Sarah Palin's got your back



If you've got the stones to maybe ruin a block, go for it. I however will not be pioneering this technique.

Alternately: who has a broke *** BP block to cut up and show us whats inside?

All I can say is my current system is the best I have come up with yet at solving the breather issues with a 350+ HP track Miata that turns righteously quick lap times in a somewhat reliable and repeated manner. It has a hole drilled in the block to aid the breather system.

Would you happen to have pics?

I didn't know that you were running a slash cut. Do you ever have smokey exhaust because of the slash cut? I do occasionally :(

And by "technically not legal" you mean "explicitly banned in its own rule", right?

When I ran the vent line from the intake side PCV port it was a disaster after hard left hand turns. Blocked that off and it was fine. I know there is still some oil getting sucked out the tailpipe because of the residue that collects in the hose going back to the exhaust but I donít have oil smoke clouds following me around. Smoke problems I have had after this install were from failed o2 and running too rich. I safety wise or environmentally donít see the difference between vent to atmosphere and vent to atmosphere out the tailpipe. For some reason the people making competition rules donít like it though.

Hey Bob, I don't mean to be "that guy" but are there 3 spacers under your oil filter? Looks like filter > mocal thermostat spacer > gauge and turbo feed spacer > OEM heat exchanger > block

Mazda originally designed the B6-T with a Breather port in the block I have talked to some European Rally guys who ran the cars in factory support trim and said they came with a breather system with an oil separator that drained back into the bottom of the oil pan. I have never seen the system installed myself but if you had a US spec GTX it came with the breather and the return port blocked off as shown below.

The guys road racing older GT-Rs with RB26's use a large diameter hose between the top end of the block and the back of the head to allow the gasses from blowby and pumping pulses to pass more readily to the valve cover area. The oil draining back to the pan is fighting the gasses coming upward from the other direction through the same small area and at high RPMs and high boost there is a lot of both. Increasing the flow area between the top and bottom of the engine reduces the speed of the gasses and creates less oil vapor as the two pass each other. Everything gets where it is going with less impediments.

Damn, you beat me to it. I was gonna run out and snap a picture of those fittings on my b6t.

i feel like maybe "you" shouldn't drill a hole in your block, id personally weld a bung to the valve cover if your intention is to avoid blow by... but realistically if u really need to in order to run 20+PSI id avoid DIY

I run 40psi and two -12 fittings do the trick well enough.

Hondas/evos etc that run high boost frequently have 4x -8 fittings...

How much boost will you run?

A single -12 was fine for me at 25psi.

I'm not as familiar with miatas, but id never intend on drilling a hole in a block, build vehicles so you can remove modifications without preeminently damaging your car.

if u ever wanna pull your turbo id prefer to just swap a stock valve cover instead

If you turbo as well as you grammar, you are already preeminently damaging your car.

There is always a point of no return. For me it was the third heater core that leaked. Now, my car will never return to a stock coolant system. That's just one example on my personal car.

well i guess it reflects the fact that i never have 'turbo'ed" a car. hence NOOBIZM...

It all depends how far your willing to go, what i do know is simplicity in turn has always brought reliability. If you decide to drill into your block id recommend having a machine shop handle it.
