Oil return feed line please help???

[rixcidia]

Hey guys so I'm trying to install my 16g tdo5h turbo but I noticed for the oil return line on the bottom the end that bolts up to my turbo is flanged different on my 2g its prob like that because I had a garret stock turbo on there before and it matches that but what oil return feed line do I need that will fit my 2g and have the right flange for the 16g evo I?? Would that be a 1g line that I would need or something different???

Rix,

Yes, a 1g line will work.

It should be the same flange. Your referring to your stock t25 by garret right? Did you purchase a new oil return line? Doing an upgrade on my friends 2g we took the t25 off and put in a small 16g and the ends were the same. Some pics would help.

 

[rixcidia]

Right on thanks for the quick reply I sure hope JNZ Tuning has them I'm not sure with the mitsubishi part number is but I could only find the 2g flanged style like I have on their site

Incorrect, the t25 bolt spacing is different.

Rix,

Take a die grinder and slot the bolt holes in the t25 drain line. It doesn't take much, and it will bolt right to the tdo5 turbo.

I would like to replace the oil line because I can't tell if the opening of the gasket lines up with that oil line and the turbo this is the flange style that's on my current 2g but I'd rather get the one that is ment for the tdoh5 turbos

Rix,

 

[bryanwheat]

IT will line up just fine, many people have done it. If you don't want to than just buy a 1g drain line.

 

[rixcidia]

Do you know what the mitsubishi part number is for the 1g line I can't seam to find it anywhere

And WOW those are expensive. I had no clue they were that much. Just like Bryan said, you can drill the bolt holes out a bit larger to make it fit the MHI turbo. Even if you had a shop use their drill press it would be cheaper than a 1g line. I drilled mine out and replaced the metal tube with Silicone hose.

The 2G drain has a bigger inside diameter than the 1G line. The 1G is prone to cracking at the flex section. Really is easy to make fit as Bryanwheat has mentioned.

1G vs 2G drain

But the 1G drain p/n is MD150523 cheapest at JNZ

*whoops too slow

**Believe it or not, don't forget to get some copper crush washers for the bolts that hold the return line to pan. Just was reading about it and that may be one reason why I was loosing oil there. I thought RTV was enough... Go figure

Thanks for the link I just went to my shop and found a 1g oil return line but I'm not sure if it's useable with these dents please let me know thanks here are some pics of it thanks,

Rix.

 

[bryanwheat]

I would not use that.

 

[rixcidia]

Really there's not crack on it at all I was hoping not to spend another 60 to buy one

When you go to tighten it down it will put stress on the flex joint which can cause it to fail because it is bent. Just modify the 2g drain. It will work just fine.

Well right now my 2g oil line just bolt up to the turbo looks like some one made the screw holes bigger but how can I ensure the gasket is properly seated to the 2g tube and not covering the drain hole a bit? See I used the paper gasket that Justin sent me when he sent my turbo back from the rebuild , I noticed the center hole on the gasket is slightly smaller but what I did was put copper spray on the gasket on both sides and when It felt tacky I stuck the gasket on the turbo bottom end first and lined it up with the screw hole and it stuck there and then I just moved the 2g oil return line end over were it thought it lined up and bolted the bolts because it already attached to the oil pan but my question is how do I know if that gasket is properly seated and the oil hole is not covered by the gasket or 2g oil return line?

Just lay the gasket on the turbo and line it up with the bolt holes, from there you will be able to see where it is sitting on the turbo. From there lay it on the drain line and line it up with the bolt holes and you will see where it is going to sit. It will be fine regardless.

i wouldnt use it.

Hey guys so I tryed to tighten the turbo oil return line on the turbo bottom side well I tryed to tighten the bolts to spec and the one bolt just spins any suggestions?

Most end up tapping the threads a size bigger. There is a nut welded on the inside of the pan that likes to strip out sometimes. When you tap the threads a size bigger, use a small telescoping magnet and fit it through the hole for the turbo drain and attach it to the tap once it comes through inside the pan. That way, it catches the metal shavings.

When done with that, make sure to use some copper crush washers on the bolts to seal things up. Along with some RTV on the threads

Hey there thanks for your reply but my oil Pan is ok and not affect its the bottom of the turbo where the oil return line bolts up that's where the bolt won't tighten,

Hmm considering the threads go pretty deep that seems hard to strip out. I don't believe the threads go into the turbo where the oil supply is, it should be dry sealed holes. I haven't had those strip out before. Have you pulled the bolts out to make sure they aren't the ones stripped? If it's still the holes that are stripped, you might have luck with chasing the threads with the correct tap

*By the way, which way did you end up facing the Japanese lettering on the gasket?

 

[Bud92gsx]

If your return leaks.I have two of them.

 

[rixcidia]

Ok thanks for the info ill pull the screws off in the morning and take a look as far as the turbo gasket I don't remember I think I put the flat side to the header, I think my oil return line it self is ok I was gonna buy a 1g oil line to match my turbo but it was sooo expensive so I ended up modified the screw holes,
