I just changed both timing chains, guides and tensioner on my '92 525i non vanos engine. Due to my work I have a limited amount of time to spend so this has taken a while. While I appreciate you need to have a warm engine to get an accurate reading I am getting zero on all 6 cylinders. I dont even the 'chuff chuff' sound. Not surprisingly, the engine wont fire. Timing was set up as follows:

Timing mark on crankshaft pulley dead in line with pointer on chain housing
( I have the flywheel locking tool but couldnt get it in)
No 1 cylinder cam lobes up and leaning in towards each other
Two dots on flats at rear of camshaft facing upwards and flats level
Arrows on camshaft sprockets point up

I am curious that this set up makes the 'pointer' behind the inlet sprocket face down but this appears to be correct per photos in Bentleys. Strange as the sensor for it is 90 degrees before that?

I can get a 25 thou feeler gauge between the bottom of the inlet cams and the followers but not on the exhaust. Is this normal? I'm thinking bent valves - but on all 6??

Advice appreciated. Especially the kind that says 'just turn this screw and all will be well'
