gti6 motor i had for my 205 was sitting for about 3 months before it went in and now its running. Ive done a timing belt on it also but the exhaust cam slipped my grasp and now im worried that ive bent a valve(s). very light tap, wouldnt be heard in the cabin i dont think, becomes louder at higher RPM. also worth noting that the oil is penrite 10w-50. cant drive it yet but only let it sit idling at most 5 minutes.
If its not a sticky lifter (which i hope should clear up if driven hot) and the oil isnt too thin for the motor (less than 100,000km i think about 70k), is it ok to leave it as it is? if its bent it would be only slightly bent from clashing with each other when i timed it up (got a solid lower pulley too). Im an apprentice and cant afford 16 valves & guides, cylinder head service and a head gasket at the moment, was hoping maybe leave it 6 months or so if im to pull it apart then to upgrade the motor..
