rb 30 & rb 26 oil restrictors

[williamsf1]

ok for those that want to know I have just fitted a performance metal-craft RB26 cam cover baffle, and it seems to be doing the job nicely! basically stops all that oil sloshing out of my catch can pipes and all over the engine bay!

After spitting out a heap of oil on the dyno at the weekend, i cleaned the catch can out to see how quickly it will fill up. After several repeated 6500 - 7000rpm, 8psi runs, not one drop of oil is in the can now.

I remember someone posting the oil level can have an effect on blow-by. The level was spot on the high mark before the dyno, and now it is 2-3mm below. So maybe it's just the crank throwing up oil at high rpm. Now that the oil level is slightly lower, the crank misses the oil and none is thrown up.

Feasible?

will blocking off one of the oil feed affect oil pressure much?

Is the external diameter of the oil restrictors the same across all RB series engines? The Tomei site states the 1.5mm restrictors are for the RB26. Will these also fit an RB30?

use a high torque drill and go real slow with a nice sharp drill bit and descent pressure and take big bits of swarf...and tap with nevercease/grease on the tap to pick up any swarf from cutting thread.

bolt/screw size - pitch = drill size as a general rule of thumb. Might help.

120 degres for drill bit also...put two nuts together face to face and that angle will be about 120 degrees. Few little engineering tricks if ya stuck.
