Blown Engine

I have owned my car, I have been only changing my oil at 12-15k mile intervals (using only Mobil 1 0W-40 motor oil), and at 61k miles now on my car, my engine still has not imploded (no D-chunk failure, no slipped sleeve issue, no IMS bolt failure, etc). I do not have an upgraded LN IMS bolt. I do not have the low temp thermostat installed. I do not have that magnetic oil drain plug, and all the other goodies. My engine is still running. Ain't that amazing?! Listen, there may be a hundred different ways an engine can fail, but that does not mean that your engine will not last well over 100k miles without doing any of these upgrades. The percentage that do fail...even if at a high rate of let's say 10%, means that the other 90% will never see any issues whatsover!

I'm not saying that you shouldn't do any of those so called upgrades if you are worried, but it is a shame you are being scared into possibly selling the car, and not enjoying what a wonderful car the Boxster can be because of what you are reading on the internet. Again, take a deep breath, and relax. You car will most likely not implode on you, as the failure rate is still a minority percentage relative to all the cars produced.

i HAVE THE BEARING WHICH i'M SUPPOSED TO CHANGE THIS WEEKEND BUT i WANTED TO KNOW OTHER UPGRADES THAT i COULD DO TO BE SAFE DUE TO THE FACT THAT MY TRANSMISSION AND OTHER THINGS ARE GOING TO BE APART
THANKS IN ADVANCE

I'm gad to hear you're keeping the car, and if the IMS bearing upgrade lets you relax and enjoy it, it's well worth it.

I believe the other failure modes require more engine disassembly, off the top of my head : timing chain tensioners, lifters (not catastrophic), C-chuck failures ( rare except for '99 or so ) , oil pump drive ( very rare, only racing? ), rod bolts ( very rare-racing? ), oil starvation under racing conditions ( only with racing tires? ), cracked heads ( rare ) , heat exchanger leaking water into oil ( rare ), water pump failure-broken shaft.

I believe you have a Tip, so no clutch issues?
