Turbo-fold gasket leak, German FAIL

switlikbob · 03-12-2019, 07:37 AM

When my turbofold was removed for the upgraded turbo installation, I found that my turbofold was NOT installed correctly at the factory.

I contacted BMW NA for an explanation. They could care less.

I'm writing this post to make others aware that their turbofold gasket may fail prematurely because of this installation issue. Cylinder #1 is was affected.

So what is the solution? To re-torque the turbofold to the factory specs?!

Thanks for the heads -up.
Any thoughts on cause of failure ?
Material defect, manufacturing issue, installation issue (torque, misalignment, etc)?

I think the answer is simple. There is a method to tightening the turbofold down, which is very German. By that I mean, it's similar to tightening down head bolts, LOL. I can only assume that the lazy BMW tech did not follow the procedure properly. The gaskets are kind of strange. Here's all the info you ever wanted: https://www.newtis.info/tisv2/a/en/f...-with-control/

I haven't seen a pattern like that before. Generally head bolts work from the inside out. This is more like a figure 8.

Keep in mind every time you remove turbofold, the gasket cannot be reused and needs to be replaced.

These sealing parts are supposed to work with the hottest part of the car and the thermal deformation is permanent.

That gasket did it's job. I see no sign of an actual leak.

What pictures are you looking at? It's just cylinder #1 that leaked.

Yes, this is absolutely true. I've purchased multiple sets of these.

I was just stating that it's complex procedure, that you have to do multiple times to get it right.
