mazworx block breather plug

[ultimohero]

I just finished assembly on my block and then the machine shop told me they forgot to put a part back in my block. It's the rear crankcase vent tube. FML. There's no way to get that back into the block without removing the head again.

mazworx sells a block off plug for it. I asked them how it worked and they said as long as you have good ventilation, it's fine to run. Has anyone ran one of these plugs or have any suggestion for me?

I ran one before, never had any issues. Just a little rtv on the orings n tap it in.

Any picture, I'm having trouble remembering what this part is and does.

Rear vent tube... hmmmm ???

Thanks that's what I needed to hear. I have a redtop btw. I'm gonna add another vent to the valve cover to run to the catch can.

It's the one under the exhaust manifold on the sr20det.

Errr... you mean the oil pan return from the pseudo air/oil separator (black box) ?

So why doesn't the machine shop pay for new head studs and head gasket and fix their own mistake? Do it right the first time. If it's their fault they should fix it.

I know they're not gonna do it. And it's their fault they didn't put it back on but I should have noticed it before assembly too.

Correct. But I don't have the black box or anything. When I got mine it was already gone.

just tap it and thread your own fitting on...its inconvenient but not impossible to do w/head on...

Actually I cut a "v" from the original fitting and got it to squeeze past the head on an angle. I grey rtv the hell out of it. And hopefully it will work.

that should work! I usually do a "ten pound test" and make sure it doesn't move with a little force...not to much tho lol

I let it sit for a couple of days. I'm gonna go give it a little wiggle in a few minutes. I think it's good. I need it to be otherwise I'm gonna be tapping it. I do not want to take the head off again.

You don't need to remove the head

Just tap the OEM fitting back into place, even with a smidge of sillicone to keep it 'secure'

The issue was the fitting was too tall. I couldn't get it past the head. So I ended up trimming it some
