at a loss of what to do, blew passanger header gasket 4 times!

1995 Mustang 5.0
62-1 turbo B&G kit hotside
Turbo on the pasanger side ( the side that keeps blowing)
Headers resurfaced

turbo owners only reply with turbos on the passanger side

I continue to blow header gasket (passanger side only, the side the turbo hangs on). I swapped to another turbo hotside think the other was just junk now using a B& G hotside

resurfaced Header flange
Using the good Remflex gasket
AND
Stage 8 locking bolts

Although, I did notice this time the side that Blew the Locking clip fell off and the bolt was loose......


This time I was thinking of doing the Percy's Locking bolts, percy's gasket, copper RTV on the threads
and bracing the header somehow I dont know...

I got tired of blowing header gaskets on my turbo car and ordered a set of ARP header studs. Get the upgraded 12pt nuts and you can tighten the #### out of them without worrying about stripping the threads. I am no longer using a header gasket, only copper rtv.

I used this same combo on my personal turbo stang for years, with no problems if any of the header bolt's back out you will loose the gasket.

ARP sells 2 different head stud kits. 1 comes with standard nuts, the more expensive comes with 12pt nuts. The standard nuts would not fit. I had to end up buying the 12pt nuts.

damn wish they only sold 8! so, did you use locking washers behind these? Did they back out give me details...

Im super sketchy at this point, blowing gasket 3 times, ( may have been a warped surface) now got a whole new b&G kit I spent money to have it resurfaced, spent money on the remflex gaskets AND Stage 8 bolts wich obiously the clip fell out.

I run the ARP header bolts with Copper RTV with no problems. As stated above if the bolt backs out you will lose the gasket everytime.

I have remflex gaskets now and have had zero issues.

RTV had worked for me also, but the remflex are close to bullet proof.

The outside surface of the head could be warped. It happened when I had an strim and then when I had a 70mm on my 93 gt.

I love the header studs with the turbo kit. It makes installing the passenger side header with the turbo attached a 1 man operation. I apply the rtv then put the header on the header bolts and push it towards the head until the studs are just beginning to protrude through the flange. Then start each header stud nut before pushing the header all the way up against the head. Tighten the nuts just until the rtv starts to squish out and then wait an hour. After an hour tighten them the rest of the way. I bought a stubby 1/2 craftsman wrench to make the job easier. Then re tighten the headers after running it for the first time. I also check them every time I have the down pipe off.

I ran the gaskets that came with the on3 kit, the bolts also. I didn't use rtv at all and i still haven't had any problems. Sorry to hear about your frustration. Although I will say i have had a bitch of a time getting the crossover to stay sealed up. Six of one ya know.

I'm not a magazine racer, my car is actually fast.
I also have a Honda civic but, mine has a bigger, uglier driver.

I ran copper rtv and bolts for years held just fine. I also braced my turbo to help with the weight after I did my T6 upgrade. This year I'm trying STOCK gaskets with rtv on them.

arp studs and rtv is what im aiming towards. I have a 62-1 turbo but maybe I need to brace it.....

I also noticed There is oil leaking from the valve cover, coul be the reason why # 4 cyl gasket blew. I know #1 was due to bolt backing out.....

arp studs in the head moly lube on the top head bolts and thread sealer on the bottom head bolts if everything is properly torqued and cleaned then it should outlast the block. and copper rtv on the exhaust will fix it for good. i suspect if you let kurgen or someone very good at tunning it you will be much happier with it and in the long run it will be much more worth it to have a car that doesnt break down all of the time

I'm running ARP header bolts with 5/16" 12-pt heads (I had some clearance issues) and these gaskets.

I was having problems with header leaks, even after resurfacing the headers. These gaskets solved the problem.

I have eBay headers and the placement of some of the primaries didn't leave much room for the bolts or at least not enough to get a wrench on them. I used a torch and a hammer to make some clearance, and then got the 5/16" head bolts so I could have enough room for a wrench.

If you have completely flat surfaces on the headers and heads, the copper rtv should work. If you have any gaps, the rtv will dry up and blow out after a few heat cycles.

Not a Turbo, but in the same boat. I have one head that just wont seal. Gt40p heads and mac p headers. Looks like just not enough material around the port on the head. Rtv, gaskets, rtv and gaskets. Nothing lasts more than a few days. Might want to check that also.

Sent using nothing

Got my ARP 12 point exhaust studs today...

so I was thinking, I DONT want these fluckers to back out! Should I install lock washers as well? Or maybe ill put copper RTV on the nut threads too.

and with just RTV as the gaskets, I was thinking of putting a nice amount on the flange, letting it sit for 30 min to let it skin over, then install it, sound good?

welp, header is instaled and rtv is curing... I had to clearance a few primaries to make room for the nuts and washers, I also had to drill out a few holes bigger so the header would slide on the studs. But its on now. I applied the Copper RTV, tightened the nuts just enough were the rtv squeezed out, waited an hour or so, then tightened them all the way, then torqued them. Now I guess I need to let it sit for a whole day before running the car?

Man I hope this is the fix! After I run the car, Ill retighten the bolts again ( it sucks because in order to tighten the bolts I have to take off upper change pipe and both down pipe sections .

I had the same problem..... Boostbrothers kit turbo on passenger side. My dumbass first put the gaskets that came with the turbo kit in (terrible decision). Then after that I went to oreilys and got their oem gaskets... Problem is they gave me wrong shape of gasket (square instead of oval). So those blew out within a few heat cycles. I finally did some research on a good brand of gasket and heard good reviews on the percy tri-layer aluminums and they work damn good. Didn't have to use any rtv silicone so there wasnt a mess. I also got some new bolts, and tried out the medelin or whatever that brand is called. Seems to be holding up fine. As soon as I get my car back from the tuners I'm gonna re-tighten the bolts. Also how are guys bracing their turbos? I would love to see some pics. My passenger header seems to be holding alot of weight, beings its carrying my turbo, some of my crossover as well as my downpipe. I dont wanna risk cracking my header.
