Default fabricators/welders need some ideas/help

well as you can see i have my bov placed right after my blower and i have been getting oil from the blower everywhere since a little comes out the discharge side and out of the dam filter i have ( its normal) it all just goes straight out the dam bov and im want to make the bov outlet go back to the piping of the intake pre blower. its better than me having a dam mess to deal with.

here are some pics of what im talking about





you can see the little black 1' cover i have on the pre blower intake wiht the hose clamp on it from the original **** bov.

im thinking of cutting off this bottom part on the pre blower intake since its only a 1' od pipe and welding on a 1 3/4( size of the bov outlet) aluminum pipe on it and then fab up a 1 3/4 tube with some bends from a 1 3/4 mandrel bent steel tube and then using some silicone couplings to connect it.

to any fabricators out there i need to know can you weld cast aluminum?

and any other ideas ?

Cast aluminum welds just like any other aluminum. I preheat mine with a torch, then use a TIG welder. I dont have a high frequency box, so all my welds are scratch start- but they come out nice still.

Pre heat it with a rose bud and then TIG it.

I would cut the BOV off the pipe and rotate it (if possible) and aim it at the intake pipe and reweld. Then weld the proper size tube to the the inlet elbow, straight shot and only need some hose and two clamps.

Welding cast aluminum can be a breeze or a real pain in the ***. It really depends on the quality of aluminum. You will need a TIG machine, and simple propane torch to pre heat the aluminum, and get after it. LOL

Another thing with welding aluminum, clean it, then clean it again. And do not use a steel brush from other projects for the cleaning, use an aluminum brush.

question.... why is there oil coming from the blower is that noraml.?

thanks rick, thats what my plan was , i just forgot to mention i was going to re align the bov.

the blower has been rebuilt just now and still has a small amount of oil coming from the discharge. i have seen alot of forced induction stuff do this. turbos included its not alot of oil its just enough to glaze the surface around the filter like under the hood.

Why not use 2 of these http://store.summitracing.com/partde...5&autoview=sku and weld them to the ends of the custom bent steel pipe to get the BOV where you need it and leave the mount on the intake tubing where it is that way your welding steal not alum.

I have never had any problem welding new cast aluminum. If I were you, I would pipe it up the *** of the guy that rebuilt the blower, that way you would keep the oil out of the combustion chambers.

because all the piping is aluminum. and i already have the parts welded to the post blower pipe. and imo it doesent need to be moved it just needs to be re clocked.

All of this is cast aluminum, and this was the first time I tried welding any aluminum.



I used all cast pieces because they're thick and I wanted to keep the blower noise to a minumim. The trick is to first clean everything well (I used a residue-free brake cleaner) then preheat - like has already been said.
