I have my tranny out and need to replace the input shaft seal and am wondering if this is one of those seals where genuine BMW is recommended or is Corteco an acceptable alternative? Thanks...

Corteco is fine in this case. It's the pilot bearing that you want OE and the throw out you want OE or at least Sachs instead of LUK.
Corteco is factory for a number of important parts on our car.DD: /// 2011.5 Jerez/bamboo E90 M3 · DCT · Slicktop · Instagram

Remove the old seal with Special seal puller or use wood screw to extract it. Before you pull it, measure and note down how deep you need to install it.
for install/correct seating you need a special tool or make you one with something like a pipe.
If you or a friend have a 3d printer, life gets easy just print the tool your self. I always print these kind of tools, just for this worth to have a printer.…under construction.

I just DIYed this a few days ago. The replacement Corteco seal actually had a spring inside it whereas the original one didn’t. Nonetheless it seemed like a good replacement. A few notes:- If you use the wood screw extraction method, don’t drill too deep as there is a plastic clip right behind the seal you don’t want to damage.
- My measured install depth was 2.5mm
- A short segment of 1 1/2” sch40 PVC pipe works perfectly for tapping it in

Seal with a spring inside is rubber, while the one without spring is Teflon which is better. I'm surprised that Corteco seal in this case is not Teflon, as I just replace a 325i AUTO transmission torque convert seal and it's Teflon, so for the higher rpm M3 I would expect it's Teflon too.

I removed the filler plug today and no oil flowed out after changing the LT2 a month ago ( 1.7 Litres . I managed to get another 250 ML in,so i am quite certain it's the front seal now, Just looking at the TIS on smg removal , does anyone skip the intake manifold off step? Anyone got a list of parts needed, common breakages
Also what time frame should i aim at?. Looking at parts to replace once out before hand to save down timeLast edited by BL92; Today, 12:28 PM.

It calls for 1.8L not 1.7 iirc, fyi.
Yes remove the manifold - don't you need to get to the starter? At least the torx heads, though you go from below too ofc.DD: /// 2011.5 Jerez/bamboo E90 M3 · DCT · Slicktop · Instagram
