IMS & RMS failure rate on Tip ??
 

I read something interesting the other day in a magazine.... it was a review on the 996. The writer mentioned that the RMS leak issue seem to affect cars with manual transmission more than the tiptronic s transmission. (sorry forgot the publication, it was prob the 911& Porsche world, GT Porsche ??)

That got me thinking, how about the ims, does it affect the cars with manual transmission more than on tip s or it doesn't matter....

Any 986 tip owners with rms or ims failures out there ?? (I know I know, there are prob fewer tip cars out there than manual ones, we got more tip cars than manual here but the total 986 population is very small both in malaysia and singapore)

These failures seem less probable to tiptronics/automatics because there is SO fewer of them out there. People report them more on 5/6 speed manuals because that's what the majority of Boxsters are.

I wouldn't wait. I am doing the IMS/RMS on my tiptronic Ive only owned for a week.

Who knows...
 

though a very knowledgeable fellow says that because if the way TIPs are driven (slowly) and their probable oil change intervals (less frequent) there is some thought that the statistical probability of failure is actually higher than on a manual shift car especially if the manual shift car is driven with some spirit.

All you need to do it wait for the oil to warm and then take those revs up occasionally. I go to 5500+ at least once per trip. And change the oil at 3k. That should get your probability of failure back into the same range as the manual trans cars. And who knows exactly what that is ...

Not mine ! On the usual monthly journey home, mine's usually at 4k-6k rpm for at least 45 mins to an hour out of the 2.5 hour journey. Unfortunately, this baby has been under-utilized by the prev owner - 29k km in 9 yrs (red flag ??). I've put on15k km in just 6 months !

Yes, I always wait for the oil to warm up or at least anticipate (no gauge) when the oil will warm up before spirited driving.

But ah... oil change at 3k ? I was doing 5k and thought that was safe.. I've also started using 5w50 oil - that was the suggestion of the opc. Feels more slugglish but helps reduce the occassional smoking on startup, although everytime I wash the car, it's always a good bet she'll'll smoke the next day.

I've got a 2001, which supposedly is more unpredictable on whether it is a single or double row ims bearing.... if I do the ln bearing upgrade, it'll probably mean that I order both the single AND double row bearing or have the car held up for 3 weeks or so if I dont get it right the first time round ??? That's why I've been delaying the upgrade... (i know I know, it's still a smaller price to pay vs the possible failure).

We used to think that the tip cars saw fewer failures than manual, but thats not the case... They took longer to occur it seems but now we hear about as many IMS failure calls from tip owners as manuals, but fewer tips were made..

Experience has taught us that ALL years and models are subject to this, none really any more than any other.

Hey Jake, you say all years and models but I was wondering if you experienced these issues in boxsters that have been built in Germany vs Finland.

Mine was a special order made in Germany and I was curious if I have a better chance to avoid this?

I have a Tip car. Every trip down the driveway, whether it's across the state or around the block, I'll have the throttle pushed to the floor. The trans will shift at 6200rpm (peak hp) through the first couple of gears before I back off. It's addicting and I love it. I change the oil every six months regardless of mileage (less than 2K if that).

Drive it like the doctor ordered, that's my motto. :dance:

Ah well, bubble burst ! Time to save up for the insurance... I'm still reeling from the suspension upgrade/update and the brakes.

As the indie (and even opc) mechanics here aren't too experienced, I suspect they'll drop the engine to do the work.... I'm actually alittle afraid that they'll create problems that I didn't have before this...

What else should I change ? I've listed what I think...

1. AOS
2. Engine mount
3. Tip transmission mount

Anything else ?? I've already done the water pump, low temp thermostat and coolant expansion tank.

Ouch, the tip mounts cost $333 each and I need 2.... I think I'll wait and see the condition of those first.

Ah, forgot the rms. Does anyone have the part no for the rms ? Will it be the same for the tip and manual trans ?

I'm not surprised that IMS issues are same-same manual vs. tip, it's an internal motor issue. Also not surprising that the tip took longer to surface, these are typically run at significantly lower rpms than manuals, esp. when cruising.

It's true that the manual outnumbers the tip, but not by much and not until very recently.

Boxster production was virtually 50/50 manual vs. tip until '06. Production since has favored the manual and has tilted total Boxster production in favor of the manual, but only to about 52/48, that's what the local PCNA service rep told me.

There are loads of tips on the road folks. Maybe not so many on this forum, but they're out there.

Cheers!

I thought it was the opposite. Running at lower rpms leads to a greater load and less lubrication to the engine, leading to more likely IMS failure.

There are indeed a lot more tips than one would expect, as many of them are out there driven by lesser car enthusiasts. The IMS rate is honestly magnified in the online community. Keep that rpm high and the oil changes frequent. Heck, drive it in the snow too.

I'm surprised that the tips run at a significantly lower rpm than manuals esp at cruising ?? I find that the tip is practically a 4 speed gearbox... it starts off on 2nd most of the time, unless its cold or when I'm in a big hurry off the bat and the gearing seems to be quite low on 5th gear. On the bright side, it makes it more spirited and the engine is sweet spinning at any revs anyway. But the downside is the fuel economy isn't that great on the highway.

I think alot of the tips went to ROW (speculation only).... I would think that there is only one manual for every 10+ tips.... here in Malaysia and Singapore. (viewed alot of boxsters while looking for one and now I can't stop admiring other people's box when it's parked ! And after one year, I've only seen and heard of one manual in Malaysia and one in Singapore !)
