Mustardxf2 310 Posted July 10, 2017 I'm in need of a oil breather can for my crossflow and I've seen people with welded fittings on a Aussie speed cover, are they all made out of the same material mine looks to me like it would be a prick to weld.

ando76 4,354 Posted July 10, 2017 Yes they are all sand cast. They can be welded. You can expect some impurity in the weld due to the sand cast material but it comes up ok. 2 Mustardxf2 and Bigflop reacted to this Share this post Link to post Share on other sites

So any decent boily should be able to weld a fitting on to it then ahahSent from my Pixel XL using Tapatalk Share this post Link to post Share on other sites

ando76 4,354 Posted July 10, 2017 That's one of the 3 fittings I had welded on a customers rocker cover. I don't tig weld very well so I took it to a mate that does. Share this post Link to post Share on other sites
Mustardxf2 310 Posted July 10, 2017 Shit that's clean. Next question should I use one of the exsiting top holes and chance ruining the top of the cover or drill a new hole on the side, and benefit/disadvantage of it being top or bottom?Sent from my Pixel XL using Tapatalk Share this post Link to post Share on other sites
ando76 4,354 Posted July 11, 2017 That photo is of the balance tube fitting. It runs in the side. Bear in mind that you will need to clean the paint off to get a nice tig weld Share this post Link to post Share on other sites
scottly 475 Posted July 11, 2017 I'm pretty sure you can get bungs that use a thread and thin nut all you do is drill the hole slide the bung in, then the nut tightens from the inside of the rocker cover. But weld in is probably a better option Share this post Link to post Share on other sites
ando76 4,354 Posted July 11, 2017 The only downside of using a 'bulkhead' style fitting like you are referring to is the nut on the inside. I'd be worried about it coming loose. Bad things could happen if it did. That's why I have always welded mine. 3 Mustardxf2, scottly and Valvebouncer reacted to this Share this post Link to post Share on other sites
