- Could you post the PN for the "Updated Banjo Bolt"? - Where is this bolt located in the 2.5T engine? - Can I remove the Banjo Bolt and modify it (i.e. gutting it of the internal parts), then re-install the Banjo Bolt? The Banjo Bolt in the Photo is the newer version that so far has no f...

Now I have the photos to show the issues I had. My wife's car was killed by the Banjo Bolt BB and parts. I swapped out the potentially engine killing Bolt from my car and made sure the Bolt was updated in the replacement engine for her car.

I found an engine with 90,000 miles and swapped it in, I also found the culprit responsible for killing my engine. The BB and the crosspin came out of the banjo bolt and beat a piston to death.

The top of the piston looked like it was hammered on with a teeny ballpeen hammer. It was a private sale I am not sure I have any recourse. I did think it made noises my o...

I have the same xc90 and the same thing happened, the top of the #2 piston looks the same as yours. It was a BB/check valve from the banjo bolt on the underside of the intake manifold. Seems like some years had this type of check valve and others just had a small hole. The top of my #2 piston cracked.

Well I installed and known good MAF and it is still missing. I pulled all the plugs again and the gap was bent over, I put in a fiber camera and the top of Piston #2 was cracked. Just for giggles I installed new plugs in all 5 cylinders and started it up. It seemed to run fine, I ran the car for abo...

My 2006 XC90 2.5T threw a P10108 Code yesterday and started to run really rough. I cleared the code and it then threw a bunch of cylinder misfiring codes Cylinders 2 through 5 and ran even rougher. Cylinder one was the only one not sending a misfire code. The P10108 code is "Manifold Air Pressu...
