Boxster engine rebuild video

Sorry if this is a repeat post, but attached is a link to a video showing how a guy rebuilt his 986S motor. Even if you have no interest in rebuilding a motor, this video is a terrific tutorial on the motor structure, how it comes together and where everything is on the motor--highly recommended.

I did not know that the Boxster's (and I guess subsequently the 911s and Caymans) engines were 2 halves. I thought it was just one solid block....Wow, couldn't have been more wrong!

I just had my RMS and IMS replaced and I took pictures of it, and even then I didn't notice!

Here are some pics I took while the transmission/muffler/half shafts/RMS were out:

Glenn is actually a member of this board. http://986forum.com/forums/showthread.php?t=10042

I sent him some info last year about a crack near the valve stem, just like he had.

He is a very capable DIYer.

VERY informative to watch. This does bring up an interesting debate, however. Of all the things that seem to be issues with the M96 motors, the only one that can't be addressed here is cylinder bore wear/ ovaling/ cracked liners. As to the IMS, it looks like Glenn simply put it back together. I like the idea of using Autofarm's updated IMS solution if I had the whole block apart.

The 3.2 has the thickest cylinder liners of all the M96 blocks, with the 3.4 and 3.6 being the thinnest. Either way, it seems they all get oval with time, and some unfortunately, develop cracks in the liners themselves. I love the idea of freshening an older block with new components/ upgrades, but this seems to be the one thing that cannot be fixed, short of re-sleeving the block like Autofarm does.

More than likely Glenn's motor will last a long time and be very happy, but now that these cars have been on the road long enough, and there are plenty nearing higher mileage, it seems fitting that someone would come along and offer a complete, thorough rebuild program which would give an option to buying a new motor from Porsche (or simply buying a used motor with all its unknowns).

Just food for thought. Great work Glenn!
