, I used the Traditional thick paper gasket, previously smeared in Shellac, which is Gasoline Resistant, on both sides, and that thing works awesomely Perfect, plus is fast and easy to do, also it doesn't need any time to cure, just smear, put and go... I've used gasketless seals on transmission's oil pans, smearing Mega Grey or Ultra Grey Silicones with great results; but the kind of gasketless sealing you're doing on the Carb, is something new for me. I hope it will work fine for you, and that it will last many time... Kind Regards. Quote Link to comment Share on other sites More sharing options...
