Timing chain & tensioner '92 525i

Actually you're right. Looking at the picture again, there are two arrows on the exhaust cam sprocket. I wasn't paying attention. Again the arrow and Bentley's vague description "first cam lobes pointing at 2 o'clock and 10 o'clock" blah, blah, blah...come into play.

Yes there are two arrows on all 3 sprockets . If you look closely there are two arrows in the Bentley's pics too:-) They have also tilted their engine so the arrows are vertical when we all know the engine is cranked to the left:-) Anyway, the camshaft timing marks I meant are on the flats at the other end of the camshaft - two large dots plus two letters which I take it mean inlet and exhaust. Pretty simple stuff. Will sort out my link and post some proper pics!

PS Just noticed from your pic that slots in the sprockets are not alligned to the left :-)

Not on the VANOS engine intake sprocket because the timing is variable. Do you mean the mark on the end like this?

Oops. Mine is not vanos. But yes the two dots are the marks I meant. Provided you have the two flats in a straight line then you should be fine. In the pic yours seem a bit out but I'm sure you didnt leave them like that :-)
