piece is crap. NVM

 

Needs a flare to push against doesn't it to seal?

 

being that it's sole purpose is to relieve pressure (air) and not fluid... I don't mind if it leaks or not. It only spits out tiny bits of oil when running, but TONS of air move out. If it didn't spit any oil, I'd just leave the bs hole open to vent. I have to use this and run to the can to keep the little bits of oil off the manifold.

 

I want to run a scavenging pump( smog or similar on my crank case so I figured that it would help. Are you on a stock frame set up ?

Good find. Have you tried using ptfe thread sealant to see if that keeps if from leaking?

I just use reg old teflon tape and it doesn't leak a bit. Even if it did, it would only be leaking more air escaped, which works for me.

 

Too bad for us that have deleted balance shafts we cant utilize the upper plugged off shaft area for some kind of "vent". That is a huge opening just being capped off from where the balance shaft was. Making some kind of fitting or vent with a baffle would be interesting, I think.

 

Funny thing.... I was just looking at venting the block of a 4g63/

They use this same vent, I just do not see how much CFM you will pass through that small cross section.

I tried to make one of those fittings work already too.... but my space issues make that one not possible either. I literally have less than 1" inch between the back of the runner on my manifold and the head of the original bolt. The trick was to find a fitting that 90* deg immediately that used the least amount of height possible. Again a funny thing is I almost said the hell with it because so many of the people I talked to said "how much pressure can you relieve through a 1/8th hole?"

Well, when I took the piece and could blow as hard as I could through it with no resistance...I knew it would be perfect. If it were having to move large amounts of fluid of any kind, obviously it would not be large enough. But air comes through in droves.

 

Well depending on your health, weather you smoke or not, your lung capacity is some where between 1 and 5 liters. The pressure you produce may reach as high as 15 psi.

Now with your engine spinning 6000 rpm, just how many liters of air and at what pressure are you trying to vent?

 

I just needed to vent whatever air I could from the bottom of the block instead of just the head. I already use two -10an fittings to a can off the head, but the pressure in the bottom of the block was enough to push oil back up my return line and smoke out the seals. However much has been vented was enough to stop my smoke, so it was perfect for me.

PS.... how are ya Dale lol. (It's Daniel)

This is pretty cool, did it solve your blowby /crankcase pressure buildup? If your manifold does allow a straight fitting would you suggest the stm balance shaft fitting becasue it is an fitting flanged? Your way uses a rubber hose on the end correct?

 

I'd much rather use silicone tuning than an any day. It's unecessary for the job and rubs, and generally fits like pooo. If this fitting took 10mm id vibrant hose id be all over it.
