Dorman 667-520 Turbo Oil Return Line Compatible with Select Buick/Chevrolet Models (OE FIX)

Gute Ware

About a year and a half ago I replaced the turbo on our 2018 Buick Encore and when doing that job the factory turbo oil drain tube (which was plastic) crumbled into pieces during uninstallation. I bought another factory (plastic) oil drain tube and installed it with the new turbo.Just last week I noticed some smoke coming from beneath my hood and investigated... that plastic oil drain tube had cracked and was letting oil spill down onto the exhaust and get blown all over the side of the engine as well. It was just a year and a half old! After looking around for something better than the plastic tube I found this Dorman steel tube and knew this was the solution.As far as installation goes it was a bit tougher to get aligned than the plastic tube (kind-of to be expected since the plastic tube is more flexible than the metal one). I had to use some long-handled channel locks to grip the turbo side of the tube and twist/align it to the bolt holes. Since the steel used for the tube is fairly thick this took a bit of effort and time.The quality of the product is what I would expect from Dorman. They've been around for a very long time and I've used their products on more than a few vehicles (in fact, the new turbo I installed on this car was made by Dorman, and it's been perfect so far). The oil pan side of the tube is thick steel and has dual o-rings, one being a high-temperature o-ring. The "flexible" part of the tube is quite heavy duty steel and tough to bend... even though it looks (from the pictures) as if it would be soft and easy to manipulate. The turbo side of the tube is also steel and comes with a steel plate gasket. As far as quality goes, I would give this product a 10/10.If you have a GM vehicle with a 1.4l turbo "Eco Tec", and you need a new turbo oil drain tube... I would highly suggest you get this one. Avoid those plastic units... if I hadn't caught this problem early, I could have dumped all my oil on the road and had MUCH bigger problems! I can easily see this unit lasting the entire life of the vehicle!

Fit perfect and much more robust than the cheap plastic OEM one! When you change your turbo, for sure change to this upgraded stainless steel tube. You will more than likely break the plastic one trying to remove it, but his one won’t break if you need to remove it again. Great part!

Great replacement for the OEM part, works well, no leaks

Part for perfectly and was easy to install
