head to turbo oil line on a evo3 16g?

Justin (our resident turbo expert here on DSMTUNERS) has made it clear to me by reading through his posts that it is a BAD idea to run with a 16g turbo off of the OFH, mainly due to the MUCH higher oil pressure that comes from there. There are basically no benefits to running it off of that line. The oil in the head is just fine, because the cams' only lubricant is that oil, otherwise it is straighton metal to metal. I have a B16g running a stainless line from the head. I wouldn't chance it from the OFH, it is not worth the risk regardless if you use a restrictor or not. Good luck.
 
I run my 16g from the head with a Earl's inline filter in between. The line is -4AN SS with a banjo bolt style fittings on both ends of the line. My turbo blew smoke and had slower spool when coming from the OFH. I don't have any balance shafts and my OFH is not ported so I bet that played a role in the over oiling problem.
 
didnt know that, disregard my post

Don't sweat it man, there was no bad info there, because that is the general idea behind it. :cool:The only problem is the pressure, but many have run them fine with restrictors, other have done fine without. Unfortunately, many have suffered the consequences from the OFH location.

If I were you though, I might think about switching back up to the head feed to help lengthen the life of the turbo. Otherwise, as long as you have the right restrictor in, you most likely will be fine.

Unrestricted from the filter housing will absolutely cause a premature failure in any TD05H turbo as the filter housing can provide roughly twice the maximum recommended oil pressure to the turbo.

If you're sourcing a MHI turbo unrestricted from the filter housing, you're on borrowed time....some guys have oil running into the exhaust in as little as 500 miles with a new turbo; some have reported years of use without problem, but the bottom line is why risk it. The oil at the filter housing is no cleaner than the oil at the head, but the oil at the head is of lower pressure.
 
I would run it from the head. You can find a feed line kit anywhere that sells parts. You can look on our supporting vendors.

They make a feedline kit for the 20g aswell. So I would assume that running from the head would work. But I dont know much about 20g. Im sure justin would chime in here. You can look it up.
 
If it helps i have been running a 20g and i used the stock oil feed line. From the head to the turbo.. i think thats the way to go.
 
Ok thanks guys. Im currently running it from the OFH and I believe that is what is causing my car to smoke a little when I get on the throttle (4k rpm +). I believe that the oil pressure is pushing some oil through the turbo seal.
I dont have a OPG yet so I dont have a clue that the oil pressure is.
I already ordered the head to turbo line fron jnzracing or some site like that and will probably instal it today.
I will updade the post later to say wether the line was the solution for the smoking problem im having.

My 16g turbo has only aroung 5k miles so I dont think it needs a rebuild yet but I might since its only like $50 and some piece of mind.
 
I run a 20g from the oil filter housing. I ended up using a holley .075 carb jet. They are 1/4x28 thread. Just drill and tap the fitting on your oil line and grind about half of the top of the jet off leaving just enough to where you can still screw it into the fitting. The trick to getting it to fit really nice is drilling out for the threaded part of the jet, and then drilling for the top of the jet to fit snug. The more you can grind off the better, because you need to be able to thread your male fitting in all the way. Works perfect and if you need to change jets for different pressures it is as easy as screwing in a new jet or you can drill out the jet if you just are going bigger.

BTW, i like just going form the head with stock oil feed line as well. the reason I went through all this trouble was whoever owned my car before me stripped the fck out of the heads feed. So I had a bad leak from there when I bought it.

Sorry for the noob question, I am too getting ready to install my big 16g turbo. By reading lots of thread on it. I may want to run off the head, but what is the restrictor? It seem like most kit come with the line to the ofh...
 
i am also new to working on cars and doing my first turbo installation (16g with installation kit from extemepsi). i have everything installed on my 1996 talon tsi, but i want to make sure my oil feed line is in the correct place (note..i have not started my car until i know everything is in proper places). one side has an eye bolt and the other is an 90 degree banjo bolt. the banjo bolt is installed on the turbo and the eye bolt is on the head (temporary). if you were looking from the front of my car in the engine, it is located to the top left side of the head right below the valve cover. i put 2 crush washers in between the bolt(14mm), but realized the bolt was too short so i got a longer bolt that works perfetly. is this the proper place? it doesnt look right because i dont see how oil can get to the eye bolt. directions on installing the oil feed line has confused me more than ever with all the possible ways. i was also thinking that i have the line backwards. if so, do i have to put the banjo bolt on the head and the eye bolt on the turbo? what hardware would i need to get to make this happen? such as crush washers, banjo bolts, teflon or anything for a leak free relaible fitting.

well i found the problem to why i am leaking through my return line. i used the same oem gaskets and i didnt replace them with the stock return line oem gaskets. im gonna get them once i have the time to jack the car up and fix my oil pan plug LOL. for the return line, i used the oil banjo bolt with a copper crush washer (i am not sure what the torque speca are, but i tightened it to around 34lbs). at first it was leak free under 18psi, about 6 months later (currently) i see evidence of a extremely small leak on the return line from the head (about a drop every 1,000 miles) the answer is YES!, you can install the feed line from the turbo to the head efficiently! goodluck with your project and remember to replace EVERY gasket that deals with any lubricants or fluids when removing or replaceing parts!
