Wanted to share my experience with recent S54 Vanos rebuild. I do believe the process is easy if you have the right parts, instructions, support and take your time.
I initially ordered the ECS kit and found what they sent to be very confusing- dozens of bags with individual O rings, some of them numbered incorrectly compared to instructions, seemed to match the old parts in size but I did not know for sure. One O ring was even stuck to the outside of a bag. Long story short, the intake piston didnt function properly when I reassembled. I tried to re-time it several times but intake piston did not move.
I eventually rebuilt everything with the Beisan parts and runs perfect now. I also purchased the Beisan exhaust hub, solenoid and oil pump disc, which are very well made. The bags they send with matched rings nested make it very clear how they need to be installed.
Raj at Beisan is very helpful at all hours and highly recommend working with them for any Vanos parts.
I will say I have worked with ECS for many years and they are great at getting any OEM part you need quickly at a great price. I sourced almost everything from them for my SMG to 6 speed swap last summer. They were also very helpful when I called them today and are refunding the cost of their rebuild kit. Point is for this specialized project just use the experts at Beisan.
