we have a 51 plate vauxhall comdo 1.7dti van which developed a strange noise from the cambelt area.....on inspection we found the nut that holds the oil pump drive pulley in place had worked loose....tightened it up and it came loose again 100 miles or so later....since then we have been tightening up everyday for the last week.
But now it wont fully tighten,hope its not stripped!!!! but have also noticed that the amount of visible thread has increased by about 2mm....we are a bit baffled so are hoping someone on here might know what the crack is

probably a stretch bolt of some sort. As said, get a new part on it asap

come across this a few times too
last time i changed the pulley and bolt as per usual , thread locked it in and it still came undone so i put a new pump in .
pulley was about Ł35 , bolt Ł5 , pump Ł90 ish

u have to replace the pump,pulley and nut and the cambelt i personally change the tensioner and roller as well its straight forward to do u have to use sealant as well as some gaskets when u use the sealant be careful not to cover up the small pressure releif hole in the pump otherwise it will piss out dont drop the sump no need no take out the 2 studs u will see when u do the job

Paul Hall
