Default Tapping for oil

I was reading somewhere that turbos do not need that much oil pressure. Is there any merit to this? I tapped my RS-T at the rear of the block, the secondary oil galley. How much pressure is coming from that spot? I had quite an oil leak that I could not pinpoint, could I have blown a seal with too much pressure?

Too late to ask now, but I was always wondering where the oil was coming from. There was always some dripping out of the intercooler whenever I took it off and held it upright.

Oh, and I had a hefty oil return into a tapped pan. No blockage there.

Yeah, you could have seeping past the seals. I was the one that made the post about the pressure situation. Take a look :

If you have oil inside your intercooler it's most likely blow-by and such from the valve train. When you pressurize your intake manifold and such you push oil back into the air take before the turbo, through the breather lines. That's why people run oil catch cans.

I had breathers and they weren't saturated.

yea the turbo doesnt need a lot of pressure i guess, oil is probably going past your seals i would guess, i think there is quite a bit of pressure coming off that second galley plug, because i just used a subaru plug with a couple adapters and one of the adapters split(i am assuming from the high pressure) and caused a leak. but when i put in the plug that came with the ludespeed kit there has been no problems, the difference is that the ludespeed plug had a significantly smaller hole, i talked to tom and he said that the hole shouldnt be any larger than .1" i believe it was, maybe even .01, anyone confirm? anyways i bet a restrictor would solve some of the pressure problems, maybe even the oil in the IC.

I used a plug with almost a 1/4" hole. I had another with a smaller hole but didn't use it.

I always had hesitation above 4 lbs of boost, maybe the problem was from oil getting thrown in the mix from the turbo. My solution was to get lower resistance plug wires and gap my plugs real small.

I'm having the same problem with mine... but then again my turbo has 200,000 miles on it without a rebuild. I have a TD04L to put on, I just need the time to do so... As long as it's done before the SEMA show, I'll be ok.

Right now I'm running a -4 oil feed line, maybe a -3 would be better?

I love that banana... no matter how many times I see it, the thing just makes me smile.
