I wonder who has the highest milage Boxster with the original IMS???

A friend has a 1999 986 with 75,000 miles on the clock. Original IMS.

Disclaimer - forgive me if this is a repeat thread.

 

My 98 just turned 151,000.
Purchased it in '17, with 114,500 on the clock. I embraced the, "If it has run that many miles, the odds of failure are reduced".

So I'm just playing the odds.

 

I just pulled a Boxster engine out of a donor car, locked up ..288K on the clock..The IMS is failed.I cannot say if it's the original, but it sure looks like this was NEVER apart, clutch is pretty bad too

 

Have you actually seen the failed IMSB? How bad was it?

The engine in my green base Boxster has about 106000 miles on it, the IMSB seal was removed during inspection about 8000 miles ago.

 

I just bought a 2001 Boxster S with 117k miles and the original bearing. It was still good but the seals had failed and from what I have read this is the first sign of failure. When I pulled it out the IMS was full of very black and smelly oil that got trapped behind it.

 

I had the IMS done on my daughter's '01 with 145k. The seals were intact, but the grease was washed out and the bearing was starting to get wobbly.

 

​​​​​​​... That is impressive.

 

Got an $800 1999 Boxster with 244k miles and a hole in the engine….. IMS was perfect, but a tensioner went and made a mess……

Put in a used engine (with 80k on it) did the IMS and three tensioners, and the car is back on the road…..

(and a water pump, and shocks, and suspension arms, and a starter, and an alternator)

I have a 2000 2.7 car with nearly 150K on the clock. It is on a factory replacement engine, which was replaced at 17K miles. That said, it is still on the original clutch and the IMS has not been swapped out of the replacement engine which now has 133K ish miles on it.

 

My 2003 2.7 needed a clutch at 75,000 miles, So I did the IMS at that time. The mechanic said my bearing was good.

 

‘98 w/ 155k mi, original IMS

 

I bought my 99 Boxster with 107,000 miles on it with the original IMS but due to fear of failure I replaced it along with a lot of other neglected maintenance items. I now have 117,000 miles on it - 10,000 miles in 4 years - I drive it more now that I've moved to Tucson, AZ.

 

my dad has a 1998 Boxster 986 with 119,500 if i remember correctly it has headers and cat deletes and eibach sway bar original motor recently had a misfire issue but it is solved cause bad o2 she sounds good and is running amazing and is much happier she feels like we have all 201 hp i absolutely love that car can't wait for my dad to hand over the keys to me some day the mauale shifter and the sound of that flat 6 in high rpms is so addicting ugh sorry for the side track got adhd

 

99 Base with 180,000+. Original IMSB and clutch.

 

As far as I can tell, my 2000 Boxster S (3.2L) is on its original IMS bearing with 147k miles currently on the clock. I cannot say that with absolute confidence, but I do have a lot of receipts that accompanied the car including a new transmission, but no record of an IMS bearing replacement. Even the Carfax, which does have a lot of detail in the repairs, does not list IMS bearing as one of the items. So, to my knowledge it is an original bearing.

My attitude about this car has always been that it owes me absolutely nothing, but I will be having the engine swapped to a different engine in the future...so if this one does goes it goes out in a blaze of well-deserved glory!
