My m5 has burger motorsport dct pan and only been there for 2 years with 6k miles but starting to leak, solution is to change gasket but that means 7 liter of oil at £20 a liter if I do not want to reuse mine

It is slow leak , I was thinking of putting high temp gasket sealent around the pan once dry. Is that doggy fix in your view?

Or drain oil, run it though mesh and reinstall it with new washer

I'll be brutally honest, why on earth would you drain the oil & not at the same time put fresh oil in?

Similar in vain to swapping worn tyres for part worn tyres. These cars don't take well to low cost maintenance if you want them to have a lengthy life.

Regular servicing with OEM or at least high quality consumables/components is paramount.

There is no fundamental reason why sealant won't work.

There are plenty of joints in various engines designed to use a liquid sealant instead of a gasket, which isn't the case here, but won't cause any damage.

But I worry that you still have the underlying problem, which will probably result in the oil finding a different way past the sealant.

What is a burger motorsport pan and does it use the OEM gasket or their own? The pan itself could be slightly warped or their gasket might not have the same flexibility as OEM so you could be back to square one quite quickly.

Have you increased the boost pressure on this engine? Although that shouldn't affect the DCT box, but is there anything that might be pressurising the oil within the DCT? That might be forcing it past the seals.

I would give the sealant a try.

If you replace the gasket, I would at least initially re-use the oil in case you didn't achieve a successful repair. You could replace later if it looks like you have got it to seal.

Is the DCT oil the BMW type or some sort of "upgraded" motorsport oil?

  • But before you do anything else you should re-torque the bolts, just to be sure that one hasn't lost any tension.
