fixed rksport header leak

[derkyboy187]

I finally found a combnination that finally fixed my 3.8 rksport header leaks. I used OEM gaskets for the headers with locking bolts. Also for the header to Y-pipe connection I used copper gaskets. The part number for the copper gaskets is SCE4225 at summit. I hope this helps other people who have the same problem of the gaskets blowing out all the time.

i have pacesetter headers and do they come with the gaskets for the y-pipe? Or will those ones work that you have listed? Because i think im getting a leak from there and the bolts on flange keep coming loose.

didnt work tried the blue stuff

[derkyboy187]

yeah I've tried every gasket possible for the y-pipe and the only ones that worked were the copper ones from summit

Thanks man.. Just ordered some online like right after I saw this post.. Hopefully this works.. Thanks again..

[pdhockey31]

can't you also weld the y-pipe there instead of installing another gasket??

[derkyboy187]

no prob silverbird....that **** gets old. yes....but it would be a pain if you wanted to do work or if you needed to take them off

[1998silverbird]

Yeah welding the pipes would be a pain if you want to pull the motor.. Plus its ceramic coated and I think you have to grind that stuff off at the collector and weld the pipe on and then coat it again.. But yeah those gaskets are bad a$$.. Best flow yet on my headers.. No leaks at all.. Hopefully it will last.. This should be a sticky for all the Rksport header people..

[derkyboy187]

yes they work great...ive had them for awhile and they have been working great. The last resort would be using 2.5 inch V clamps if you didnt want to weld.

How did you guys use the SCE4225 collector gaskets from Summitracing.com with 2.25 in Diameter, dont we need 3" on the pacesetter y-pipe?

[BLLDOGG]

no, its only 3" at the cat connection

[99W68Firebird]

ah ok.. hey blldogg did ur EGR block off plate work? I just installed mine 2 days ago cuz i cant seem to get rid of my EGR leak for the life of me and now its makin like a whistling tick leak. I dunno what the hell is going on with that exhaust anymore.

do you all like your rksports? i know theyre a little bigger than the pacesetters so i was wanting rksports. especially if they were LTs.
pacesetters coming out with LTs for 2k2s?

[derkyboy187]

Well the Rksport headers are really nice if you can keep them from leaking. Just make sure you get those gaskets for the header/y pipe connection. I had a lot of problems with the gaskets from the header to the block. I used OEM gaskets plus locking bolts. I dont know if anyone else has tried that set up its the only on that worked for me. The rks are not LTs. Yeah I saw that post the other day....I hope its true.
