| Post subject: | remflex reuse |
When I put the intake and exhaust manifolds back on my 62 225 last winter I used Remflex gaskets. I'm now taking the intake off to replace with a super six. The gasket sandwiched between the intake and exhaust came off in pieces. For some reason I was under the impression they were reusable. Now I'm wondering if I should pull the exhaust off and replace the big gasket there as well. Ideas??? Thanks. Joe |

Attempt to re-use the manifolds-to-head gasket only if you want to do the whole job over again. This junction needs a new gasket each and every time. |

Thanks Dan, that's what I was afraid of. Tomorrow I'll take the whole thing apart and start over. Joe |

I have reused the Remflex 2.25" donut exhaust gasket many times. If the surfaces are real clean it won't stick. On the intake if you have any paint on the head it will stick, so sand or scrape it off. If your racing and do manifold swaps spray some cooking oil like (PAM) on the gasket and it will come off just fine with out sticking. The main thing is to not over torque and let the manifolds move around (expand and contract). I use brass Dorman nuts, silver "Never Seize" and torque to 5 pounds. I use the two castle nuts and big brass spacers per the book on the front and rear. I have had excellent results with no leaks! I worked with the company to develop this process. |

Great...groovy...grand......but that's not the gasket he asked about. |

The one Remflex gasket I have even encountered was a manifold to head gasket on one of EricW's motor. It shredded when I pulled the manifolds off the head. It took me about ten minutes of scraping to remove all the leftovers from the head and intakes. I wasn't impessed. I have actually had good luck reusing the normal Felpro manifold gaskets several times. Not the exhaust doughnut, but the head to manifold gasket. I have even had good luck reusing Felpro head gaskets. I know I am a real cheapskate, but if your mating surfaces aren't warped then you should be able to reuse the Felpro gaskets (unless they stick and tear). |

I've seen cheapskates and I've seen cheapskates, but really, let's be serious. If you don't have the money for a new manifold-to-head gasket, you don't have the money for gasoline to drive the car with. |

 Heh. This was back when my family lived off of student financial aid. Everyone was going to college and working whatever part-time job they could get. We were lucky to have $500 in the bank for the month to feed an house our family of five. We almost didn't have the money to drive a gasoline powered car, but you do what you gotta do. I did a lot of cheap things to get by that I wouldn't do again, unless I really had to.

Reed, I remember those days!! Living pay check to pay check and never getting ahead. I couldn't afford gas (and it was at $.26 a gallon) and had to walk to town, it was up hill both ways. The good old days!!! Anyway, I was disappointed in Remflex. I had used a torque wrench and it was together for less than a year. A learning curve there. Back to Felpro. Thanks. Joe |

Since the exhaust is coming off would it do me any good to grind out some of the exhaust outlet to make it closer to 2 1/4" or am I better off leaving it alone?? Thanks. Joe |

I spent some time on mine and opened it to 2.250". At low velocity it helps a little on initial torque below 2000 rpm not having the lip and turbulence. It flows and breathes a little easier. |

I personaly would go with a known 100% sure, seals it up gasket everytime ie Remflex.I'm sure many folks have great luck with Felpro and the likes but the Aussie and Remflex gaskets were developed to make sure of a 'one time and you're done'gasket install.I don't believe Remflex ever said they were reusable nor do I think Felpro markets their gasket as reusable? I have Clifford intake an headers on my slant and used the Remflex,had to loosen everything up and reposition after install and startup,resealed just fine and that was 10thou miles ago. |

Ted, thanks, that's the way I was leaning. It's off, I've got a die grinder and carbide burrs so why not. I found an exhaust gasket that has the 2 1/4" hole in it so I've got a good template. 6shotvanner I've got to say my experience with Remflex was less than perfect. For the money I spent on Remflex I could have gotten a whole bunch of Felpro gaskets. One summer and mine came off in pieces. I'm glad you've had good luck with yours. Joe |

Joe,I guess it boils down to expectations  I worked in a pulp mill for 25yrs and as a pipefitter used a lot of graphite gaskets over the years.Having seen first hand what they can accomplish it was a 'no brainer' for me when I heard about Remflex gaskets(on this forum from Ted)and haven't looked back so to speak.I know that they will flake apart when removed even after a short time but graphite will 'absorb' bits and pieces of itself when tightened down so they don't require a spotless cleaning of old gasket.If I was to remove a Felpro gasket(or any brand of gasket)I know I'll be cleaning the mating surfuses and I also would not expect to reuse the old gasket.I more than likely luck out when I shifted mine after 20mins of run time but hey it worked.I'm just having a hard time understanding why you're upset that it fell apart after a few months,would you really consider reusing a Felpro after that same amount of time? Not a flame,just thinking outloud

My point of view is I wouldn't reuse Felpro. They're inexpensive enough so it would have been easier for me to buy a half a dozen of them. I don't mind cleaning up a mating surface before putting a new gasket on. Then I know it's clean. I'm really kind of sorry I brought it all up. Joe |
