On3 kit oil in exhaust

Hey guys. Got the car running with a pte 6765 journal bearing turbo and on3 piping. Just was making some tweaks at the exhaust shop today and noticed a bit of oil in the exhaust pipes. I am using the feed and drain that came with the on3 kit. What size is the feed line? -3 or -4? I am guessing that there is too much oil pressure and it's leaking by the seals? Center section is almost dead vertical, drain line is unblocked I ran 8 quarts through it to flush out the metal shavings after tapping the pan. Seemed to flow fine. Could it be my crankcase venting system? I have 3/8 vaccum lines run from both valve covers to a catch can with a breather. Does it need to be less restrictive? Is it possible that I just have too much oil pressure on the journal bearing and it's leaking by? Any help greatly appreciated
Thanks

You could have a number of issues. Personally 3/8 inch line from each valve cover is way too small. I would think a minimum of -10 (1/2 inch) or even better -12 (3/4 inch) from each valve cover is the way to go. I know some will disagree but I have seen too many cars use -8 from each valve cover to vent the crankcase and have issues.

Also make sure your turbo return is at least 3/8 inch, preferably 1/2 inch. Again I am sure I will get flack on this statement but I have seen small oil returns lead to issues. No one ever had a problem using an oil return or valve cover vent that was too big. Save yourself the headaches and use the big hoses.

Oh yeah, I run a journal bearing PT76 with -4 feed, no issue. From what I understand, you only have to restrict oil flow to the full ball bearing units.

Bad turbo?

big question is, are you sure its oil? i know how exhaust can carbon up, and when oe is running right, you get a bit of water in the exhaust , and sometimes it makes you think its oil...(just went thru that)

if its oil it should be like sticky ass left out maple syrup. or lots of oil, an smoking while driving, been blown oil seals. did you prime the turbo before starting the car for driving?

It was not real sticky and there is no smoke while driving. I will beef up the valve cover breathers. I think the on3 kit drain is 1/2 inch so that shouldn't be a problem. I don't know what you mean by prime the turbo before starting the car for driving. I cranked it a few times over without firing it the first time to get oil going in in the turbo if that's what you mean.

How likely is it that this is caused by my breather setup being inadequate? There is just a fine coating of oil inside the pipes, nothing major and it doesn't smoke. Just looked and I have a -4 feed and 5/8 drain but there is a stainless piece that makes a bend into the pan in the drain that is 1/2 inch stainless steel. Seems like it should work fine though. Could the breather restriction cause this amount of oil to accumulate in the exhaust? Should I run one of those smog pumps?

Turbo is clocked right. Center section is vertical. I called precision and the rep said the feed is fine as I assume it is a -4. Sorry about the title but people need to read before they do things.

You can get some minor oil seepage past the seal if you are beating on the car. I had that with my pt78. It wasn't smoking. From what precision and Frank at PSI explained the seal is like an oil ring and it doesn't prevent all oil from going through. If a little goes by I wouldn't lose sleep over it.

The oil feed supplied with each kit is 1/8" id and you should have a 5/8" drain which is more than enough. We never run restrictors on that and have never had any issues. Master power will not cover warranty work if we use anything different. They told us 1/2" min on the drain

Did you get the Precision turbo from us or did you get the kit less turbo and add it yourself? If you bought it from us, you have a 1 year warrranty and can have them check it out for you.

Sounds like slight, but normal blowbye. To be safe you can go ahead with the advice, but I'd take a step back.
