yeah it was the tool to rotate the cam sprocket I was thinking of. They don't cost very much but the proper tool for clamping the cams themselves costs well over a hundred.
My 325 is an auto too which also kills some of the low end and torque across the range generally. Once I've recovered from the £470 worth of parts I've thrown at it in May
I was planning on doing a transmission fluid drop and refill, new filter etc in the next month or so. That should help a bit.
My DISA is fine, it was one of the first things I check when I bought the car to make sure that the pin wasn't about to drop out and take out a valve. You hear a definite change in engine note at around 4K rpm that I've always assumed was the DISA cutting in but may be wrong, that may actually be the VANOS cutting in?
