so did the vanos seals today as i seemed to have a slight clatter as they do from the vanos.
The car doesnt seem to have gained much in terms of power (wasnt expecting bhp gains obviously) but some people describe the difference night and day. Can say that the clatter has been solved and the revs dont bog much with the ac. Although it may be too soon to say yet
The old seals were flattened pretty much and they was some movement when removing the vanos pistons.
Took exactly four hours which was near enough the book time and i took it real easy- could be done again in 2.5-3 hours tops. I also did the VCG so majority of the time was cleaning the old bits and bobs
Would recommend doing the seals as the old ones seemed tired and worn and hard- although not as bad as some other that ive seen which is good to know
