OK, i had the complete intake off again today, tripple checked all the vacuum hoses, bending twisting etc, no cracks or tears, they are either new or very good, so id say its not a vacuum leak, the rattle sounds like timing chain, or loud pinking, and SOMETIMES happens at cold start, although the engine does'nt stall when cold..... i can discount the chain i think, because at all other times the engine is smooth and silent..... so, im back to thinking its a pinking from too much advance on the ignition........ thats why i changed the knock sensors, jee, they were badly cracked and most of the insulation was missing.......also, whoever fitted them, did'nt use a torque wrench, id estimate they were at around 40-50 pounds instead of the 12 they should be; --- knuckle busting job too.as for flow meter, mine has the square topped meter as shown, part # 1   ive just swopped back to my original one, now conducting hot start tests with various time sitting for heat soak.this is the last issue with the car, ive changed the blower fan to get rid of an annoying random squeal, ive changed the wiper mechanisim so the wipers no longer hit the bonnet, and ive changed the cam position sensor which has (i think, fingers crossed) cured the random 'hic-up' when cruising........... <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /> just this hot start issue to cure now and i can put her back into daily 160 kilometer commute service.</blockquote>
