been slow working on her due to time cosuming work project. but have managed to do the following so far
removed the belt to make sure it was not one of the pulleys-- noise was still there at 3000rpm
drained the oil--found nothing
cut the oil filter apart -- found a few really small pieces of brown plastic ( about 1/16" in diameter)
dropped the oil pan to see if larger pieces in bottom-- found nothing
put it back together put car on trailer and took it to a porsche mechanic friend of mine to hear the noise. he sais it is ims bearing or a bad tensioner.
about 2000 miles ago i replaced the ims bearing with a LN Engineering bearing and do not think it could have gone bad. so i will purchase the tensioners and swap them as soon as i can get a break in my schedule. will keep you posted
