Can exhaust manifold gaskets be reused???
 

Yes/No???

I have never reused one but you might be able to, depends on the condition of it when it comes off.

I agree, you MIGHT be able to, but my experience with gas engines says that you should replace them. I agree with what 06 said above, the condition would determine, but likely best to replace.

sure they can, but they might not seal, but anyway to save a $.

So everyone that installs a pyro replaces the gaskets????? I've read both ways...don't get me wrong, I always replaced the exhaust manifold gaskets in a gasser, but several threads indicated reusing them...just wasn't sure...

I'm not wanting to drill my manifold because I have a second one that's already drilled...keep mine for good.

And the set we got from DCX was $13/gasket...pretty pricey for 6 gaskets. Guess I'll need to call Cummins...

NO.....some of us install it after the turbo and always have, always will....


Yea, I know, let the flaming begin, its supposed to alter your reading by a few hundred degrees, but for the extra ease, and no filings or gaskets to worry about, I can do the math...:lol:

You can order the Isspro color coded guages for either pre or post turbo. It does the math for you. I just installed new manifold a few months back and I didn't pay as much for all the gasket's needed as your talkin just the exhaust ones. I got em thru Cummins but I don't remember a price on em. I know I got all the gaskets and new bolts for this project for under $60.

Pre and post turbo gauges???? What next???? Thanks Bubba, I honestly didnt know that!! I generally run the Attitude, so I have never had the gauges, but this is great info!!!

I reused mine

If installed post-turbo, what's a "safe" max EGT...keep in mind, the truck is more/less stock short being almost straight-piped and swiss-cheesed airbox...

I knew the made pre and post...even the Granatelli monitor I'm installing can read two pyro probes...but the threads I have read indicated they weren't nearly as accurate...

Cummins isn't much better. My price is still over $8 each. I get my sets for the shop from High Tech Turbo. Better price, plus it comes with new turbo bolts and a new turbo gasket.

Has anyone tried the High Tech exhaust gaskets?

For example FTE Diesel Multi Layer Steel (MLS) ?

I have always reused mine and have never had a problem just snug em down good and tight and maybe check them again after a heat cycle or 2.

I reused mine :w2:

And you shouldnt have to pull the manifold to drill and tap for a pyro. Just unbolt the turbo, stick something in there to block it, and use a magnet to get most of the shavings out.

I've had my manifold off several times and have reused all mine. Don't seem to have any problems.

ive reused mine on several occasions, no leaks yet

You don't even have to take the manifold or the turbo off to install a pyro. Just let the truck idle while you're drilling into the manifold and it should blow it out. Then just coat the tap in grease and the shavings will cling to it.

I dont have a fan shroud so I didnt want to risk that one lol

Ah, thats smart thinkin. :tu: One time I stuck my fingers in a fan on a small block chevy at 2,500 rpm. Luckily it was just some deep cuts

Man you did get lucky
