Sorry for posting this super late been super busy with everything lately.
So i took the stem seals off the green circular objects.
I made a home made tool in order for me to install them and got a valve stem removal tool from amazon for $10.
This job i would give 9/10 10 being the hardest difficulty to do at home this is not an easy job like changing an oil.
Cylinder 5 was a nightmare to do it took me 6 hours to put the collet's on it since there is no room to work with.
Mean while i lost 1 collet and had to go to BMW Motorcycle dealer to buy that's right a motorcycle dealer had it and no other.
I also ordered the cam alignment tool, since the gears do have to come out obviously.
That is the one that i got.
I am going to align everything tomorrow and hopefully start the car tomorrow, i know that the Vanos is going to need a bleeding i have all the software DIS InstaD/P INPA etc.
Which one is the best to do the job and if possible any tutorials on how to run the bleeding would help.
I am going to upload pictures tomorrow of the tool that i made if anyone is interested as well as all the pictures that i took of the old stem seals and the new ones.
The job took me 2 full days to do just in case if anyone is wondering there is total of 40 stem seals 20 each side with each cylinder having 4.
