Also, you do not need to take that bolt off to separate the case halves, even then only if you're doing crank work or replacing the main bearings.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Cross-post from Boxster forum, but casting my net wider, as it pertains to an M96 engine. ----------------- My first engine tear-down. Got an M96 2.7L cheap from a buddy and am tearing it apart as practice for a rebuild on my 140k plus 2.5 on the '99 Boxster. Got the heads off and am ready to take the two case halves apart. Ran into this serrated bolt. What is it and what do I need to loosen it? Photo attached shows the bolt just above the chain, in the upper quarter of the pic. https://rennlist.com/forums/members/...rated-bolt.jpg

One of many Porsche special tools needed, available thru Hazet, Baum, maybe even Snap On has an equal, if memory serves correctly. It's one of many special tools that you should have in your tool box if you are going to seriously be rebuilding these motors. I can look up the actual tool number and supply it if you can't locate it.

POST 3 / ORIGINAL POSTEROriginal post

Thanks Viking. Got most of the special stuff, but this one was a surprise. Any specifics are welcome. Joost

XZN sockets or 12 point sockets. Amazon Amazon

POST 5Original post

A regular 12 point socket will be fine. Also, you do not need to take that bolt off to separate the case halves, even then only if you're doing crank work or replacing the main bearings.
