As tires age, they harden with the recurring heat cycles, even from street use. Had a situation a few years back when my track tires felt like they had heat cycled out but still had plenty of tread. Decided to replace them with my street tires to finish out a season; bad move. Despite having at more than half tread left, they had less grip than the dedicated track set, even though they were usedby MikenOH - Main Forum
Sorry to here about the scratch and run. It never ends--one reason why my Boxster will never be a DD. While a 993 is doable, I suspect we are in for a very bumpy stretch as far as world peace goes; too many countries around the world with governments in play and old grudges to settle. We live as they say in "interesting times".by MikenOH - Main Forum
Guenther: I've got an 06 with 39K on it and am getting close to the same maintenance items you are. During the spring visit to my Indy, I'll do the T-stat, thinking about the water pump and probably a UDP. Had the serpentine belt done this past spring along with spark plugs and coils. Also, thinking about dropping the bumper and do a thorough cleaning of the radiators because we do track events.by MikenOH - Main Forum

QuoteGuenter in Ontario A few things to consider before buying this car. - since it looks like the body hasn't been looked after particularly well, I'd be VERY concerned that it wasn looked after mechanically. As Grant pointed out, that could end up being expensive. - living in South Florida, you don't know how lucky you are when it comes to knowledgeable Porsche mechanics, you've got Pedro, onby MikenOH - Main Forum
Quotegrant I actually like the mopar blue. and its free. Just a word of caution. You are going from a well behaved car (boxster) to a car that does not tolerate certain errors (SC). I have several friends that lifted at the wrong moment (like the downhill at LRP) and wound up in various walls. Treat it with respect!

Jeff I know he's done one IMS replacement and is currently rebuilding a '99' --IIRC--to be a track car. Nice guy, knowledgeable and very connected with the Mid-OH region club, if you need references. His shop is off 71 near the Rt 61 exchange, a bit north of Columbus.by MikenOH - Main Forum
Pedro: Somewhat related--did you ever do a water pump on your old engine? I've heard comments from others about preemptively replacing it in the 40-60K range--especially if you track your car, because this is a weak point.Thoughts..?by MikenOH - Main Forum

Just for grins, I ran the idea of what was involved/recommended in splitting the case to replace the IMS on a 987 by a couple of Porsche mechanics and the consensus was while you're in there , do the typical wear items. Depending on which pieces parts were chosen to be replaced, this gets to be a very expensive proposition since there are a lot of wear items which would be a problem and need toby MikenOH - Main Forum
Now that they are in stock 18" 987 sizes, I'll replace the NT05's with these. On your sizes, I think they are under $500 and you can actually drive them on the street without wearing hearing protection.by MikenOH - Main Forum
A thought on that: --The 987 requires the engine to be pulled and the case split to replace the IMS, unlike the 986 in which the IMS can be replaced with the engine in place. This makes the proposition on doing the IMS considerably more expensive labor wise; while you're in there I'd expect the chain tensioners, that oil pump piece and possibly the lifters would also be replaced, raising the eqby MikenOH - Main Forum
makes perfect sense in an aircraft, given the downside of what happens when an engine fails while not on the ground. Since the technology is being used in aircraft successfully, we should also expect it to work in an application in an application like the IMSG, assuming proper testing has been done.

Mike: I'm sure it would be difficult to estimate what the time/mileage line is between where the first wear starts on the IMS until it gets to the critical point of near failure, given differences between oil change intervals, driving styles and the OEM components/installation on the individual car. Jake is in a position to make a guess on this given his access to engines and IMS set-ups and woulby MikenOH - Main Forum
Any idea how many hours or miles from the time that the seal may start to breakdown to the time that the bearing/stud might get critical? I'm guessing Jake has an idea. If you had an idea of what that interval was, you could drop your oil filter every --you pick the mileage--and even drop the magnetic oil plug (have a clean one ready to put back in) and evaluate both for metal shavings.

Thanks, Trygve, for your experiences with it. Just looking over the video on his iPhone looked impressive but I've seen other video --mounting on the windshield--with the wobble, to the point of making one nauseous. How did the data overlay get added to the video which was from a separate source?by MikenOH - Main Forum
I saw this at the track today and it looked very slick, besides being inexpensive--$19.00. Very good video via the iphone; App records lap times, speeds (via gps) and shows G forces--supposedly has a OBD input capability. The obvious question is accuracy in lap timing and in speed. I don't have an iPhone but this got me thinking about one. Thanks for any feedback in advance.by MikenOH - Main Forum
Went through this on a RAV4 with OE tires that had plenty of tread and no unusual wear patterns. The tires were amazingly loud to the point where conversations were difficult, so with only 7K on them I had them rebalanced--wha-la--greatly reduced noise. Since your tires sound like they are due for replacement, re balancing would seem to be unnecessary, but would keep this in mind as the miles mby MikenOH - Main Forum

I had been using M1 15W-50- mainly for track days- and this was first year I left it in over the winter layup. The car started right up and was quiet initially but after a 15 minute drive I could hear the ticking which eventually subsided as the car was driven daily. Oddly enough, I've had the same type of ticking--intermittently--prior to that, using M1 0W-40. As I mentioned earlier, the mechaniby MikenOH - Main Forum
Did you notice any engine "tapping" noise after start up or driving after a while? This spring I had the tapping noise when I first brought the car out but didn't really notice it until I brought the car back to the garage to be parked. At the time it had M1 15W-50 in it and had been sitting for 5 months. I've got a short video of the noise which I can post if you heard anything.by MikenOH - Main Forum
Agreed; from the various posters on this board and fellow boxster owners that I know, cars that are daily (or nearly) driven seem to have the best chance of being able to go 100K+ without major mechanical problems. I've experienced the same lifter problem--usually at spring start up when I was using M1; I've changed out to a different oil (Lubro Moly 5W-40) and it will be interesting to see if iby MikenOH - Main Forum

QuoteTino The PDK transmission also seems sluggish on take-off, but again, that might just be me not getting on it as you should. One surprising trait of the PDK is that it allows the engine to run at much lower RPM's that I am used to.
