another dead boxster @#$%!

Great thread and even greater explanations of potential IMS issues and how it is addressed by Jake. Given the amount of IMS related inquiries by new / concerned forum members maybe this ought to be stickied along with links to Charles Navarro's Youtube explanation:

Great job Jake.....

Unless I missed it, could you post a picture of his failing IMS bearing?

He hasn't gotten to that point yet. There was bearing seal materal in the oil pan but big problem was a failed AOS.

We'll extract the bearing in the coming week now that Pat has agreed to march forward with that process.

You guys will be disappointed with the lack of bearing damage thats visual, more than likely when the bearing is extracted. This is because the tiny bits of seal that we caught in the oil sump are the very earliest stages of seal failure, which is best case scenario for catching an IMS when going south. The damage to the bearing is nil at the present time, BUT the damage will progress fairly quickly once the seal is fully compromised and the permanant lubrication is washed away by the engine oil.

This is best case scenario for Pat, because if the bearing goes further and starts to fail it is more difficult to extract and damage to the IMS tube is possible. This is why being proactive is REQUIRED.

Pat is at great risk for an IMS issue because:
1- The car is an 02 model with a 2.7 and a single row bearing
2- Its a tip
3- Because its a tip coupled to the fact that the car has been driven very easy by Pat because he didn't want to experience an issue..

When driving this car it shifts into 5th gear when in "drive" mode at less than 45 MPH at an RPM of less than 1800.. That spells disaster for the IMS bearing which sees MORE load at the bearing than at higher RPM.

Its a good thing that Pat had the AOS failure and thought the engine was scattered, else it would not have had the sump plate pulled and the seal material would not have been noted. This would have led to bearing failure out of the blue.

This is the procedure that we'll be carrying out for Pat on Monday, Tuesday and Wednesday of the coming week in detail. I still have to add pics of the process to the site, but I am so busy helping guys like Pat that I just can't get that done!

We are in work this morning doing the final compression and leak down tests to ensure that the issues with Pat's Boxster have worked themselves out. I'll post results in a few minutes as soon as we complete the evaluations.

I have the IMSR procedure scheduled on my schedule for tomorrow and Wednesday, we'll be posting the entire procedure here from start to finish.

[Jake Raby]

Here are the compression numbers from this morning's tests..

The numbers are good, we did the test warm since I drove the car in this morning. The good news is that #1 has dropped back to the normal numbers.

Here they are-
1-195 PSI/ 4% leak
2-190 PSI/ 4% leak
3-190 PSI/ 5% leak
4-190 PSI/ 6% leak
5-195 PSI/ 6% leak
6-190 PSI/ 6% leak

These are good numbers from a warm engine with 86K miles. We are marching on with the IMSR procedure now.

Pat's IMS has been retrofitted and the seal was definitely compromised!! I'll show you guys how we knew this tomorrow when I post pics.

We'll have the car back together and on the dyno tomorrow!
