read this and be warned about your motor

[jhandy]

I dont want anyone to think I am trying to scare the boxster community. My whole point of this post is to let people know what may be happening in their cars.

I am the normal boxster owner...I dont track, it is my daily driver, I love to rev it up on the twisties and a long strait road screams for a 0-100 test drive.

I change the oil and care for the care like a baby. Aside from a little hesitation on cold start up, I thought it drove fine. Unknown to me I had all of these things wrong with the car.

Tappets are one thing, but read here about chain tentioners...http://www.lnengineering.com/chaintensioner.html
and we all know about the IMS.
I was all confident about letting it blow its self up and replaceing the whole motor until I heard about the aftermarket companies not replacing the motors due to fine print reasons. Then I read my contract. Pretty scarry if read with a critical eye.
That is why I sent it there to be fixed before it became a paper weight.

As far as costs go, I am hopeful that the warrenty company will pick up the bill, so I am out 200$. So for those without warrenty, I suggest you call Mr. Raby and inquire about prices.

If these lifters are such an issue and are going at such a low mileage how are there a handful of people with near 200k on their boxster on ppbb? One dude on there even has 225k on the original engine!

(not starting an argument just wondering)

I wonder the same thing though I'm starting to think the really high mileage M96 motors with no issues are more of the exception than the rule? I think there's enough enough evidence out there that the M96 motors are more prone to some of these issues that we would all say is ideal. There has to be a percentage of them out there that don't have any issues though wouldn't there?

I have a friend that blew up his Lexus IS350 motor earlier this summer with only 25,000 miles on it. Lexus was so shocked they shipped the motor off to Japan for autopsy......it certainly seemed to be the exception for one of their motors which normally will run 200/300k+ miles without issue if well taken care of. It does happen though.

Sadly it seems like the M96 cars are on the wrong side of the exceptions right now.

I have had zero success with using the old fashioned Marvel mystery oil/ Kerosene/ tricks that work with other engines when applied to the M96.

The lifters have very small internal passages and when they become clogged the solvent/etc will not attack the gunk well enough to remove it.. If it does it'll more than likely just go to another place within the same lifter, or the next one down stream..

I have had success pulling lifters, taking them apart and cleaning them, BUT that takes a lot of time.. You end up paying as much in labor as the cost of new lifters.

if anyone reads this that plans on doing the lifter swaps themselves, you might want to think twice about buying the Porsche lifters... The Febi replacement units are much nicer.

We ended up buying new lifters and having new internals made for them, these don't clog nearly as bad(if ever) due to their design and clearances.. And we can apply this technology to used lifters and resurface them if money is a concern. (as long as the lifter isn't damaged.)

The same goes for timing chains... Porsche designed them "linkless" so they can't be changed without full tear down.. We put a stop to that!

Do you think the warranty company will deny your claim because you are "upgrading" the engine with Raby components and not Porsche replacements? And technically nothing failed, it was more like preventative maintence? Keep us posted.
