Ok boys im in need if some advice regarding my DIY oil seperator / catch can.
I put the filter in between the passinger side valve cover and the plenum. Did i do this right?

The IN side is toward the valve cover and the OUT side to the plenum. Is this correct?

Finally should i cap the bottom of the seperator? or leave it alone? I ask this because im getting a mild hissing noise.

I did a forum search but the threads i found didn't adress these ?'s thanks..

I know when I did mine certain separators would hiss I ended up with a Coleman. Did you remove the filter element from the inside of the separator? And yes your orintatation sounds correct

GTtony

no i didn't remove it. is there a benifit to doing that?

GTtony

where's Cliffy when i need him...?

BraMas

yes there is a benefit if you run synthetic oil it will not work properly.

Hissing almost always means a vacuum leak allowing unmetered air into the plenum--which is bad--do you have any photos of your project?

GTtony

Cliffyk: Not at this time, but i can assure you that the leak is coming from the bottom of the huskey filter. I can manipulate it by covering the oriface w/ my finger.

Here is a sku # its sold under at home depot. HDA70403AV or
SKU # 401910

Bramas: Ok so if i remove the filter element, what do i replace it with?

cliffyk

That's a drain valve normally held closed by air pressure, thing is that you are operating the unit on a vacuum line and the vacuum is sucking the valve open. It looks as though the nipple at the bottom is threaded, see if you can get a cap for it.

The filter is there to cause moisture in the compressed air to condense and drip into the bottle. Oil vapour is much more dense than water, it will likely work better used as a catch-can without the filter.

Mine does the same it only does it when I shut the car off.

I don't know what it is about the Huskey seperators but I had 2 of them on that would leak like yours. Switched to the Coleman brand and no problems. And the seperator will work just fine with out the filter element in it.
