another dead boxster @#$%!

[Jake Raby]

After seeing that the IMS probably is not the primary reason for this episode as the bearing seal is just now being compromised the diagnostic process continues in another direction..

At this point it could be something as minor as a blown Air Oil Separator (AOS)..

Then I noted an exhaust flange that was wet with oil on the 1-3 cylinder bank and that was suspicious.. See the pics.

The next step in diagnosis is finding out why that one exhaust flange is wet, if the issue is the AOS BOTH of the exhaust flanges would generally be wet with oil, so now I am thinking the engine had a failure on the 1-3 cylinder bank.

We have pulled the spark plugs and are in preparation for a borescope inspection, followed by a leakdown and compression test. When the #1 spark plug was pulled that cylinder was full of oil, so looks like we have found the smoking gun...

This engine hasn't been written off yet, it could still be nothing more than an AOS, but now I am thinking cylinder/piston failure or a valve failure that busted the piston.. The diagnostics will tell us.

Pat did the right thing, he shut the car down at the hint of a problem and did not try to re-start it, neither did we... We assume the worst from the beginning and then work our way out to the simpler things.. Lots of people approach this in an opposite manner, only to waste lots of time and the customer's money.
