oil pressure limiter or regulator??
looking for something to slow the flow of oil to my turbo.....
im thinkin my high volume oil pump (GMPP pump) is pushing to much oil to the turbo and causing oil to seep out around the seals and then raw oil burns in the DP and exhaust = smoke smoke smoke.
thats my theory anyway.
its not the NEW oil return hose i have on from Jeff M
the engine is not burning the oil in the combustion process.
any thoughts??
i wanna keep the oil pump cause i really liked it in my N/A 3.1 and thus why i ordered one for the turbo engine.
so im looking for a possable solution
I thought all TGPs come with a hvop?
Oil/Fuel Restrictor....
The Honda guys have to use them sometimes on turbo swaps, its an Autometer part.....just a sec.......*puts on hold......bah bah bah.....bah bah bah.....* haha

Boom, there, something like that, we got one, and just drilled the hole larger
i see how that could work......

umm no.....
when you venture into new ground with mods and such you sometimes run into small little problems that need to be worked out and thats what this is.
glad yours is so perfect the way it is...as long as your happy :roll:
I also fail to see how this is a band-aid...
You do also realize these are used on Fuel and Nitrous right. This is a pretty common thing actually, it can't be much of a band-aid if they make parts for it.
I guess the "right" way to fix it is to just right an entirely new smaller oil line.
I did a few searches on yahoo and google and found some very good links and forums about the oil restrictors in turbo cars.
starting to think this is what my problem is :?
oil is entering the DP and due to heat its kinda "cooking" it all the way down the exhaust system and smoke and minimal raw oil is actually misting out the tail pipes when im in motion and on the gas.
don't wanna swap out the pump is my main thing here if i can find another solution.
Mine works good for now :roll: I had to spend a grand to get there. wont last long with compressor surge going on. I dont think restricting the oil or replacing the only stainless line on the whole car will help either. Maybe a gapless oil seal.
engine is fully rebuilt and has less than 5000 kms on it so far (still tuning and tweeking the ECM)
-New high volume GMPP oil pump
-Rebuilt Turbo with brand new center cartrage housing by www.cheapturbo.com
-Stock oil to turbo feed lines not sure the sizes
I sure hope the turbo seals are not outright blown due to the oil volume increases.... :(
from the descriptions i have read on this forum from Jim (IDBeast) it sounds like its quite easy for the oil to blow past the seals.....like when the oil return tube is restricted.
This is kind of interesting me. I know I have a high volume oil pump on my engine, plus the oil lines are all custom made and I have no oiling problem at all in this department.
How is your oil RETURN line? If the oil can't find a way out, its going to find the nearest gap to get out, usually into the compressor or turbine obviously. This is what seemed to be the problem on our last turbo project. The oil wasn't draining, so instead it was going out the compressor.
forgot to add
i have a brand new turbo to pan drain tube....in fact its from Jeff M when i got my Crossover from him....
i have had it off to inspect it and there is no obstructions in the return piping at all.

so they put em in mazdas? That makes me want one.
No seriously, I'm sending mine back to Garrett and make them put a FULL ball bearing(meaning both sides of the journal) on there and then I will get the restrictor thing you are talking about.
Is that why you guys are doing this mod?
also, I am thinking more about the way my car tilts when I park it because it needs to drain by gravity. it also has to have a steady slope down to the pan. And I used to not think how where I park my car its tilted down one way to the sewer drain.
info on my oil pump FYI
10051104 High Volume Oil Pump
This heavy-duty cast iron oil pump has longer gears than a production V6/60? oil pump. It has 25% more capacity than a standard pump, and is highly recommended for all off-highway V6/60? Chevrolets.
(color coded with a blue stripe) will produce approximately 70 psi oil pressure.
hmmmmm is 70 PSI lots? :oops:

Not really, I'm sure it will calm down after its warmed up. Dunno about the V6s, but the SBCs have always been known for low oil pressures so if it has an affect I dunno. However, over on the 60*V6 forums one guy thinks his high volume oil pump caused his engine failure, a couple main bearings were scored and some other stuff.
Oh yeah, and our '73 Trans-Am was pushing off the charts over 80psi before it warmed up, oh and this was with a bad thrust on the crank pushin it forward dumping oil out the rear-main seal.
How old is the turbo? Maybe the seals are just getting worn/weak is why it is burning the oil?

sorry I must be an idiot. Does this mean you have a ball bearing t-25?
Sort of an update:
I have sourced a local shop that can make me an new Stainless steel -3 AN = 3/16 line for my Turbo Oil Feed for the T25.
now for those who know the 3.1 Turbo (TGP) engine has a small SS flexable line about a foot long that then connects to a hard steel line that then goes to the turbo.
should i just replace the short SS flexline with the custom -3 AN and keep the hard line to the turbo?
or should i run a longer -3 AN flex SS line the whole way to the turbo?
any help is welcome
Dave

From what I remember, we used the SS lines all the way to the turbo. I know the stainless line is right on the turbo, and I'm pretty sure its connected right to the pickup. As we have lots of custom welding and stuff like that on it, you will find its a lot nicer and much less chances of problems that way. I have had 0 oiling problems since the engine was put it.
if you can, PM Mr. Hat on clubgp, he has a turbo 3800 in his 2001(?) GP. He had the same problem i believe with too much oil presure and smoking like crazy. I can't remember how he fixed it though....He should be able to help you.
well i just ordered this after some rave reviews on the turbo Honda forums, Turbo Dodge forums and DSM forums.
http://www.stealthmodeperformance.com/oil-res.shtml
going to run a new -3 AN SS line from the stock location beside the oil filter all the way to the turbo inlet.
replace the stock lines and using a "T" fitting use the above linked product in conjunction with a manual oil pressure gauge.
im 90% sure that will be the solution to this issue.

also my Dad has one a bit more heavy duty on his airplane with a russian 9 cyl S/C radial engine :lol:

how much is that runnin ya? if you don't mind. I haven't a clue what lines go for.
Well my Restrictor i listed above shipped out yesterday so hopefully next week i will get it in the mail.
GutlassSupreme: i never priced the lines out yet i just made a few calls and I now have a few places that can make me a hose.
i will post a total cost for this when its done, so far im in $14 US :wink:
Got it in the mail Friday before i left for Toronto
:D

UPDATE:
ok here is what im going to try first (under $20)
(http://i5.photobucket.com/albums/y160/Invasion1/mod2.jpg)
assembleed this to simply fit inline with the current stock lines so if it works no need to remove any of the stock equiptment. :wink:
going to try it tomorow
Installed today and it is just fits inline without issue between the SS flex line and the hard steel line.....any longer and there would have been some trouble fitting.
im going to try it tomorow after my Battery charges (had the doors open today working on another gadget that drained the battery) :oops:
Looking Good :wink:
With the Valve i can adjust the oil pressure and flow to the turbo to what ever i wish :D
problem seems to be solved and also my turbo seals don't seem to leak with the oil flow cut back using the valve.
just have to find a happy medium somewhere in between to low and to high.
anyway im pleased with the turnout so far :thumbsup:
