Here is an update to my IMS replacement saga.
I finally got everything done and started driving the car a week ago. Last weekend I put 100 miles on it and decided to change the filter and see what was going on in the engine. I did expect to find metal in the filter as there was so much in the IMS tube when I removed the old bearing. (BTW, the old bearing was intact but wobbly and had been shedding metal into the engine).
Here is a pic of the rag I was using to swab out the IMS tube.
As expected, there was a lot of metal in the filter when I cut it open. I am glad I chose to go to a non-bypass filter and magnet setup. All of this may have been captured in the first few minutes of running the engine after putting it back together.
I put on a new filter last Sunday, topped off the oil and drove it another 400 miles this week. This morning I cut open the second filter. I have been sweating this moment all week, but I am pleased with what I found.
No visible metal in the filter or oil!!!!!
The filter mag did trap a little more metal flour, but that is really all could find. There were a few tiny black bits of non-ferous material, probably from the chain tensioners.
I know my engine has been compromised by the failed IMS bearing and this will undoubtedly shorten its life. But, at this point, it is running very well and sounds great. Hopefully I can get another 20K or 40K miles out of it, fingers crossed.
Also, here is a pic of the filter opener I bought. Nice tool! Opens them like butter!
I will be driving the boxster to work most of next week as I intend it to become my alternate daily driver.
