Whats a good Service Manual for Porsches?

[Johnny-5]

Im looking for a book to help me with torque specs, break down, IMS bearing, things like that. I know theirs a 101 Project book but is that good enough? Or is the Bentley Manuals better? Just curious. Im looking for one specific to the 996 CAB and 986. Thanks in advance

Problem is that Porsche stopped publishing service information around 2005, switching to an online subscription system; and has never conceded that the IMS bearing on engines up until 2005 could change the bearing without splitting the cases.  By far, the best compilation of torque specs is found in the two book set titled "Fastening Specifications" that Jake Raby published, as he has provided data the Porsche never published.  LN Engineering published the best set of instructions for IMS retrofits.  There are some internet sources for PDF's of Porsche's service data, but be careful and some are woefully out of date.

Thank you for the posts. Ill get the Bentley for more general info and will look into the Jake Raby book. I believe you are right about LN Engineering but i believe I can find the info online through DIY and other searches so Ill focus on both the Bentley and Jake books first. Thank you again and hopefully I can get this boxster up and running soon! 🙂

I would suggest caution depending upon online "DIY" articles; many of them have been the sources of vehicles that showed up at the shop on flatbeds after that DIY went very, very wrong.

 

You would be infinitely better off depending upon sources like LN Engineering and Jake Raby.

With regard to service manuals, Im brand new to 911 ownership so I've been doing research on them here too. Im not new to vehicle maintenance, much of it aviation. I agree many manuals can and have been superseded but that doesn't necessarily mean they have no value. In my mind, they are part of a necessary picture of the systems in a vehicle. If studied they can greatly increase one's knowledge of said system. Comparing the guidance available on the internet with what is in these manuals should allow one to do quite a bit of DIY maintenance with relatively low risk. That has worked for me for years on the other machines, I see no reason a similar approach to these wont work here. That's my plan. That said, I got a complete set of manuals recently in digital format from a fellow Renntech person that is a library of very valuable information, much of it from the factory with which to compare and educate. I'm still going through it. The specs info you mentioned is there too. I highly recommend anyone needing them as part of their own resource library to contact Keith Hartley here. He goes by "Porschelibrarian".
