Randall, why is it tricky?

Have you had much experience in other engine configuration(V, straight, ect...) such as engine rebuild or just overhaul? not trying to poke at you or anything... just curious about your reply.

Seriously, resetting the placement of the cam chains can be very tricky as well as a couple of other issues (all of which produce a kaboom! if the motor is fired up). I'd never pull mine with the intention of tearing it down without a lot of training from Flat Six Innovations or a qualified training center.

Trey, it's only tricky to me because I've read a bunch of stuff from Flat Six Innovations about how a guy in CA with no Porsche motor rebuilding experience totally screwed up a motor in a customer's car because he approached the rebuild as if it were a domestic motor (chevy, ford, etc.)

Evidently, there are some special things going on inside a Porsche motor.

Look for a forum member named "Jake Raby" and PM him and ask him and I'm sure he'll be happy to tell you about it. BTW, he offers classes north of Atlanta on how to tear down and rebuild a Porsche motor the right way.

If I were rich I'd take that class in a heartbeat. I would love to learn how to do that.

It is “tricky” because a number of design issues unique to the marquee, such as a split alloy case block which is difficult to nearly impossible to repair if you spin a main bearing, because of the significant number of special tools and fixtures needed for the M96, because of the dearth of technical information about the assembly, and extremely limited number of aftermarket internal part suppliers. These are the same reasons why the dealerships do not allow their techs to get too deep into these engines………..they are not for the faint of heart, pocketbook or time…………..

please HELP!! I was going to through the book and everything was fine and dandy.
I got to the part where I unbolt the tranny from the engine ( 7 screws)

the Bentley Manual told me to unbolt them in an order from the top left bolt all the way around unbolting clockwise until I got to the top right bolt.
I unbolted the first three until I got to the 4th bolt. I spent some time trying to find it and I saw one but didnt think it was that one, BUT that's the only bolt there and this bolt is not like the others. Can anyone tell me what tool that is?????? to take off this bolt. All the others are the same except that one. Damn those Germans!!!
please help I would've taken picks but my camera was dead. I thought it was an ellen tool, But it's not it has more edges, even more than a star. Please help

I know the one yourtalking about. You can't get anything on it right. I grinder mine off and now use a regular bolt. That is not the right way but that is how I got it done. Sorry if it's not the answer you were looking for but it will work.

dti · 05-15-2010, 10:52 PM

So theres no regular tool for this? like a star shaped ellen tool or a socket?
something that I can get at like a regular auto store? I really wanted to take this off tomorrow.

Ah, I HATED that bolt. I looked forever trying to find it (12 point torx). I ended up grinding it off with my dremel cut-off wheel. Not easy, but it works. I then just bought a regular bolt to replace it and no more problems.

Just for reference, the heads can be replaced without removing or even lowering the engine on a Boxster. I had my heads off before I removed the engine.
