    I am finishing up my build and finally got the car to idle. My 7 blade hx35 is rebuilt. I have noticed oil in my intake pipe. Could this be to high of oil pressure? I will confirm pressures today and post back. I have a catch can properly set up as well.

    When you measure the pressure for the turbo, are you using a T fitting and leaving the sensor installed? Or just going of the pressure gauge (aftermarket) on the ofh?

    My pan has a -10 fitting welded to the pan. I know I need a -12. Without access to having this redone, is there a better way to do this. Could I run a restrictor to limit oil since the drain is to small? Maybe over oiling is reason for the oil in the pipe?

    Since diesel use different oil, should I change? Motor builder recommended 10w40. If there is something else I should use to help the turbo or overall I would be interested in it.

    I know these topics already have many threads. However, I appreciate the help.

    I think step 1 is to get the proper restrictor in the oil feed.
    See this thread. https://www.dsmtuners.com/threads/hx35-oil-restrictor-size-questions.510361/

    Justin hasn't been on in a while but I run full oil pressure to my HX40 from the OFH and he has always told me, "I don't know how you are feeding it, but it looks great on the inside". This is 90# cold start, settles to 16# hot idle and drain it WELL. WOT is around 60-70 Hot, I think. I don't monitor it under WOT usually.
    I checked my oil pressure by putting a tee in where my Earls in-line filter is and it is exactly the same as the motor is seeing.
    I run Rotella T4 and ad Rislone ZZDP additive to my oil and think it does an excellent job of not wearing on the thrust plate in the turbo and other high load areas in my motor. Has always worked for me. This topic is highly debated although in another thread on hear.

    -4an feed
    Oriface connected to ofh drilled out to .080"
    I'm seeing 8psi at idle fully warmed.
    I dont have much of idea on WOT pressure just yet.
    I have intents to drill orifice to .090"

    On a cold start I see around 60. While it warms up, it slowly settles around 25. Car doesnt have much time on it yet other than a handful of long idles. Glad to know that you confirmed that turbo pressure and motor pressure was the same. I dont think my oil in my pipe issue is due to overpressure since I am still under 72. The lines to my catch can were oil free as well as the line going to the intake pipe. The only thing I havent measured was crank case pressure. But the oil in the pipe was a little concerning. My old 20g at 30psi never had a oil issue. Neither did my small 16g at 24psi. But the car only say maybe 7psi at a failed drive.

    I know the oil topic has been covered everywhere. So are you using the 15w40? I would like to find a oil that is easy to find at the local walmart. The only 10w40 that I could find was mobil one high mileage stuff.

    In that thread, I am using the 3/8 90 degree fitting. But im not sure I need a restrictor if I am still in the specs.

    You don't need a restrictor for a Holset. Those diesel motors run high oil pressure. What you need is a drain of sufficient size to drain and not clog. USUALLY a 10an will work without pooling issues and if you had that, YOU'D KNOW IT. It would be slowing the turbo.
    I run 12an on one car and the best drain kit that I've found on the other from @MorrisonFab .
    You have a welded in bung but it should be ok at your pressures IMO.
    Maybe Mr Morrison will give his 2 cents.

    The turbo isnt smoking. But it really doesnt want to go over 7lb. I'm trying to diagnose wastegate stuff as well. However, still doesnt explain oil in my intake pipe. I'll see what I can come up with for a bigger drain. If I cant, I'll have to find a 10an adapter where the ID is bigger than some of the kits.

    Indeed. On my HX40, I run a -4 feed from the ofh. For the drain, I run a 1 inch drain. Totally unrestricted, no issues.

    I find it at a tractor or diesel store. My Orshellyns Farm and Home carrys it and my local WalMart does too. The WM also carries my Rislone ZZDP additive. :thumb:

    So upon further investigation, I believe I am fighting a small drain and high crankcase pressure. I measured my drain I had, was 12mm. I know holsets drain is 19mm. So made the pan and a new hose at 16mm. That's the best i was able to do. I noticed oil pressure was a little lower after this to.

    I noticed that oil is coming out my new filler cap as well as leaking out of my turbo feed line and filter. My catch can lines are not wet at all. I have a vibrant check valve in place of the pcv. Upon further reading maybe I should use the pcv and check valve. The pcv modulates while i go in and out of boost at low psi. But the check valve is a on or off thing. Thoughts on this theory? I want to try and running the pcv line and check valve to the catch can and plug the manifold to see if this helps at all.

    I run a check valve in the pcv line and the brake booster line so all they see is vacuum, always.

    Is that in place of the pcv or with? Or does it not matter. I'm going to do a leak down test as well.

    It is in between the intake nipple and the pcv valve to keep positive pressure out of my crankcase and not letting it even get to the pcv valve. The pcv valves don't do a very good job so I, along with a few others, put the one way check valves in both of those lines. So the answer is keep it (the pcv valve) and add the one way valve for added protection.
