My cheapo fel -pro exhaust manifold gaskets finally burnt through (lasted about 4 years) so ive ordered the remflex gaskets ive heard good things about .Ive read there is no need for gasket sealer on these? i will take out the old gaskets and give things a good cleaning before installing the new ones.Any additional advice is always appreciated

 

I was looking into these gaskets as well. The website quotes this:

INSTALLATION TIPS: We want you to get the most from your new Remflex exhaust gaskets. To assure your complete satisfaction, please follow these basic installation guidelines:

1.) DO NOT BEND! Remflex gaskets are designed to withstand clamping force and incredible heat, but not bending.
If you bend them, they will break!

2.) Do not over tighten. When properly installed the flange should be tightened evenly - See the suggested torque range.

3.) Longer bolts aren't necessary. Though Remflex are thicker than other gaskets, standard length bolts will work fine.

4.) Do not use sealers. Silicone and other sealers cannot withstand the same temperature as Remflex gaskets, and can actually cause leaks.

 

I've always had good luck with the FelPro gaskets. Regardless of the exhaust manifold gasket used, you shouldn't need any sealing compound.

 

You are not really supposed to need any gaskets at all.

 

My W had leaky exhaust manifolds when I got it. I had several manifolds, used the best ones and used remflex. No leaks and sounds great.

 

I use Percy's/Patriot Seal-4-Good multi layer aluminum.

 

Remflex gaskets do NOT require any coatings or sealers. The people who designed and manufacture these gaskets know best how to use them. As noted, pay attention to torque specs. If you overtorque and crush them it destroys them. READ the instructions.

 

have had good luck with remflex long term.. ++15 years with stock stuff..

Make sure head and exhaust manifolds are clean and straight as can be

I get a large flat file to get a feel how warped the head exhaust and exhaust manifolds are. if really bad one might have to resuraface them.

Then I wrap 220 grit sandpaper around the flat file to final clean with surfaces.

Remflex can make up a fair amount of warpage.

Do not over torque follow instructions on package.

I finally got around to changing out the exhaust manifold gaskets ,it went easy enough,i think i spent more time reinstalling the alternator bracket. Definately stop my ticking at start up . as far as torquing to spec i can't see how anyone could get a torque wrench in some of those spots with the thorton shorties! Maybe from underneath if i had a lift . Of course it would be easy if the engine was out. im going to look at some torquing options before i just call it good by hand torquing

 

Can you get to those hard-to-reach bolts with wobbles & extensions? That would be better than gut und tight.

 

not from up top I’m going to try from under the car ( of course that means getting this worn out old body under there &#128563

 

Sometimes you need a torque wrench dogbone extender. Obviously be sure you compensate for the extra length when setting the torque.
