2011 s63 oil pump chain excessive play

TTV8M · 11-09-2020, 04:31 PM

So in the process of tearing down this 2011 s63 motor, dropped the oil pan and it feels like too much play on the oil pump chain.

is there a tensioner for this, or could this chain have also stretched?

i hear others mentioning the timing chain likes to stretch on the N63/S63s

There is revised-updated oil pump for S63.
Mine was updated couple years ago under warranty.

Thanks, I will have to order a replacement.

Also, I found the tensioner for the oil chain.

How many miles is yours?

Before its too late, your s63 is NOT a tu. It does not have a physical tensioner. It uses bolt/spacer to extend the pump and chain. 10mm chain slack from side to side.

How did you get this done under a warranty? I've got 140k on mine currently and BMW's website doesn't show any open recalls and we got screwed out of the N63 Customer Care Package even though we share the same chain setup.

It's not a recall, had an extended warranty. It was suggestion from shop foreman, they were dropping pan because of sweaty pan gasket, covered by Bmw Canada.
I would guess they are aware of oil pump problem on numerous engines.
Btw that was 2 years ago.
