Header Gasket
 

So many have said that the oem header gaskets will fail on an aftermarket catless header. I was going to get the grim speed headers and call it good. Then while looking at the JDL auto headers I am going to order i see they offer this sweet kit with the gaskets and locking nuts so I don't have to go back a re torque the header nuts! The only problem is that it says it come with "Pair of OEM header gaskets" lol. I would link their site but I dont think i can. Any opinions on whether I should stick with the Grimspeed or will the ones JDL auto offer work just as good? @ATL BRZ wana chime in??

The picture is the JDL gaskets that says theyre OEM. dont look oem to me

I bough the uel header with the promo of 86 fest. Came with oem gaskets and their locknut package. Basically that offer is plug and play, came with the hardware you need to install it. You cant go wrong with jdl header, and their warranty is hard to beat. After a heat cycle i re-torqued for peace mind but is not needed.

Sorry, I don't understand the question ......:bonk:

Are you asking which header to buy or which header gaskets to use ..... ??

Old OEM EJ dual port gasket
Same part number from late 1990s to now

New style is Stainless steel embossed gasket

Grimmspeed gaskets FTW

I'm running the JDL gaskets with a Nameless header, which is notoriously tricky to keep from leaking I guess... I did have a leak, but not from these gaskets - it was at the header>overpipe where the bolts I have were really tricky to use. YMMV.

Lol gasket. Trying to see if the jdl gasket performs as well as the grimmspeed

Well, OK.

I don't think it would make any difference. It's not so much the gasket (as long as it fits) as how the header is tighten up against the head.

I'd make sure the header fits snug (when it is relaxed) put the gasket in place, then tighten the nuts, moving from one to the other, a little at a time, until they are "manifold nuts tight" ...... or your favorite torque specification.

Heck, back in the day, we used to "make" (cut our own) manifold gaskets out of a sheet of asbestos. Be damned the dust ...... we were bullet proof .... actually we didn't know ..... :cry:

Why do the stock gaskets fail on the aftermarket headers??

One day Ima buy u a beer old man

Well, I would guess that the OEM gasket was being re-used was compromised when the old header was taken off .......

OR

the OEM gaskets can be thinner because the OEM header fits better......

OR

the robot that tightened down the OEM header did a better job


:iono:

Hey, I'll take you up on an iced tea ....... I had to quit drinking 20 some years ago ....... the whisky was getting too strong ....... :bonk:

I used new OEM gaskets when installing a Revworks catless UEL header. Works like a charm after 2 years. Perhaps if you have issues with an aftermarket header where the end plate (or whatever you call it) isn't completely flat where it meets the exhaust port.
