Hello, nice work getting that OBD2 that is very smart of you. I don't mean to be annoying but IMSB and the cam shaft deviation are two different issues. The IMS is in the center bottom of the engine and is connected directly the exhaust cams via chains. They are mechaniclly locked. From the exhaust camshaft there is a chain connecting to the intake camshaft. Between the camshafts is the variocam Solenoid which has two small plastics pads that the chain rests on and are used to change the timing of the intake. The solenoid moves the pads in and out to change the position of the intake. The issues is that these pads wear out faster than expected and are considered a maintenance item. These pads only cost about $55 per set per side and Porsche release a new version made of harder plastic. The problem is that these are very rarely changed and if they fail can result in total loss of timing and brick the engine. The reason they are not changed is that the labor to do this at a dealer is cost prohibitive. You have rent a special engine locking kit, lock the engine in TDC, remove all three chain tensions, lock the cams in place, remove the oil scavenger pumps, remove the valve covers, etc.. It is a ton of work to just replace these pads.
Thank you for this. I was checking to see if the deviation changed while connected to the Durametric. The 6 degrees camshaft deviation I believe is an indicator of pad/tensioner health. I may be tackling inspecting and replacing these pads over the winter. Stay tuned!
Glad to help, I did this to my Boxster just a few months ago, they were about to fail. Do you think you will be doing this yourself? @@AttainableLuxury-vv2xq
FYI, I love that color and that you are getting into the details about ownership. I have both a newer 911 and a 2001 Boxster S. But with older cars and especially the ones with the M96 engine there is a lot of things you need to know before buying or you can really get thrown for a loop.
Anytime, This generation Boxster 986 are a really great car and can bought at reasonable prices over similar year 911s. But buyers need to be informed about issues like the IMSB and these pads, and for Boxsters 2004 and above the "bore score" issues. Luckly it seems to be that the generation 1 cars no suffer from that issue. @@AttainableLuxury-vv2xq
Thank you for watching and commenting! So often I hear it pronounced without the “e” but I try to make sure to pronounce it correctly. Maybe it will catch on 😄
If hubby is an engineer, and he has time, then pre emptive maintenance best practice, would be too change ims and pads, not a 5 minute job, but diy would make it more affordable. Your car is very nice.
WOW, Where can I get that Durametric testing done? Do most shops have that? Does that also work with 1999 Boxsters? And are any relatively cheap devices available and one could test this AT HOME? Thank you, great video!
Thank you! Most shops have their own Durametric tools. It’s relatively affordable and I believe I put a link for the one I used in the video down in the description. Good luck!

Great video, thank you. I monitor the oil filter at each oil change (5,000 miles) in my Boxster 99.
Great tip! Thank you for watching and commenting. It's helpful to hear the experience of others. Enjoy your Boxster 99!
Thank you, makes me realize i need to spend more time with my durametric, another great show, so jealous of that color and hard top
Glad you enjoyed it! Thank you for your comment!
Very informative with the durametric! Great video!
Glad it was helpful! Thanks for watching!
Superb Porsche channel. Thanks
Thanks so much! Glad you like it!
Have a 2003 Boxster S, over 250k kilometers and runnng like a swiss clock.
Subscribed. Very good video

Thank you so much! Enjoy that 2003 Boxster S 😎

Yes, I agree! Hopefully, what I'm sharing will be helpful to someone considering one of these cars. Thanks for watching and commenting!

Very informative.
Thank you! Appreciate the comment!
Impressed😊
Thank you!
Great to hear you pronounce Porsche with the hearable „e“ at the end, as it in German meant to be.

I totally agree! That’s on the list of things to do. I’ll try to film it if possible.
did anyone mention getting the oil tested at a lab?
I’ve heard about that, but never done it myself. What do you think, worth it?
Great videos. I love your hard too. Nice to see a woman join the Porsche / car social media scene.
Thank you! 👍
