hi i have a 2007 vectra sri 1.8 and it has a rattle when starting from cold which goes away after a few seconds , i took the sump off to check for dirt inside and it was clean , oil pick up clean etc , the rattle isnt bad like worn bearings bad oil pressure etc but it sounds low enough , its only done 80000 km and its a nice quiet engine apart from starting from cold , also i noticed it has a very slight leak from behind the air con pump area , looks like a oil cooler/heat exchanger weeping...
