About the drainage...
I came up with the vacuum idea because there is no room under or below the breather tank for a petcock or for holding a cup under the drain. Hence the approach to empty it from the top, using readily available engine vacuum. |

No, there will be a section of rubber hose (2 hoses) to connect the hard lines to the breather tank ports.
Re: vacuum, no need to concern about fumes, as I would think you would do this on cold oil. |

Today's plan was getting everything done and visiting the aluminum welding shop.
I just took my sweet time instead. Welding and powdercoating will have to be on Wednesday, or Thursday even. (I really do not want to haul everything on my bike, so I will have to borrow my sister's car for a day.) But, there was progress: https://imagizer.imageshack.com/v2/1...923/UcGtrm.jpg https://imagizer.imageshack.com/v2/1...921/gZuWkw.jpg Hardline "legs" are done. I also made some spacer clamps to hold things in place. https://imagizer.imageshack.com/v2/1...924/Sjtadu.jpg All the bare aluminum will be black like the VC. I am pretty satisfied with how it looks so far. |
|
I also drilled and tapped the 30x10 aluminum bars I will be lining the inside of the tank.
That took longer than I expected. https://imagizer.imageshack.com/v2/1...923/zFlDPZ.jpg https://imagizer.imageshack.com/v2/1...921/vHPpDa.jpg More to come... |

Are you opening up the internal passages in the valve cover?
I had already enlarged the "hole" between the center section and the hotside baffle. Is there more to be opened up? I guess the best thing to do would be to take a picture of the bottom side of the VC, and we can take it from there... |

Yes, center to hotside orifice.
Good work. |
Progress...
Here's a trick I use to mark screw/bolt hole locations - I have used this method on a ton of things from brake caliper adapters to miscellaneous blanking plates... Get proper size screws/bolts for the job and cut the heads off.. https://imagizer.imageshack.com/v2/xq90/923/Irc8mn.jpg https://imagizer.imageshack.com/v2/xq90/921/kho1IC.jpg Then use the grinder wheel to sharpen the cut tips to a point. I don't have a lathe, so a cheap drill in a vise works. Then, thread the screws/bolts in their holes... https://imagizer.imageshack.com/v2/xq90/923/E5Uekd.jpg A small hammer comes in very handy here... Hold the cover in place, and lightly tap on each pointy stud... https://imagizer.imageshack.com/v2/xq90/921/zCXcXw.jpg All your screw holes are belong to us! |
That was my PSA for the day...
Anyway. I briefly considered drilling a bunch of holes on a piece of aluminum sheet to hold the steel wool, then I remembered I actually have some wire mesh tucked away somewhere. (Left over from my vacuform project) So I used that instead... https://imagizer.imageshack.com/v2/xq90/923/N0N2oV.jpg And, this is how it will sit in the breather tank... https://imagizer.imageshack.com/v2/xq90/922/0XHF2v.jpg |
Inlet tubes from the engine will extend past the oil trap, and the steel wool will be in this section.
(Not the actual steel wool I will be using, that gunky stuff is just modeling for the photo) https://imagizer.imageshack.com/v2/xq90/922/HZJ05D.jpg |
The two inlet pipes will be welded in place.
I know I was talking about using grommets for them, but they will not move around if they are welded. https://imagizer.imageshack.com/v2/xq90/921/B6ZdEA.jpg The only thing left to do is the drain doodad I had mentioned earlier. It will be welded to the lid, and come up with it when I open it up. That's pretty much it. I just need to get it welded and smooth the edges. |
Oh, and there is the sight glass, too.
I reinforced the 2 mm aluminum wall with a piece of 3 mm thick aluminum so the 1/8 npt fittings would have some meat to bite. https://imagizer.imageshack.com/v2/xq90/923/HV79PI.jpg I am not concerned about cleaning off all the sharpie markings. Media blasting before powdercoating will take care of that. |

Cool to see the custom fab work and creativity. Where did you hide the oil cooler? A bunch of us sure know the pain of getting that “one more thing” under the hood. I put a VTA catch can about where you have your BOV but did the IC piping down and around.

I do not have an oil cooler, just the factory "warmer" on the block. The hood vent does wonders even with two turbos adding heat to the oil. The highest oil temp I have seen with the current setup is 102 C, on a very hot day. As soon as I get up to speed, temps go down quite a bit. |

I really can't remember. It was a French brand.
