I am ------- fedup, tried to tune my car and I cant seem to get the ------- wastegate to manifold to seal, tried regular gaskets they burn out after a short time. bought sce copper gasket from summit, still have problem sealing, so I douldle them up it seals now, but I cant keep the bolts in, I drove for 10 miles and the bolts come loose, retighten them the keep comming loose, Ive been having this problem for a while, boost falling off because its not sealing.
so I am thinking of welding the wastegate to the manifold, blox manifold and tial wastegate, 2 different materials. tial is cast stainless steel and blox is some different type of cast iron than the regular ----. will a regular mig welder do this, clean, crack and leak free?

Re: welding
Try long bolts so you can put nuts on the back, lock washers, and locktite. If that doesn't work, you could always use the copper washers, but tack the flanges together in places where you can easily grind them off if you have to one day.

Re: welding
well 2 experienced welders, so should I just drill through the holes and put nuts and washers on the back from the inside? what if these come loose? turbo is fucked. I though I was gonna keep this blox manifold for a while but I guess its time to get an inline pro

Re: welding
If you're threading the bolts into tapped holes, just get longer bolts so they stick out the back, and put a lock washer and a nut on them. If you can get at it easily down the road, you could even tack the nut and bolt so that they can't come loose.

Re: welding
since this ia blox manifold, which is very similar to the DRAG and RV-hard, you cant put anything on the back, i think the problem is you are using metals from 2 different sides of the spectrum and they are heating and cooling(expanding and contracting) at 2 different rates.
what i would do, i get some studs and stud the manifold, ---- if you have to drop freaking JB weldin there and thread them down in, although i am reall not sure if JB will hold up to cast heat.
if it is studded with some grade 8 studs and them put the gate on with some copper seal use some lock washers on the top and you SHOULD be good to go.
i think the size is M8x1.25 for that bolt/stud

Re: welding
I use lock washers. they holes are not drill all the way through so its not gonna work with a nut.
the reason why I like cast mifolds better than fabricated manifolds is that they last longer, and everyone want too much money for the tubular manifolds, I am in Germany so there arent any resources to do it on my own, and I dont want to make a mani with my flux mig. so cast iron looks more natural and gets the job done. in this case maybe not
