sourcing turbo oil from vvt
1 Attachment(s)
ive gone a less conventional route when it came to sourcing oil now im thinking i might regret it.
so i took it upon myself to source oil for my turbo from the little cast aluminum elbow that feeds the vvt on my engine. i wasnt lucky enough to have the oil feed on the exhaust side of the block and i diddnt want to go the sandwich plate route because i wanted to avoid having a hot braided steel oil line go across the trans and near all of my wiring and re-routed radiator hose. im trying to keep the engine bay as neat as possible, ive gone trough great lengths to remove any un necessary stuff from the engine bay i guess some would call it a wire tuck. here is what i have done. Attachment 187556 http://i1237.photobucket.com/albums/...c/DSCN0545.jpg im really new to all of this so please bare with me. ive rebuilt the bottom and top end (rings, bearings, valve seals, etc) and polished the head a bit. im confident ive done everything correctly. ill find out once i start her up but my main concerns are as follows. 1)is it possible that will i starve the vvt actuator or the turbo now that i have done this? the msm turbo does not utilize a restricter to feed the turbo its a pretty large opening on the original banjo bolt and im assuming it has been designed this way since its not a ball bearing trurbo its of the journal bearing kind. 2)if the answer to my first concern is a definite yes do you think it is a good idea to just bore out the hole on the banjo bolt that feeds the VVT on the side of the block to increase the amount of oil that can flow trough it. i know nothing about the characteristics of oil and how it behaives when forced to go trough small passages under the pressure that the oil pump produces. and i have no idea how much oil the vvt or the turbo really need once the engine is running. i appreciate any input and thanks sam |
Why not. I like it. Where do you get those little hose clamp things for cheap?
I think you'll be fine but let's here what the sexperts have to say. |

I source my oil cooler from the OEM oil pressure location, which is on that same line but tees a bit earlier than you did. The catch is that I run an .035" restrictor.

Why does everyone have a VVT engine but me?
BTW, you're going to wish you used that little turbo brace after the first few laps on the track. |
What turbo brace?

BTW, you're going to wish you used that little turbo brace after the first few laps on the track. the motor still isnt ready to go in i have to find a way to route coolant to and from the turbo and i have to see what im going to do about the heater-less coolant re route. thats what im working on now. |

im really just considering enlarging the hole in the banjo bolt, a little bigger couldn't hurt.

Give it a try, but be very, very wary of starving the #1 intake cam journal. As soon as you get things lit off, test out the VVT actuation in your ECU/VVT controller to make sure everything works. If the VVT works, everything is getting enough oil - if it's sluggish to advance the cam, I'd be worried about oil flow to the journal. e: I meant turbo, not oil cooler in my last post. |

With the .060" I pushed oil through the seals of the turbo, the .035" fixed that. So yes, mak,ing it larger can hurt. You should get a restricter.
the banjo bolt that fed the msm turbo from the factory has a .140"(3.56mm) hole in it. i wouldnt feel right installing a restricter. on the other hand the banjo that feeds the vvt has a .157"(3.94mm) i feel the logical thing to do is enlarge the vvt bajo since it will be feeding 2 things

I wouldn't bother - the line that brings the oil up probably isn't any larger anyway.

Correct. VVT oil supply only supplies VVT and the cams are fed by the oil hole in the head gasket. However I do think it's prudent to check the advance as Sav describes. This will suggest if the turbo is taking away too much flow from the VVT.

MSM's have a little metal plate that mounts from the bottom, left rusted bolt in that pic to the engine mount.
