New Parts In an Old 01S

[thom4782]

Hi everyone:

My 01S reached 125K miles the other day so I thought it would be a good idea to invest some serious coin into maintenance. Some I planned; others I discovered during a close inspection.

Here's a list of the new parts that are now in the car:

1. Variocam chain rails
2. Variocam solenoids
3. IMS Solution
4. Rear main seal
5. Clutch (all parts except dual mass flywheel)
6. Chain tensioners (all of them)
7. CV boots (all)
8. Air oil separator
9. Oil fill tube
10. Motor mount
11. Starter

There are two items left on my punch list: replace the power steering high pressure line and an alignment. After that, hopefully, the big dollar items will be out of the way. Although, being a CA car, the next really expensive item might be the catalytic converters. We'll see if the car passes smog this summer.

I'd probably add a water pump to the list if you haven't changed it in a while...

Does it feel any different? I have heard that with the new variocam pads that resolve the cam deviations that things may feel "tighter" and you feel some more grunt, and also possible better gas mileage.

I had mine apart at 117,000 miles and I really wish that I had done the dual mass flywheel with my clutch replacement. I've kicked myself over and over for not just sucking it up and doing it. Someday I'll end-up pulling it apart to take care of that. Also look at the transmission mounts they are getting very old at this point and won't last forever.

Hi everyone:

Water pump was done <10K ago. Dual mass fly wheel was in great shape so I decided to take the risk. We'll see if that bet pays off. I'll add the transmission mounts to the punch list.

Too soon to tell if the MPG improved. The car is more drivable now but I haven't noticed a performance increase.


Thanks

I'm wondering about the feasibilty of doing an IMS at 125,000 miles. At what point, mileage-wise, would a rebuild of the engine be necessary? I mean, even assuming a healthy IMS what is the life expectancy of these engines?

Of course Raby would probably argue that this is the 2% and I would not argue against him as he has seen more failures than anyone else

Jeepdad,

I purchased my 99 Boxster with 104,000 miles in Sept 2009. I now have over 235,500 miles.

If properly maintained, I believe 300,000 miles is attainable.

I've got my heart set on a 996 once I reach 300,000 miles. As far as I know the IMS in my car is the one that came from the factory.

Enjoy!

Very nice. If you don't mind, what did this cost you? I'm already saying OUCH!

If you haven't done so already then I would look at the suspension next. I've replaced arms/bushes as a matter of course on both my Boxsters. Road conditions are perhaps a bit different here but they were changed at 12 years old and circa 65k miles on first car and on the current one at circa 105k and 10 years old.

I would second suspension, before an alignment, I would thoroughly look over your suspension components.
If any of your boots are torn or cracked those items probably should be replaced
I'm at 73k miles and now that I have parts in hand, I will be replacing Front:
Inner/outer tie rods
Lower control arms
Drop links and sway bar bushing
Then get a 4 wheel alignment
Roads here are pretty tough and I can feel issues under hard down hill braking

I have not done AOS or Water pump/Thermostat yet but they are also on my short list
