No Vanos units on M44 is there nah just the Dual chambered intakes.
Have you got a set of beisan seal for your vanos unit? I did mine in my M/S50tu made some differance. Doesn't eliminate the marbles but helps with actuation of system faster.
I also changed to Valvolene VR1 20-50 and my marbles left. Heavier weight helped as mine runs slightly warm it offsets the temps. |
