Manifold to adaptor Problems
My exhaust keeps blowing out between the mani and my adaptor, this is due to my poor first time fab skills. So until I can make a new adaptor or order a BMC I need to find a way to stop it. Is there any good gasket material to use OR wil JB Weld hold the heat.
I was hoping to JB weld (use JB weld as a sealant , not as strength support because it hardens better than RTV Exhaust Sealant) it for the time being. |
Re:Manifold to adaptor Problems
haha jb weld on your exhuast. let me know how it goes

Re:Manifold to adaptor Problems
lol jb weld it!!!
what isn't jb welded rated to 500 F? |
Re:Manifold to adaptor Problems
use an old liscence plate as your gasket, cut it all good and bolt it up. it seriously works.

Re:Manifold to adaptor Problems
I use a peice of sheet metal and so gasket sealer. Works fine for now. Still want a new adaptor but in time!

Re:Manifold to adaptor Problems
Do not use sheet metal, it will not withstand the heat. I went through the same problem and the sheet metal brokedown and went into the turbo. Chipped some of the fins. I ended up using the stock maifold to turbo housing gasket on dsm's. I just doubled up the gaskets and have had no leaks. The sheet metal lasted for a couple of weeks.

I need a bmc one...but I never see him on anymore...could someone get ahold of him for me?

fyi i picked up the dsm gasket as well. its like a .5mm ceramic layer sandwiched between two thin sheet metal layers. |

Ya, I'm going to honda and getting a oem copper gaket tonight. I plan on removing the sheet metal this weekend

Re:Manifold to adaptor Problems
i just used some RTV. i think it leaks

Re:Manifold to adaptor Problems
So I can use my stock copper gasket on my HF manifold when I do the turbo? This would just be another thing I don't have to worry about anymore ... also am I going to need to gasket my manifold to adaptor and adaptor to exaust housing?

Re:Manifold to adaptor Problems
you can email the bmc guy at sgoertz@sbcglobal.net his name is sam

Re:Manifold to adaptor Problems
I would suggest not using copper manifold gakets. It is a heat conductor which will tend to conduct the heat from your manifold to your head (engine head). Naturally the coolant will soak up the heat, but it also cools the manifold, which will cool the exhaust which then makes your turbo less efficient and increases turbo lag. Heat is normally the enemy, but you need as much heat as the rest of the engine will take to go through the compressor. Use the layered stainless OEM Honda gaskets (crimped around the ports) if possible. Stainless does not conduct heat as well. You should use gaskets for all connections if available. Some builders use the hi temp copper spray on gasket sealer (rated for about 500 deg f made by permatex) for thier gaskets and/or gasketless conections. I know that most turbo applications will see in excess of 1200 deg, but the engine builders still use this sealer. I know Mopar does not use gaskets at the turbo.
