Boxster IMS update completed

New updated bearing and flange installed. Back together she goes!

996 IMS Upgrade
Starting tearing into the 996 project today to see what we were looking at. The first thing was to go after the intermediate shaft bearing which is the weak part of these motors.

Someone had upgraded the headers at some point (and mufflers) and replaced the …

The plan is to replace the standard maintenance items while it …

Intermediate Shaft Bearing
Ooops, I said it, the dreaded IMS issue of the boxsters and 996’s. This weekend we tackled upgrading the IMS bearing in a buddy’s 1999 996 C2. The IMS issue is the main cause of failures on the engines found in the early boxsters and 996’s. The early design was a dual row ball bearing, followed by the later design of a single row bearing. Typically failures are seen on lower mileage cars that are driven sporadically. The theory for …
