Garrett & Holset Turbo Users - Your Oil Drain May Be Too Small!

Dude that is brilliant! Now no one has to worry about a hose kinking on them. Awesome! It makes me want to redo my drain

 

That is a great write up

 

Since you're enlarging the hole on the return flange(oil pan side) you can just use a 1g return, right?

 

Nice work miguelmcv, this may be the best oil drain yet. I never found a flexible cummins hose so I just went with the solid drain they come with. Been working for 3 years no issues but this may be my next drain setup.

 

Sounds like more effort than doing a -12 AN drain welded to the pan and enlarging the hole. Like my writeup.

 

What's the inside diameter of yours, Kyle? That other way is good because its an oil drain meant for the Holsets.

 

Yea no more kink hose,

Nice some one liked it.

Thanks bro.

Nope, you can use just the 1g flung but you have to enlarge the hole as well to match the oil pan.
1g return line is to small compared to the holset line.

Yea I know what you mean when you say can't find the flex line.
I ordered one from the same site and they send me the hard line as well, but I call custumer service and they walk me to the right direction,.

The line I posted before in the site is the right line (21 inch flexible line).

Let us know how it comes out though when you do it.

 

The I'd is what ever mm -12 is. Here I'll measure.. and with AN you dont have to worry about failing gaskets at the oil pan.

Looks like 15.40mm is -12..... Maybe you got me beat there, i haven't had any problems though.

The 3\8 flange i use is 24mm and the -12 line could be bored out to be bigger if people wanted to do that as a sanity check toget the proper 19mm on both hard line sides, i also beveled the drain inlet.

 

Looks real good wes, Does it leak at all?

My other thought was isnt the 3/4 hose to big on the 2g return line?

I really like the idea of that flexible one from holset but trying to save as much money as possible right now and yours looks good!

 

I did about the same thing as wes, except I used a different flange on the turbo side which is 3/4" NPT instead of 1/2". It is odd because the style of turbo we have has an off center square port for the oil return which makes for extra modding, I ended up grinding down my flange a bit.

Hose nipple is a -12AN with a 3/4" NPT. I used 3/4" hose as well with a hacked 2G drain. It had to be clearanced just like wes' because I have that same holset vband compressor cover so I ground it down:







Of course like I said, I didn't end up using the weld in bung as pictured.

 

Just thought I would share my setup. It is a fairly cheap way to do it. It is a 2G oil drain to the pan ( I just ported the Oil Pain to match ). Then I got a flange and welded a 3/4" stainless steel tube to it at an angle and coupled the two together with aeroquip hose and gates power grip. Total cost is about $40.

 

Here's my drain setup for my TL HX35/40 bolted to a Redjack manifold.

 

^exactally what i do.

 

That's a 10an drain right Laser90?

 

-12 I got the idea from this video. I used a 30 off the turbo and a 45 off the pan.

-10 is not sufficient.

 

Thanks Laser90 for the video, I saw I think when it first came out haha.

Yes Kyle I know I'm running a 12an setup.

 

Where did you get the flange fitting to the turbo? I have the flange from the ExtremePSI kit that accepts -10 but I dont know if it will accept -12. Thanks.

 

On the HX52 I run a -10 drain with a -4 feed from the OFH.. as do many others. I also measure my feed and crankcase pressure. It's right on the money at cold start, and rises ~8psi/1000rpm til about 75psi and stays there, which is exactly within the requirements per the service manual.

Have you actually checked your feed pressure or crankcase pressure?

 

Never mind, don't know how I missed this. Awesome!

 

Exactally what i used on my writeup for holset drains. Even linked it too

 

I know I must have missed it, but what size oil restrictor is needed for a hx40 that's being fed from the OFH?

my oil pressure is sky high and dont want to over-oil my freshly rebuilt turbo and ruin it.

 

Different for everyone. Measure your pressure first and go from there. Taking someones advice of "0.x worked fer me!" could very well lead to starving your turbo which is operating on a different system, under different circumstances.

 

Did you not search AT ALL? Or even read this thread? "Must have missed it" HA! Bullshit
