Let me introduce you to my car (some of you may know already because I bought it from the Bridgewater area), I drive a 2000 BMW 540it. It is a v8 station wagon and is painted glacier green over a black interior. When I bought the car everything worked great and I had about a week of normal driving then it stated running rough, turned out it was a bad coil pack on cylinder 8, $60 and 5 min of work later I was back running 100%. I drove the car off and on until about early May and that a when a cam position sensor went out on me so I decided to bite the bullet and whilst I is was working on the engine I decided to refresh the cooling system and may as well do the timing chain guides because PO didn't know the last time they were done. The job took about a month and the now I thought I had 120k of future trouble free miles because the engine held great compressino and had fantastic leakdown numbers when I got it back together. Well turns out I did not clean out the oil inside the cam bolt housings and all 4 cam bolts backed out when the car was running. After a couple of months of trouble shooting(all of which can be found if you want the thread I can PM it to you) I finally figured out it was the valves that must not be properly seating/sealing when it needs to be sealed. Turns out I was right and I had 13 bent intake and 2 bent exhaust valves, ok now I know why they say the "The most expensive BMW is a cheap BMW) but new heads were pretty cheap and now I have an engine that will be nearly new, so the m5 conversion I was planning on this summer may have to be pushed back so I can enjoy this car in its stock form for a bit. I will try and get some better photos of the car next time I am back home
