BMW V8 dry sump from billet

AdeV:
Once I'd bandsawed off the disc, the tube was revealed:

Inset shows the faint line.

To see if I could move it, I stuck a piece of .625" rod in the other side of the hole & whacked it with a hammer a few times. It moved...:

But not all that much, really, and it'd really take a concerted effort to shift it. Dunno if it would grip better or worse as a solid piece...

Now, if only I could check it for oil-tightness...

Darren:
Could you make a flat plate with gasket and bolt it on?

A lid if you like :wave:

Divided he ad:
Ade,

I'd have a bit of all the methods above myself, the heat fit will work fine and loctite on the insert before you (now lets copy and paste this to get it correct...) "wallop it with the Plastic Hammer of Destiny" :lol: This'll give very good leak stopping potential. Leave it to cool naturally (save issues with steam being created if quenched and creating fissures etc, and you could afford a few hours on a project like this to make sure it's all in place before machining couldn't you?)

As for the fitting of the barded hose connectors. I'd use PTFE tape.(Still very oil leak stopping on a good thread)
They're the kind of bits to get knocked and snapped during maintenance and you'd find it a lot easier to get 'em out than if they were sealed in!

Oh and your C-o-C is exactly what I had envisioned :thumbup:

Loctite..... I'd go with what John said :lol: (is that the green or red stuff?)

Ralph.

AdeV:
Hi Ralph - great stuff, I'll do a heat fit combined with loctite, then :) I think it's the red stuff that's temperature tolerant; but, then, for all I know ALL loctite is red!

I like the PTFE tape idea for the hose barbs too, provided it'll stand up to the 150-200 degrees temperatures which may occur down there... if not, I can always loctite them in anyway. Once the sump is on & sorted, there shouldn't be much call to take it off anyway.

Ah, the Plastic Hammer of Destiny - a close ally of the Spanner o' Doom (seen recently near an angle plate) :D

Darren - can't use a lid I'm afraid, I need each pipe to be separate. Now, one way to do that (with lids) would be to mill out a step in front of each tube, so it looked a bit like a staircase; then cap off each individual tube. However, to my mind, that would look messy & botched - I'd like people to look at this sump & think "it must be a casting..."

John S: Perhaps you need a bigger hammer? :clap:

Anyway... no more sump work tonight; I was going to do some, then I thought I'd do 10 mins on another project. Measured three times, cut it wrong twice, gave up for the night, brain is clearly AWOL. Real work interferes for the next couple of nights, normal service should be resumed around Thursday. :thumbup:
