Bolt size for oil return on turbo

[Dsmj89]

Anyone know the exact size of the oem bolts that connect the oil return line to the turbo ? It's for a 1g oil return to connect to a 16g. Thanks.

The small ones correct?

Why wouldn't you re-use the old ones

Thanks a lot snow. I just bought a m6x1.00x25 bolts for the line to oil pan and they came with washers as well, will that work ?

Dsm pwr - I would but i rather have everything fresh and new, if you go to my thread "new 95 gst" you will see that my turbo setup consists of all new parts, bolts, gaskets, lines so i'm trying to keep it that way .

The length should be fine.

What type of washers did you get? I probably would buy the OEM "gaskets" for the line to pan bolts as they are more of a crush washer than a regular washer. I also know this is a common leak point for a lot of people. And if you're doing it right, why not?

I guess your right since they cost almost next to nothing...

Snow - I got regular washers that already came with the bolt, it's those type of washers that come made for the bolt that can't come off whatsoever.

As for the line to turbo bolts, i just bought me 2 m8x1.25x16 bolts and they were too thick for the hole ? You sure it isn't a smaller size ? The oil line to pan bolts i bought seemed to thread in perfectly.

The correct size for the oil return to turbo bolts is M6x1.0x16 and these use lockwashers, NOT M8.
