This has always been a great resource for OB maintenance.


To quote directly from (Saint) Doug_B_928....

"This is a procedural write-up I created following my first DIY timing belt change. There wasn’t a newbie rated procedural guide with pics for a 16V so I thought I’d put this together so I could use it when I do the job again and in case others would find it helpful. I am not a mechanic nor am I a 928 expert. One takes this job on at their own risk, but Roger Tyson (928sRus), Wally Plumely (928 Specialists), Jim Morehouse, and Dwayne encouraged me to do the job myself and I’m very thankful as I found it to be a lot of fun. I used Dwayne’s (Dwayne’s Garage: http://dwaynesgarage.norcal928.org/) pictorial write-up for his 32V 87 as my base, added in information from various other sources on the web (Pirtle, Bill Ball, Sharkskin, the FWSM, etc.), and then figured out the differences between my 16V and Dwayne’s 32V as I completed the procedure. Huge thanks to Dwayne for his efforts in his write-up. I would not have undertaken the job without it. This write-up is essentially a 16V supplement to his, with additional information that I picked-up along the way. I have organized it exactly the same as Dwayne’s and tried to keep everything (the text and pictures) as similar as possible so that interested readers can compare the differences between doing the jobs on the two different motors. The 16V job is simpler in several ways, and I’m hoping that other newbies will find this helpful because they won’t have to go through the trouble of figuring out the differences between the 16V and 32V along the way. Having said that, Porsche was always making changes, and previous owners/mechanics may have made modifications, and so others’ experiences with 16Vs may vary."

That is a great guide. There is an updated one from Nov. 2012. I do not know if that is the latest or what revisions/additions were made but here it is.

I andolutely LOVE this... When another set of eyes looks at a procedure they are completely unfamiliar with they often point out "obvious" short falls that the experienced wrench often overlooks. Great job!!

Thank you Daniel! This is the type of posting that will make Open-Road more popular with newer 928 owners and thus into a more frequented site.
Anyway to make it a sorta "sticky item" since it is so important to an OB ownership?
