I've been searching for information on performing this service. The Haynes manual apparently considers this such an easy task that it doesn't need to explain it. I've found write-ups for the 850/early 70 series which is very similar, and I understand the basics of the job. Are there any things I should be aware of while doing this job that are specific to the P2 V70? Any advice is greatly appreciated.

 

It's quite different than an 850 and also different between a turbo and a non turbo.
The general principal is the same but that's about it plus the parts cost about 50% more!
