Billet 7075 vented oil caps

[Hal]

Finally made up some more.

Turned out pretty good for being done on a home made CNC mill.

Figured out a way to reduce the profile so the next group will be a little shorter.

Are these better then Welding fittings right to the valve cover??

[snowborder714]

I guess some people haven't figured it out yet. This is a forum. There should be no mention of pricing, availability, etc., which Hal hasn't said. Either look in the vendor forums, the classifieds, or send him a PM if you want to ask these questions.

That's awesome!!! Home made CNC mill eh? curious how that came about, looks great! ill PM you for more info.

[PieEyedPiper]

These look fantastic! How tall are the currently and what is the expected height on newer parts?
I'm also curious about your homemade CNC! I used to work on a pro-lite, small but very capable... but also 25k.

The current height is 1.3 inches above the valve cover measured at the top of flange where the oil cap sits. The new caps are 1 inch.

The 1.3 height has been proven to clear the hood on the 1g, 2g and 4g63 powered EVO's.

PM me please

Look nice, do you have any pictures of it installed on a valve cover?

See my uploaded photos (profile)

Wow, this is a pretty cool idea. A very practical alternative to welding AN fittings to the VC, but how do they compare?

[nitroazz]

If someone would like to explain to me how this works that would be great. I am sure I am not the only one here with these questions.

[Lou98GSX]

the only problem i see with that is that there isn't a baffle under the oil cap so you might be pushing a little more oil than with the other set up. i might be wrong but has it been tested. it does look pretty cool though

Look again, there is a baffle as well as a splash shield as part of the cap assembly.

Tested? These things have been in use since mid 2009.

That's pretty damn slick.

[stukyl28]

So is there an advantage to using this over welding in fittings to the valve cover? Besides the sheer fact you don't had to weld anything.

[jpmxrider489]

I'm also curious as to is this a advanced to welding fitings? Normally each fitting as its own route on where the oil comes to where this it's all being forced out?

Why does the installed one in your photo only have one outlet and these have two? Old design?

Because I felt I only needed one fitting on mine.

Put me down as #3 that wants to know about this.

Come on Hal... annie up. Give us the goods on this homemade CNC machine.

[Hal]

Ok

It's a bench top mill from harbor freight.

All of the lead screws were replaced with ball screws and the cranks replaced with stepper motors (2000 steps per rpm) reduced for a final drive of 6:1

Resolution works out to be roughly 2000 steps per mm

It uses Mach3 mill running on the pc and drives the steppers thru a geko 4 axis interface

The pc controls the table (x/y axis), the tool (z axis and rpm) along with an optional rotory table (a axis)

The conversion was all done by me (motor mounts, ball screw adaptation, etc)

In addition I also converted my bench top lathe to CNC which was a piece of cake compared to the mill.

These days you can buy turn key kits for this conversion.

Annie? Annie bo bannie? Do you mean anti-up? Just reminded me of this.

Very cool.

How is the build quality of the HF mill? How do you think it would compare to this one?

That's got 25% more Y axis travel than mine.

But the largest part you can make is axis travel (5") - tool dia.

Keep that in mind.

If I had to do it over again I would have just bought a knee mill.

Can't wait to get home to my single outlet cap.

I'm not the greatest welder and with a check valve this will take the place of my stock PCV valve.

Another reason I went with this is a friend with a built 2.0, 5858 car was popping the dipstick and pushing oil pretty good he tapped his VC with a 3/8" tap in a risky manner, but basically it worked great so I figured a single -10an (5/8") would work good for me for a long time.

Thanks again

If you go onto Search Instructables
there are several variations of DIY CNC mills using alot of recycled parts to make a dirt cheap version.
Your imagination and wallet are the only thing holding you back.

[RedTalonTsi]

Do you have to disconnect the fittings in order to remove the oil cap?
