Hello

So i have a small question, the oil feed line started leaking in my 2.0, and as usually I'm already waiting 2 weeks for the dealer to get me an OEM replacement (This is official Hyundai dealership - and i don't think they will get me anything)

So, i took off the damaged feed line, cut it open and as it seems the internal diameters are:

- Steel tube 4.5mm ~5 mm
- Ruber part of the line ~6.2 mm

Now, i CAN order a custom made line to fit, with PTFE core and steel braiding, but they only offer 3.5 mm internal diameter, so it may be a bit more restrictive than stock 5/6mm

Would that be a problem four our turbo?
Anyone runs smaller oil feed lines or is this a no no?

I won’t speak to specifics, but in general, logic suggests that restricting oil flow to a turbo would be a no-no.

If you’re dealer can’t find or get you the correct part, it’s probably time to try another dealer. There are a handful on the internet that will have vastly better knowledge and inventories to get you taken care of.

On stock we don't have any restrictions correct ?
As i said stock line is 4.5~5 mm internally in the narrowest point, I'm wondering if switching to 3.5 mm would hurt that turbo.

I've been using the ATP oil line for 6 years now. I did change out the banjo bolt to a regular AN type fitting at the oil filter adapter and a little bit longer line. But that kit will work. Just connect the banjo bolt end first.

Thank you for the info

Well it seem sthe official Hyundai dealership in Poland finally got the part for me (2 weeks time)
So i will install OEM, although as it seems just crimping your won custom PTFE / steel braided line would actually be cheaper and better :)

Any way thanks for the responses

I ended up stripping the hole where the banjo bolt threads at the oil filter adapter as it got removed so many times while I did oil cooler work. But I like it much better as it now has a 90* 4an flare x 1/4" NPTm on there. The 1/4" NPT threads are easy to tap on the aluminum. Just don't tap too deep. Just takes a piece with the another flare for the turbo end reducer fitting. My line is 24" and maybe an inch too long.



Since this pic I have also added a 30" line to remote mount the yellow oil pressure sender as it was having reliability issues and was difficult to get to. Also isolates it from vibration.
